MEMORANDUM OPINION
WILLIAM D. QUARLES, JR., District Judge.Melvin F. Sherin,1 individually and as personal representative of the Estate of Roberta L. Sherin, sued Union Carbide Corporation (“Union Carbide”)2 in an asbestos-related product liability action. Pending are Union Carbide’s motion in limine, ECF No. 179, motion for summary judgment, ECF No. 178, and motion for partial summary judgment, ECF No. 181. For the following reasons, the motions will be granted in part and denied in part.
I. Background3
A. Facts
1. Exposure to Asbestos Dust
This case arises from Mrs. Sherin’s fatal mesothelioma, allegedly caused by asbestos fibers she inhaled during the construction of her home and while washing the clothing Mr. Sherin wore while visiting construction sites as a carpet salesman. See ECF Nos. 2,183 at 1.4
*283In 1968, Mr. and Mrs. Sherin bought an undeveloped lot at 8528 Brattle Road, Pikesville, Maryland. ECF No. 183 at 4. In the spring of 1969, construction of their new home (“Brattle Road”) began; it was completed in early 1970. Id. Mr. and Mrs. Sherin visited the Brattle Road construction site every day for almost one year. ECF Nos. 182 at 3, 183-2 at 22. Each visit lasted between 20 and 90 minutes. ECF No. 183-2 at 23.
While at the site, Mr. Sherin saw buckets of “Georgia-Pacific” and “Gold-Bond”5 joint compound. ECF Nos. 183 at 4, 183-2 at 26-28. Mr. Sherin described the buckets as “black,” “bluish-white,” and “white” plastic and metal. ECF No. 183-2 at 26-28. Contractors used the joint compound to tape the seams of the drywall sheets and then sanded • the joint compound. Id. at 25.6 Mr. Sherin saw “tremendous” clouds of dust generated by this work. ECF Nos. 183 at 4, 183-2 at 25-26. Mrs. Sherin would sweep the dust off the floor so that their children could sit and play. ECF No. 183-2 at 15, 25-26.
From 1968 to 1976, Mr. Sherin was a sales representative for Crown Products, a carpet manufacturer, covering Maryland, Northern Virginia, and the District of Columbia. Id. at 10-12.7 Mr. Sherin visited eight to ten construction sites each month; he ultimately visited “hundreds” of sites. Id. at 42, 49, 53. While at the sites, Mr. Sherin saw buckets of “Georgia-Pacific” and “Gold Bond” joint compound being used “[m]any times.” Id. at 54, 57. Dust from the construction sites adhered to his outer clothing, some of which was washed by Mrs. Sherin. Id. at 48, 52, 55.
Doctors Abraham and Kipen testified about Mrs. Sherin’s mesothelioma. See ECF Nos. 183-19; 183-20. Dr. Abraham testified that “[i]f laundering [Mr. Sherin’s] clothes created aerosolized asbestos fibers that she inhaled, that would be part of her cumulative exposures and part of the causation of her mesothelioma.” ECF No. 183-19 at 14. Dr. Abraham also testified that every exposure would be a contributing cause, and that each exposure increases the risk of mesothelioma because “there is a dose-response relationship.” Id. At 11-12. Dr. Kipen characterized Mrs. Sherin’s exposure as “substantial domestic exposure” as a result of her laundering of Mr. Sherin’s clothes for many years. ECF No. 183-20 at 7.8 He opined that Mrs. Sherin’s mesothelioma resulted from her “cumulative exposure to asbestos dust.” Id. at 5-6.
2. Union Carbide’s Sales
Between 1963 and 1985 Union Carbide sold raw chrysotile asbestos fiber referred to as “SG-210” or “Calidria” to third-party manufacturers — including Geopgia-Pacific and National Gypsum — who incorporated it into their products. Id. at 2.
Sales to Georgia-Pacific began in the late 1960s9 or early 1970s. See ECF No. *284188-6 at 119-122. Until 1978, Georgia-Pacific manufactured “Ready Mix” joint compound and supplied the Baltimore area from its Akron, New York plant. ECF No. 188-10 at 7-8. Thereafter, manufacturing for the Baltimore area shifted to Georgia-Pacific’s Milford, Virginia plant. Id. Until 1970, the various Ready Mix formulas contained asbestos supplied by Phillip Carey. ECF No. 183-8 at 10. After September 1970, all Ready Mix formulas used Calidria supplied by Union Carbide. Id.10
There is conflicting evidence about when National Gypsum, the manufacturer of “Gold Bond” joint compound, began using Calidria. Responses to interrogatories in a prior case stated that — “around 1967”— National Gypsum began using Calidria. ECF No. 183-11 at 9. Interoffice correspondence from National Gypsum’s Long Beach, California, plant states that — in 1968 — National Gypsum began testing Calidria as a replacement asbestos fiber. ECF No. 186-16 at 2.11 Donald Doty, a former National Gypsum employee, testified that — as of early 1969 — National Gypsum used SG-210 exclusively in its joint compound formula. ECF No. 183-13 at 15. However, Doty’s testimony consisted of him reading from a Regional Plant Manager’s Meeting Report about National Gypsum’s West Coast operations. ECF Nos. 186-1 at 2-3,183-14 at 5-6. National Gypsum supplied the Baltimore area from its Baltimore plant. ECF Nos. 186 at 4 n. 6,186-1 at 6.
National Gypsum business records show substantial sales of Calidria from Union Carbide to National Gypsum’s Baltimore plant. ECF No. 183-18. The earliest recorded sale was in April 1969. Id. at 23, 42. Almost all the invoices, however, are dated 1971 to 1975. See generally id.
3. Union Carbide’s Awareness of the Dangers of Asbestos Exposure and its Warnings to Customers
Controversy about the safety of asbestos dates from the 1940s. See ECF No. 183-24 at 6.12 A 1947 Report of Preliminary Dust Investigation (“Dust Investigation Report”) prepared by the Industrial Hygiene Foundation of America, Inc. (“IHF”), of which Union Carbide is allegedly a founding member, stated that information available at that time “[did] not permit complete assurance that five million [particles per cubic foot]13 is thoroughly safe nor has information been developed permitting a better estimate of safe dustiness.” ECF No. 183-25 at 4, 23. The Dust Investigation Report urged further *285study to measure “any remaining hazard in the dust zone below five million for the elimination of future asbestosis depends upon the degree of control effected now.” Id.
In 1956, Henry Field Smith, Jr., Ph.D., authored a journal article for Union Carbide and the Mellon Institute, in which he stated that threshold limits and maximum allowance concentrations were misleading. See ECF no. 183-29 at 3. According to Dr. Smith, the use of such terms suggested that “human response” to exposures less than those amounts would be “negligible,” when “no such description can truthfully attach! ] to most of them.” Id.
In 1965, Union Carbide prepared an internal memorandum in response to news reports concerning the possible carcinogenic properties of asbestos. See ECF No. 183-32. The memorandum recommended that personnel responding to customer inquiries after the news reports refer to an Asbestos Toxicology Report (“Toxicology Report”) prepared by Union Carbide’s Director of Toxicology, Dr. C.U. Dernehl. See id. at 1. The Toxicology Report states that although “[i]t has been known for many years that some persons working in asbestos production were prone to develop a disabling lung disease,” “a man can work a 40-hour week for a lifetime without developing asbestosis” if exposures were kept below five million particles per cubic foot. See id. at 3.14
In 1967, I.C. Sayers prepared a report for Union Carbide in the United Kingdom, titled “Asbestos as a Health Hazard in the United Kingdom” (“Sayers Report”). See ECF No. 183-36. The Sayers Report states that mesothelioma is associated with inhaling asbestos; that “[mjesothelioma is the most disturbing” of diseases attributable to asbestos; and that it can occur after “brief exposure,” possibly as low as “three months,” or, according to “[sjome authorities!,] ... a single brief exposure might be sufficient.” Id. at 11. The Sayers Report also mentions an article published on October 31, 1965, by the Sunday Times, describing a dock worker’s wife who died of mesothelioma; her only exposure to asbestos was from washing her husband’s work clothes. See id.' at 4.
In June 1967, Dr. Dernehl reviewed the Sayers Report, finding it “reasonably accurate.” ECF No. 183-38 at 1. Dr. Dernehl stated that “[i]t is probable that the 5 million particles per cubic foot will not be acceptable for the prevention of mesothelioma.” Id. at 2.
In May-June 1972, the Occupational Safety and Health Administration (“OSHA”) published “Asbestos: Airborne Danger” (“Asbestos Article”). See ECF No. 183-55. The Asbestos Article states that incidences of mesothelioma are “now appearing at an unprecedented' rate,” and “[r]esearehers are linking it to asbestos exposure, however slight.” Id. at 6. The Asbestos Article further states that “[a]sbestos contamination holds an increasing threat to the general public.” Id. at 8. “Unsuspecting passers-by in the vicinity of construction sites or families of workers who return home with dusty clothing are among those exposed to this hazard.” Id.
In May 1973, Union Carbide’s Medical Department sent a letter to its Law Department citing the Medical Department’s *286disagreements with various conclusions drawn by the Mining and Metals Division following its Calidria Asbestos study. See ECF No. 183-59. The Medical Department compared the Mining and Metals Division’s conclusions with criteria for asbestos exposure set by the National Institute of Occupational Safety and Health (“NIOSH”). See id. at 1. The Medical Department stated:
— In response to the conclusion by Mining and Metals Division that asbestosis and lung cancer occurred only in workers with long-term exposure to large amounts of dust, NIOSH had reported positive x-ray findings of asbestos exposure in individuals known to be exposed for just one day and had referenced “earlier data of family cases with reasonably short and/or low levels of exposure”; and
— In response to the conclusion that “there is no evidence that the general public is in any danger from the amount of asbestos fiber in the community air,” NIOSH had previously stated that “some question may be raised of a possible neighborhood exposure.”
See id. at 1-2, 4-5. The Medical Department also noted that various slides produced by the Mining and Metals Division were “misleading” or contained “half-truths.” Id. at 6-7.
Beginning in 1968, Union Carbide included warnings on its bags of Calidria asbestos15 and — in 1972 — it modified the warning to comply with newly-enacted OSHA regulations. See ECF No. 178-1 at 18. Georgia-Pacific employees who handled bags of Calidria asbestos testified that they did not recall seeing any warnings printed on the bags or receiving information from Union Carbide about the health hazards of asbestos. See ECF Nos. 183-73 at 3; 183-74 at 2. Union Carbide no longer has any of the bags that were used during the time it sold Calidria through 1985. See ECF No. 183 at 29.
Beginning in 1964, Union Carbide provided its Asbestos Toxicology Report to all customers. See ECF No. 178-4 at 5, 9. Union Carbide also provided its customers with various regulations, reports, and literature on the topic of health risks associated with asbestos. See id. The 1967 Sayers Report, however, was not distributed to customers. See ECF No. 183-39 at 18.
In 1972, Union Carbide began providing customers with its Material Safety Data Sheet about Calidria asbestos (“Calidria Data Sheet”). Id. The Calidria Data Sheet stated that Calidria contained no hazardous ingredients, although it provided guidance on airborne exposure to asbestos and noted that “[pjrolonged overexposure may result in lung damage.” ECF No. 183-56.
Also in 1972, Union Carbide’s Mining and Metals Division recommended responding to customer concerns about asbestos by stating that “[ajsbestos is proven harmful only when TLV’s are exceeded for 10-30 years” and that “[i]t is not a proven fact that asbestos dust causes cancer when regulations are observed.” ECF No. 183-50 at 1.
In 1973, Union Carbide internal correspondence directed personnel to inform customers that “asbestos is not a carcinogen” under OSHA regulations, and stated that “[a]s you know, the answer to the same question in the broad sense is not as clear-cut,” and medical opinion varies from “[ajsbestos is a very dangerous carcinogen” to “[ujnder certain exposure condi*287tions certain types of asbestos may be carcinogenic.” ECF No. 183-60 at 1.
In the early 1970s, Union Carbide employees who visited customers completed a “Report of Call.” See ECF Nos. 45-49. Two Reports' of Call suggest that Union Carbide customers were dissatisfied with the asbestos-related information they had received. See ECF Nos. 183-45, 183-19. One Report of Call states that a customer complained that “the only information that Carbide has furnished him with regard to this subject in print is our Asbestos Toxicology report and some information concerning methods and equipment for determining dust levels.” ECF No. 183-49 at 1. The customer described the Asbestos Toxicology Report as “atrocious,” said that it posed more questions than it answered, and requested more specific recommendations for safe use of Calidria. Id.
B. Procedural History
On December 21, 2011, Mr. Sherin sued Union Carbide, and others,16 under various theories of recovery.17 ECF No. 2. On September 30, 2013, Union Carbide moved in limine to exclude hearsay and speculative product identification testimony. ECF No. 179. Also on September 30, 2013, Union Carbide moved for summary judgment on all claims, based on lack of evidence of causation or duty, ECF No. 178, and moved for partial summary judgment on the issues of breach of warranty, fraud, conspiracy, aiding and abetting, and punitive damages, ECF No. 181. On October 18, 2013, Mr. Sherin opposed the motion in limine, ECF No. 182, and the motion for summary judgment, ECF No. 183.18 On November 4, 2013, Union Carbide replied. ECF Nos. 185,186.
II. Analysis
A. Union Carbide’s Motion in Limine
Union Carbide asserts that Mr. Sherin’s testimony should be excluded because it is speculative and inadmissible hearsay. See ECF 179-1.
1. Personal Knowledge
Union Carbide asserts that Mr. Sherin’s testimony is “unfounded” and “speculative” because he did not purchase or use the buckets, and that he is “simply guessing about what was in them and who made them.” ECF Nos. 179-1 at 2, 4, 185 at 3. Mr. Sherin asserts that his eye-witness product identification testimony meets the foundational requirements of Federal Rule of Evidence 602. See ECF No. 182 at 3-4.
Under Rule 602, a witness may not testify about matters outside his personal knowledge. Testimony should be excluded for lack of personal knowledge only when “in the proper exercise of the trial court’s discretion it finds that the witness could not have actually perceived or observed *288that which he testifies to.” MBAFB Fed. Credit Union v. Cumis Ins. Soc’y, Inc., 681 F.2d 930, 932 (4th Cir.1982); see also United States v. Martin, 29 Fed.Appx. 178 (4th Cir.2002) (unpublished) (affirming admissibility of lay testimony identifying controlled substances with which the defendants were charged).
Here, Mr. Sherin testified that he and Mrs. Sherin visited the construction site of their new home each day for nearly one year. ECF No. 182 at 3. During that time, he frequently saw “clouds of visible dust” generated by the sanding of joint compound contained in buckets labeled “Georgia-Pacific” and “Gold Bond.” Id. Mr. Sherin also testified that he observed those same buckets at “ ‘hundreds’ of construction sites in Maryland, Virginia, and Washington D.C.” while working as a sales representative for Crown Products. Id.
There has been no showing that it was “nearly impossible” for Mr. Sherin to “actually perceive[ ] or observe[ ]” the buckets labeled “Georgia-Pacific” and “Gold Bond.” See MBAFB Fed. Credit Union, 681 F.2d at 932. “The quality of a witness’s observations is not an issue for foundations; it is a matter for impeachment.” Adkins v. Dirickson, 523 F.Supp. 1281, 1284-85 (E.D.Pa.1981). Mr. Sherin’s testimony meets the requirements of Rule 602. Accordingly, the Court will deny Union Carbide’s motion in limine to exclude Mr. Sherin’s testimony as speculative.
2. Hearsay
Union Carbide argues that Mr. Sherin’s product identification testimony asserts that “the buckets contained joint compounds made by Georgia-Pacific, National Gypsum, and U.S. Gypsum,” and, thus, is barred by the rule against hearsay. ECF No. 179-1 at 4. Mr. Sherin argues that his testimony is not hearsay because it is not offered “to prove the contents (the actual ingredients) of the materials contained in the buckets,” but is “circumstantial evidence of the joint compounds’ manufacturers.” ECF No. 182 at 7.
Hearsay is an out-of-court statement offered in court to prove the truth of the matter asserted in the statement. Fed. R.Evid. 801(c)(1)." A statement is an oral or written assertion or nonverbal conduct “if the person [making the statement] intended it as an assertion.” Fed.R.Evid. 801(a). Hearsay is generally inadmissible unless an exception applies. Fed.R.Evid. 802. Whether product identification testimony is hearsay depends on the purpose for which the evidence is offered, see Commonwealth v. Harvey, 446 Pa.Super. 395, 666 A.2d 1108, 1111 (1995), and is of first impression in this circuit.19
One line of cases holds that product labels represent out-of-court statements subject to the hearsay rules when offered to prove the contents of the package. See Sternhagen v. Dow Co., 108 F.Supp.2d 1113, 1116 (D.Mont.1999) (testimony that plaintiff saw “defendants’ labels on barrels of 2, 4-D” was hearsay); see also DiCola v. White Bros. Performance Products, Inc., 158 Cal.App.4th 666, 69 Cal.Rptr.3d 888, 900 (2008)20 (testimony that package label read “Burly Brands” inadmissible *289hearsay to prove that the package contained a “Burly Brands” model product).21
Another line of cases holds that testimony about a product’s manufacturer by reference to its label is not a statement subject to the hearsay rules, but is circumstantial evidence of the manufacturer.22 See Bolton v. Air & Liquid Sys. Corp., No. 2:12-60128-ER, 2013 WL 2477169, at *1 n. 1 (E.D.Pa. Apr. 30, 2013)23 (hearsay objection to plaintiffs testimony that packaging was labeled “Buffalo” was “without merit”); see also Los Angeles News Serv. v. CBS Broadcasting, Inc., 305 F.3d 924 (9th Cir.2002), amended, 313 F.3d 1093 (9th Cir.2002) (“CBS” logo appearing in the opening frames of a videotape was circumstantial evidence of the videotape’s origin); Harvey, 666 A.2d at 1111-12. Harvey involved the sale of liquor to minors; at trial, the Commonwealth asked the minors to identify the brand of beer they consumed. Id. The Court held that because the testimony sought to establish the beer’s manufacturer, and not its alcohol content, the “label was not an assertion subject to the hearsay rule.” Id. at 1112.
Cases addressing inscriptions about the place of manufacture are in accord with this view. See United States v. Scott, No. 2:13CR164, 2014 WL 2808802, at *4 (E.D.Va. June 20, 2014) (holding that “Made in China” inscription was circumstantial evidence that product was made in China and not a statement by the manufacturer); United States v. Koch, 625 F.3d 470, 480 (8th Cir.2010) (“China” inscription on computer and flash drive labels not inadmissible hearsay).24
Harvey is instructive because the Court had to determine whether the testimony identified the product’s manufacturer or its content. See id. at 1111 (stating that “[h]ad the Commonwealth relied upon the Busch label to establish the alcohol content of the beverage, such testimony would have fallen squarely within the dictates of’ cases applying the rule against hearsay). Other courts adhering to this view have generally not had to make that distinction. *290See United States v. Buchanan, 604 F.3d 517, 522 (8th Cir.2010) (matching inscriptions on a key and a safe not hearsay).25 But see Hill v. Joseph T. Ryerson & Son, Inc., 165 W.Va. 22, 268 S.E.2d 296, 309-10 (1980) (testimony describing pipe bearing label “RT 1419” hearsay as it “strongly implicate[d]” the identity of the manufacturer; admitted under the business records exception to the rule against hearsay).
As Mr. Sherin did not testify about the contents of or ingredients in the buckets, this case differs from those finding that testimony about a label was hearsay when offered to prove a container’s contents. See Sternhagen, 108 F.Supp.2d at 1116 (testimony hearsay because offered to prove that barrels contained Defendants’ 2, 4-D product, and, thus, that plaintiff was exposed to 2, 4-D). For the same reason, this case also differs from those finding that testimony about ingredients on a label was hearsay. See, e.g., Reemer v. State, 835 N.E.2d 1005, 1007-09 (Ind.2005).
Here, Mr. Sherin has testified that he saw contractors using joint compound in buckets labeled “Georgia-Pacific” and “Gold Bond,” and that he saw those buckets while visiting construction sites as part of his job. ECF No. 182 at 3. The bucket labels imply, but do not assert, that the joint compounds in the buckets were manufactured by Georgia-Pacific and National Gypsum. See Binder & Kaye, The Hearsay Handbook, Part 1, § 2:4 (4th Ed.) (West 2011). The labels are not assertions subject to the hearsay rules but are circumstantial evidence of the manufacturer identities. See Harvey, 666 A.2d at 1112. As with any circumstantial evidence, “[t]he party seeking to avoid the inference for which the evidence is offered must attempt the explanation and it is for the fact finder to determine whether he succeeds.” United States v. Snow, 517 F.2d 441, 444 (9th Cir.1975).
Even assuming that Mr. Sherin’s testimony about the bucket labels was hearsay, it would be admissible under the residual exception to the rule against hearsay.26
Under Federal Rule of Evidence 807(a), hearsay that is not covered by a specific hearsay exception may be admissible if:
(1) the statement has equivalent circumstantial guarantees of trustworthiness [as the exceptions contained in Rules 803 and 804];
(2) it is offered as evidence of a material fact;
(3) it is more probative on the point for which it is offered than any other evidence that the proponent can obtain through reasonable efforts; and
(4) admitting it will best serve the purposes of these rules and the interests of justice.
Although Rule 807 is narrowly construed, see United States v. Dunford, 148 F.3d 385, 394 (4th Cir.1998), “[w]hen the choice is between evidence which is less than best and no evidence at all, only clear folly would dictate an across-the-board policy of doing without.” Morgan v. Foretich, 846 F.2d 941, 943 (4th Cir.1988) (quoting Fed. R.Evid. art. VIII advisory committee’s note). Here, all four requirements are met.
*291First, Mr. Sherin’s testimony has circumstantial guarantees of trustworthiness. He saw the buckets many times over an eight-year period during the construction of Brattle Road and while visiting construction sites as part of his job, and he described their color and shape. See ECF No. 182 at 1, 3, 12.27 Second, Mr. Sherin’s testimony is offered as evidence of a material fact: that Mrs. Sherin was exposed to asbestos-containing joint compound manufactured by Georgia-Pacific and National Gypsum. See id. at 12. Third, Mr. Sherin’s testimony is more probative than any other evidence that Mr. Sherin can readily obtain. Because 30 years have passed since Mrs. Sherin’s exposure, Mr. Sherin has had great difficulty locating physical evidence, records, or other witness testimony. See id. at 12-13. Finally, admission of Mr. Sherin’s testimony will serve the interests of justice. Direct evidence of exposure to asbestos is often scarce, see id. at 13; excluding Mr. Sherin’s testimony may result in “no evidence at all,” see Morgan, 846 F.2d at 943.
Accordingly, even if the bucket labels were construed as assertions subject to the hearsay rules, Mr. Sherin’s testimony would be admissible under the residual exception. See Scott, 2014 WL 2808802, at *4.28 Therefore, this Court will deny Union Carbide’s motion in limine to exclude Mr. Sherin’s testimony as hearsay.
B. Union Carbide’s Motion for Summary Judgment
1. Legal Standard for Summary Judgment
The Court “shall grant summary judgment if the movant shows that there is no genuine dispute as to any material fact and the movant is entitled to judgment as a matter of law.” Fed.R.Civ.P. 56(a);29 Celotex Corp. v. Catrett, 477 U.S. 317, 322, 106 S.Ct. 2548, 91 L.Ed.2d 265 (1986). In considering the motion, the judge’s function is “not ... to weigh the evidence and determine the truth of the matter but to determine whether there is a genuine issue for trial.” Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 249, 106 S.Ct. 2505, 91 L.Ed.2d 202 (1986). A dispute about a material fact is genuine “if the evidence is such that a reasonable jury could return a verdict for the nonmoving party.” Id. at 248, 106 S.Ct. 2505.
The Court must “view the evidence in the light most favorable to ... the nonmovant and draw all reasonable inferences in [its] favor,” Dennis v. Columbia Colleton Med. Ctr., Inc., 290 F.3d 639, 645 (4th Cir.2002), but the Court must abide by the “affirmative obligation of the trial judge to *292prevent factually unsupported claims and defenses from proceeding to trial,” Bouchat v. Balt Ravens Football Club, Inc., 846 F.3d 514, 526 (4th Cir.2003) (citation and internal quotation marks omitted). The opposing party must produce evidence upon which a reasonable fact finder could rely. Celotex Corp., 477 U.S. at 322-23, 106 S.Ct. 2548. The mere existence of a “scintilla” of evidence is insufficient to preclude summary judgment. Anderson, 477 U.S. at 252, 106 S.Ct. 2505.
2. Union Carbide’s Motion
Union Carbide has raised four grounds in its motion for summary judgment. See ECF No. 178-1 at 2-3.30 In reviewing this motion the Court will apply Maryland substantive law. See Erie Railroad v. Tompkins, 304 U.S. 64, 58 S.Ct. 817, 82 L.Ed. 1188 (1938).31
i. Admissibility of Mr. Sherin’s testimony
Union Carbide asserts that it is entitled to summary judgment because Mr. Sherin’s testimony is speculative and inadmissible hearsay and, thus, there is no admissible evidence establishing that the joint compounds he saw were manufactured by Georgia-Pacific or National Gypsum. See ECF No. 178-1 at 6-7. As this Court has 'determined that Mr. Sherin’s testimony met the personal knowledge requirement of Federal Rule of Evidence 602, and was not inadmissible hearsay, see infra II.A.2, Union Carbide’s motion for summary judgment on this basis will be denied.
ii. Evidence of Exposure
Union Carbide asserts that it is entitled to summary judgment because, even if Mr. Sherin saw workers using Georgia-Pacific or National Gypsum joint compound, “there is no evidence that any particular joint compound, to which Mrs. Sherin was actually exposed, in fact contained Calidria as an ingredient.” ECF No. 178-1 at 8. Mr. Sherin contends that his testimony establishes that — -from 1969 to 1970 — Mrs. Sherin inhaled asbestos-containing dust at their Brattle Road home construction site and — from 1968 to 1976 — on the clothes worn by Mr. Sherin,32 and that the asbestos was “mined, marketed, and supplied” by Union Carbide. ECF No. 183 at 4-6.
In an asbestos products liability action, the plaintiff must present evidence of exposure to the defendant’s asbestos. See Reiter v. Pneumo Abex, LLC, 417 Md. 57, 8 A.3d 725, 729 (2010); Owens-Illinois, Inc. v. Zenobia, 325 Md. 665, 602 A.2d 1182, 1184 (1992).33 This evidence may be circumstantial. Eagle-Picher Indus., Inc. v. Balbos, 326 Md. 179, 604 A.2d 445, 460 (1992) (citing Roehling v. National Gyp*293sum Co. Gold Bond Bldg. Products, 786 F.2d 1225, 1228 (4th Cir.1986) (“The evidence, circumstantial as it may be, need only establish that [plaintiff] was in the same vicinity as witnesses who can identify the products causing the asbestos dust that all people in that area, not just the product handlers, inhaled.”)).
Mr. Sherin’s testimony is circumstantial evidence of Mrs. Sherin’s exposure at the Brattle Road construction site where he recalled seeing “Georgia-Pacific” and “Gold Bond” joint compound in use. ECF No. 183-2 at 21-23, 26-28. Mrs. Sherin was exposed to asbestos dust when she swept the dust.off the floor so that their children could sit and play. Id. at 15, 25-26.
Mr. Sherin also testified that — from 1968 until 1976 — he visited “hundreds” of construction sites where Georgia-Pacific and Gold Bond joint compound was used. Id. at 42, 49, 53-54.34 When Mr. Sherin returned home, his dusty work clothes were washed by Mrs. Sherin. Id. at 48, 52, 55.
In addition to evidence of exposure, Mr. Sherin must also show that the Georgia-Pacific and National Gypsum asbestos dust contained Calidria asbestos fibers.
a. Georgia-Pacific
Mr. Sherin supports his assertion that the Georgia-Pacific joint compound contained Calidria with deposition testimony by John L. Myers, a former employee of Union Carbide. See ECF No. 183-6. Myers testified that sales to “that sector of the market” including Georgia-Pacific began in the early 1970s and possibly was as early as the late 1960s based on a Calidria brochure dated October 1968. See id. at 119,122.
Mr. Sherin also relies on the deposition testimony of former Georgia-Pacific employees C. William Lehnert, see ECF No. 183-8, and Howard A. Schutte, see ECF No. 183-10. According to Schutte, until 1973, Georgia-Pacific manufactured Ready Mix supplied to the Baltimore area at its Akron, New York plant. See id. at 7-8. Thereafter, it was manufactured by Georgia-Pacific’s Milford, Virginia plant. Id. Lehnert testified, however, that until September 1970, virtually all the formulas used to manufacture Ready Mix at the Akron plant used asbestos produced by Phillip Carey, and that after September, 1970, all available formulas used SG-210. ECF No. 183-8 at 10. Lehnert’s handwritten notes indicate that the Milford plant used SG-210 in its Ready Mix joint compound from June 1973 at least until January 1975. See ECF No. 183-9.
b. National Gypsum
Mr. Sherin relies in part on National Gypsum’s responses to interrogatories in an earlier asbestos case. See ECF No. 183-11. The responses generally state that National Gypsum began using SG-210 asbestos fiber in its products, including Gold Bond, “[a]round 1967.” Id. at 9.
Mr. Sherin also relies on deposition testimony of Donald Doty, a former market service manager for National Gypsum, to establish that — as of early 1969 — National Gypsum began using SG-210 exclusively in its joint compound formula. See ECF No. 183 at 11. However, in the deposition testimony to which Mr. Sherin refers, Doty is reading from a Regional Plant Manager’s Meeting Report about National Gypsum’s West Coast operations. See ECF Nos. 186-1 at 2-3, 183-14 at 5-6. National Gypsum supplies to the Baltimore area would not have shipped from its West Coast operations, but from its Baltimore *294plant. See ECF Nos. 186 at 4 n. 6, 186-1 at 6.
Mr. Sherin has produced business records showing Union Carbide’s sales of SG-210 to National Gypsum’s Baltimore plant from 1969 until 1976. See ECF No. 183— 18.35 The earliest recorded shipment occurred in April 1969, see id. at 23, around the time construction began on the Brattle Road home, see ECF No. 183-2.36 Although Mr. Sherin has not produced evidence that Calidria shipped in April 1969 was mixed into the joint compound formula used at the Brattle Road home in 1969,37 he has raised a genuine dispute of material fact over whether it was.
Based on the foregoing evidence, though a jury could not reasonably infer that Mrs. Sherin inhaled Calidria asbestos dust from Georgia-Pacific joint compound at the Brattle Road worksite or from washing Mr. Sherin’s work clothes prior to September 1970, a jury could find that Mrs. Sherin sustained take-home exposure after September 1970. Furthermore, a jury could find that Mrs. Sherin inhaled Calidria asbestos dust from National Gypsum joint compound at the Brattle Road work-site and — from 1969 to 1976 — from washing Mr. Sherin’s work clothes.
iii. Substantial Factor Causation
Union Carbide asserts that it is entitled to summary judgment because Mr. Sherin cannot show that Mrs. Sherin’s exposure to Calidria, if any, was a substantial factor in causing Mrs. Sherin’s mesothelioma. See ECF No. -178-1 at 10-11. At best, Union Carbide asserts, Mr. Sherin has merely shown that Calidria “was incorporated in certain formulas, of certain manufacturers, at certain times.” Id. at 11. Mr. Sherin asserts that expert medical testimony establishes that Mrs. Sherin was exposed to Union Carbide’s asbestos “in' quantities sufficient to have caused her malignant mesothelioma.” ECF No. 183 at 12-13.38
Under Maryland law, the plaintiff must show that the defendant’s asbestos was a substantial factor in causing her harm. See Shetterly v. Raymark Indus., Inc., 117 F.3d 776, 780 (4th Cir.1997); Lohrmann v. Pittsburgh Corning Corp., 782 F.2d 1156, 1162 (4th Cir.1986). In this case, because Mrs. Sherin did not work directly with asbestos products, she is considered a “bystander.” See Balbos, 604 A.2d at 460.
Whether a bystander’s exposure to asbestos products is legally sufficient to find substantial-factor causation is fact *295specific. See id. Factors to consider include the frequency of the asbestos product’s use, the regularity of a plaintiffs exposure, and the time and distance proximity of a plaintiff to the product’s use. See id.; Reiter v. AC and S, Inc., 179 Md.App. 645, 947 A.2d 570, 572 (2008), aff'd sub nom. Reiter v. Pneumo Abex, LLC, 417 Md. 57, 8 A.3d 725 (Md.2010) (evidence that plaintiffs worked in “same massive facility” as cranes allegedly releasing asbestos fibers insufficient to find substantial factor causation).39 Evidence concerning medical causation must also be considered. See Georgia-Pac. Corp. v. Pransky, 369 Md. 360, 800 A.2d 722, 725 (2002) (citing Lockwood v. AC & S, Inc., 109 Wash.2d 235, 744 P.2d 605, 613 (1987)).
Mr. Sherin has provided sufficient evidence for a jury to reasonably infer that the Balbos “regular, frequent, and proximate exposure” test is met. See Balbos, 604 A.2d at 460.
Here, Mr. Sherin testified that — between 1968 and 1976 — he visited construction sites eight to ten times each month. ECF No. 183-2 at 53. Defining the relevant time period as 1969 to 1976,40 and performing basic math, Mr. Sherin visited between 672 and 840 construction sites during that time. Mr. Sherin testified that he saw buckets of Georgia-Pacific and Gold Bond joint compound being used “[mjany times” during those visits. Id. at 57.41 Dust from the joint compound adhered to his socks, shoes, pants, and jacket that were washed by Mrs. Sherin. Id. at 55, 52.
Mr. Sherin also offers medical testimony by Drs. Abraham and Kipen. See ECF Nos. 183-19, 183-20. Dr. Abraham testified that each exposure to asbestos fibers while washing Mr. Sherin’s clothes would be a contributing cause of Mrs. Sherin’s mesothelioma and that each exposure increases the risk of mesothelioma. ECF No. 183-19 at 11-12, 14. Dr. Kipen testified that, in his opinion, Mrs. Sherin’s mesothelioma resulted from her “cumulative exposure to asbestos dust” over many years of washing Mr. Sherin’s clothes. Id. at 5-7 (describing Mrs. Sherin’s exposure as “substantial domestic exposure”).
From Mrs. Sherin’s laundry exposure and the medical testimony, a jury could reasonably infer that Union Carbide’s asbestos fiber was a substantial factor in causing Mrs. Sherin’s mesothelioma,
iv. Tort Duty to Warn
Union Carbide asserts that it is entitled to summary judgment as it did not owe Mrs. Sherin a duty to warn her about the dangers of asbestos because-her exposure to asbestos — and her development of mesothelioma — was not foreseeable. See ECF No. 178-1 at 12-13. Union Carbide also asserts that there was no feasible way *296for it to have warned Mrs. Sherin and that it discharged its duty, if any, by reasonably relying on warnings it provided to its customers. See id. at 15-18.42
a. Existence of the Duty
Union Carbide asserts that — before 1972 — it did not owe Mrs. Sherin a duty because the “generally available scientific information had not yet clearly suggested that ‘take-home’ exposures to asbestos were a potential health hazard.” ECF No. 178-1 at 12.43 Union' Carbide further asserts that — post-1972—Mr. ' Sherin’s presence on worksites, giving rise to the take-home exposure, was not foreseeable. Id. at 13. Mr. Sherin contends that Union Carbide was aware of the dangers of take-home exposure to asbestos in 1967, and, thus, that Mrs. Sherin’s exposure was foreseeable. See ECF No. 183 at 44.44
“The existence of a legal duty is a question of law, to be decided by the court.” Gourdine v. Crews, 405 Md. 722, 955 A.2d 769, 775 (2008) (citing Doe v. Pharmacia & Upjohn Co., Inc., 388 Md. 407, 879 A.2d 1088, 1092 (2005)).45 Under Maryland law, foreseeability of harm is a crucial — though not sole — factor in deter*297mining whether a defendant had a duty to warn those who might suffer harm from the defendant’s conduct. See Georgia Pac., LLC v. Farrar, 432 Md. 523, 69 A.3d 1028, 1033 (2013).46 Foreseeability of harm turns (1) on what “the supplier knew or had ‘reason to know ” about the dangers of asbestos when the warning should have been given,47 and (2) whether “the defendant should have recognized” that the plaintiff was “in a significant zone of danger.”48 Farrar, 69 A.3d at 1034; Balbos, 604 A.2d at 454.
There is no duty to warn, however, if the warning cannot feasibly be implemented or have practical effect. Farrar, 69 A.3d at 1039 (trial court erred in finding a duty to warn in 1968-69 because “there was no practical way that any warning given by [the defendant] to any of the suggested intermediaries would or could have avoided that danger”).
Here, Mr. Sherin has presented sufficient evidence from which a jury could reasonably infer that Union Carbide knew or had reason to know of the dangers of household exposure to asbestos before 1972.
The 1947 Dust Investigation Report prepared by IHF stated that information available then “[did] not permit complete assurance that five million [particles per cubic foot]49 is thoroughly safe nor has information been developed permitting a better estimate of safe dustiness.” ECF No. 183-25 at 4, 23. Similarly, in 1956, Henry Field Smith, Jr., Ph.D.’s journal article for Union Carbide and the Mellon Institute stated that threshold limits and maximum allowance concentrations were misleading. See ECF no. 183-29 at 3.
On the issue of take-home exposure, Mr. Sherin presented the 1967 Sayers Report, which states that mesothelioma is associated with inhaling asbestos; that “[m]esothelioma is the most disturbing” of diseases attributable to asbestos; and that it can occur after “brief exposure,” possibly as low as “three months,” or, according to “[s]ome authorities!,] ... a single brief exposure' might be sufficient.” ECF No. 183-36 at 11. The Sayers Report mentions an October 31, 1965 Sunday Times *298article describing a case of a dock worker’s wife who died of mesothelioma after asbestos exposure from washing her husband’s work clothes. See id. at 4. In June 1967, Dr. Dernehl found the Sayers Report “reasonably accurate.” ECF No. 183-38 at 1. Dr. Dernehl stated “[i]t is probable that the 5 million particles per cubic foot will not be acceptable for the prevention of mesothelioma.” Id. at 2.
Based on the foregoing, the Court finds that a jury could reasonably infer that Union Carbide had, as Mr. Sherin asserts, “clear notice of the dangers of ‘take-home’ exposures” before 1972.
Mr. Sherin presented additional evidence to support his assertion that Union Carbide’s awareness of the dangers of exposure to asbestos dust increased throughout the 1970s. For example, Mr. Sherin presented the 1972 “Asbestos Article” warning about the danger from slight exposure to asbestos, including take-home exposure. See ECF No. 183-55. Mr. Sherin also relies on the May 1973 letter prepared by Union Carbide’s Medical Department disagreeing with the Mining and Metals Division’s conclusions resulting from its Calidria Asbestos study. See ECF No. 183-59. The Medical Department compared the Mining and Metals Division’s conclusions with criteria for asbestos set forth by NIOSH and found that its conclusions minimized the health hazards associated with asbestos exposure. See id. at 1-2, 4-5.
The Court is not persuaded by Union Carbide’s assertion that Mr. Sherin’s presence oh worksites was not foreseeable. ECF No. 178-1 at 13. Mr. Sherin visited worksites to convince builders to install his products at the builders’ next construction locations. See ECF No. 183-2 at 36. These visits were not uncommon; they occurred eight to ten times per month. See id. at 53. Thus, from the evidence of awareness of take-home exposure and Mr. Sherin’s job, a jury could reasonably find that Union Carbide knew or should have known of the dangers of take-home asbestos exposure after 1972.
Before imposing a duty to warn, however, the Court must satisfy itself that Union Carbide could have feasibly and effectively implemented that duty. See Farrar, 69 A.3d at 1039. Union Carbide asserts that Mr. Sherin has provided no evidence of a “feasible way for Union Carbide to have warn[ed] Mrs. Sherin.” ECF No. 186 at 10. Farrar, however, does not require Union Carbide to have reached Mrs. Sherin directly. The Farrar Court stated that “there was no practical way that any warning given by [Georgia-Pacific] to any of the suggested intermediaries would or could have avoided that danger.” Farrar, 69 A.3d at 1039 (emphasis added). Farrar, thus, leaves open the possibility that the feasibility of the warning may be determined by assessing whether the defendant could feasibly have better warned its intermediaries.
Mr. Sherin does not directly address Farrar s holding about feasibility of warnings.50 Mr. Sherin asserts, however, that Union Carbide “affirmatively deceived its customers about the hazards of Calidria Asbestos” and “had ample opportunity and ability to provide warnings about the hazards of asbestos and the potential harm to users.” ECF No. 183 at 32, 35. Drawing all reasonable inferences in Mr. Sherin’s favor, see Dennis, 290 F.3d at 645, Mr. Sherin’s assertions could be construed as an argument that Union Carbide could *299feasibly have issued better warnings to its customers.
Union Carbide asserts that it warned its customers of the dangers of asbestos and provided safe-handling instructions. See ECF No. 178-1 at 16. Beginning in 1968, Union Carbide included warnings on its bags of Calidria asbestos and — in 1972 — it modified the warning to comply with newly-enacted OSHA regulations. See ECF No. 178-1 at 18. Union Carbide internal correspondence states, however, that the 1968 labeling used on its asbestos packaging was “weak.” See ECF No. 183-79 at 31.51
As further support of the adequacy of its warnings, Union Carbide presented an affidavit by John L. Myers, a former Union Carbide employee. See ECF No. 178-4. Myers states that Union Carbide provided its customers with various regulations, reports, and literature about health risks associated with asbestos. See id. at 6. Beginning in 1964, Union Carbide provided its Asbestos Toxicology Report to all customers. Id. at 5. In 1972, Union Carbide began providing customers with its Calidria Data Sheet. Id. at 6.
Mr. Sherin disputes the adequacy of Union Carbide’s warnings, asserting that Union Carbide deliberately misled its customers on the dangers of asbestos and “providefd] the least amount of information possible.” See ECF No. 183 at 27, 36. In support, Mr. Sherin points to internal Union Carbide documents. In 1972, Union Carbide’s Mining and Metals Division recommended responding to a customer’s concerns by stating that “fa]sbestos is proven harmful only when TLV’s are exceeded for 10-30 years” and that “fi]t is not a proven fact that asbestos dust causes cancer when regulations are observed.” ECF No. 183-50 at 1. In 1973, Union Carbide directed personnel to inform customers that “asbestos is not a carcinogen” under OSHA regulations, while acknowledging “fa]s you know, the answer to the same question in the broad sense is not as clear-cut,” and medical opinion varies from “fa]sbestos is a very dangerous carcinogen” to “fujnder certain exposure conditions certain types of asbestos may be carcinogenic.” ECF No. 183-60 at 1.
Mr. Sherin also presents Union Carbide “Reports of Call” suggesting Union Carbide customer dissatisfaction with the information they had received. See ECF Nos. 183-45, 183-49. In one Report of Call, the customer apparently stated that “the only information that Carbide has furnished him with regard to this subject in print is our Asbestos Toxicology report and some information concerning methods and equipment for determining dust levels.” ECF No. 183-49 at 1. The customer described the Asbestos Toxicology Report as “atrocious,” said that that it posed more questions than it answered, and requested more specific recommendations for safe use of Calidria. Id.
Mr. Sherin asserts that the Calidria Data Sheet stated that Calidria contained no hazardous ingredients, see ECF Nos. 183 at 25, 183-56, although it provided guidance on airborne exposure to asbestos and noted that “[prolonged overexposure may result in lung damage.” ECF No. 183-56. Mr. Sherin asserts that the list of documents provided to Union Carbide customers was inadequate to fully inform them of the dangers of asbestos. See ECF No 27. For example, the 1967 Say*300ers Report was not distributed to customers. See ECF No. 183 at 19, 183-39 at 18.
Based on the foregoing, a jury could reasonably infer that it was feasible for Union Carbide to more fully inform its customers about the health hazards associated with asbestos dust. Under Farrar, however, Mr. Sherin must also provide evidence that improved warnings would have effectively prevented Mrs. Sherin’s take-home exposure to asbestos dust.52 Mr. Sherin has not provided any evidence that better warnings by Union Carbide would have altered Mrs. Sherin’s take-home exposure.53 Thus, this Court will grant Union Carbide’s motion for summary judgment on the issue of its duty to warn Mrs. Sherin.54
C. Union carbide’s Motion for Partial Summary Judgment
Union Carbide seeks partial summary judgment on claims involving breach of warranty, fraud, conspiracy, aiding and abetting, and punitive damages. See ECF No. 181. That motion is unopposed, and there is no evidence in the record supporting those claims. Accordingly, Union Carbide’s motion for partial summary judgment will be granted.
III. Conclusion
For the reasons stated above, the motion in limine will be denied, the motion for summary judgment will be granted in part and denied in part, and the motion for partial summary judgment will be granted.

Burdulis, 753 F.3d 255, 262-64 (1st Cir.2014); In re T.D., 71 Ill.Dec. 20, 450 N.E.2d at 458 (glue label "sufficiently trustworthy to be an exception” to the hearsay rule; Moore v.

DiCola v. White Bros. Performance Products, Inc., 158 Cal.App.4th 666, 69 Cal.Rptr.3d 888, 900 (2008), did not address whether the "Burly Brands” label fell within a recognized hearsay exception as the Plaintiffs did not present such an argument.
.Federal Rule of Civil Procedure 56(a), which "carries forward the summary-judgment standard expressed in former subdivision (c),” changed "genuine 'issue' [to] genuine 'dispute,' ” and restored the word " 'shall' ... to express the direction to grant summary judgment.” Fed.R.Civ.P. 56 advisory committee's note.
.Union Carbide also asserts, without citing-any authority, that it is entitled to summary judgment because Mr. Sherin "never identified U.S. Gypsum as an alleged source of Mrs. Sherin’s Calidria exposure,” ECF No. 178-1 at 2 n. 4, and apparently was raising the market share theory of liability. Although Count Six of the Complaint alleges market share liability, see ECF No. 2, Mr: Sherin contends that his "claims are not based on the theory of market share liability,” but rather "traditional theories of negligence,” ECF No 183 at 45. Maryland does not recognize market share liability. See Reiter v. AC and S, Inc., 179 Md.App. 645, 947 A.2d 570, 573 (2008) aff'd sub now. Reiter v. Pneumo Abex, LLC, 417 Md. 57, 8 A.3d 725 (2010); see also Lee v. Baxter Health Care Corp., 898 F.2d 146 (4th Cir.1990) (applying Maryland law).

. Referred to as "take-home” exposure.
. See also Georgia-Pacific Corp. v. Pransky, 369 Md. 360, 800 A.2d 722, 724-25 (2002) (“[Tjhe plaintiff must have been in or very near the presence of the asbestos-containing product and able to inhale fibers.”).
. Mr. Sherin could not recall specific dates on which he observed the joint compound, but stated that he saw it "many” times. ECF No. 183-2 at 57.
. The business records primarily contain invoices dated 1971 to 1975. See ECF No. 183— 18. Union Carbide’s sales ledger, however, reflects shipment of Calidria to National Gypsum's Baltimore plant in April, 1969. See id. at 23, 42.
. Mr. Sherin testified that construction began "maybe in the spring, spring of 1969," though he could not precisely recall. ECF No. 183-2 at 21.
. Mr. Sherin testified that the family moved in to the Brattle Road home "before 1970 ... [o]r right at the beginning of 1970.” ECF No. 183-2 at 29. It is reasonable to infer, then, that the application of joint compound during diywall installation occurred sometime in 1969.
.Mr. Sherin contends that surviving a motion for summary judgment merely requires that it produce “some evidence” of exposure, and that the substantial factor determination is for the jury to decide. See ECF No. 183 at 4. Substantial factor causation may appropriately be determined — depending on the evidence or lack thereof — at the summary judgment stage. See AC and S, Inc., 947 A.2d at 572 (2008) (resolving substantial factor causation in favor of defendant on motion for summary judgment); see also Harper v. Anchor Packing Co., No. GLR-12-460, 2014 WL 3828387 (D.Md. Aug. 1, 2014) (same).
.See also Pransky, 800 A.2d at 724. In Pransky, the daughter of a heating and air conditioning contractor argued that her mesothelioma was caused by exposure to asbestos-containing dust generated by her father’s several-month long conversion of their basement to a recreation room, and for the next ten years by dust emanating from the compound used on the ceiling. Id. at 723-24. The Pransky court found there was sufficient evidence to affirm the jury's finding that Ms. Pransky's exposure to the defendant’s asbestos was a substantial factor in causing her mesothelioma. Id. at 723-26.
. Because the Court has determined that Mr. Sherin’s evidence is sufficient to find that Mrs. Sherin inhaled Calidria-containing asbestos dust from 1969 to 1976, this section will not consider her alleged exposure prior to 1969 for the purpose of determining whether there is sufficient evidence of substantial factor causation.
. Mr. Sherin further stated that “[o]n every job site, every house, [buckets of Georgia-Pacific and Gold Bond joint compound] were being used. Now, not every house had it, obviously. But it was so common, it's all , over the place.” ECF No. 183-2 at 54.
. Union Carbide further asserts that, even if it unreasonably relied on its customers to provide warnings about the danger of asbestos, Mr. Sherin must show "that the inadequate warning caused the injury.” ECF No. 178-1 at 19. As authority, Union Carbide cites to Ames v. Apothecon, Inc., 431 F.Supp.2d 566, 573 (D.Md.2006), a case involving a manufacturer’s printed warnings on a prescription drug label. That case' is inapposite here. Ames interpreted the "learned intermediary” doctrine applicable in the context of doctor-patient relationships. See id. ("[A] product defect claim based on insufficient warnings cannot survive summary judgment if stronger warnings would not have altered the conduct of the prescribing physician.”) (alteration in original) (quoting Motus v. Pfizer Inc., 358 F.3d 659, 661 (9th Cir.2004) ("Because the doctor testified that he did not read the warning label ... before prescribing the drug to Dr. Motus, the adequacy of Pfizer’s warnings is irrelevant to the disposition of this case.”)). Here, it is enough that Mr. Sherin shows (1) that Union Carbide owed a duty to warn, and (2) that Union Carbide failed to properly discharge its duty by unreasonably relying on its customers to provide the warning.
. Union Carbide relies on Georgia Pac., LLC v. Farrar, 432 Md. 523, 69 A.3d 1028, 1037-38 (2013), for the proposition that, before 1972, it did not owe Mrs. Sherin a duty. In Farrar, although the Court discussed the state of scientific knowledge before the 1972 regulations issued by the Occupational Safety and Health Administration (“OSHA”), it resolved the issue on the grounds of impracticability of issuing a warning. See id. at 1039 (”[E]ven if Georgia Pacific should have foreseen back in 1968-69 that individuals such as Ms. Farrar were in a zone of danger, there was no practical way that any warning given by it to any of the suggested intermediaries would or could have avoided that danger.").
. Mr. Sherin also relies on Farrar, wherein the Court observed that liability arising from pre-1972 exposures was less likely to attach "at least in the absence of evidence that the defendant was aware, or should have been aware, of the danger to household members at the time.” Farrar, 69 A.3d at 1038. Because, Mr. Sherin argues, Union Carbide was aware of the danger to household members, Farrar's focus on the 1972 OSHA regulations is not dispositive here. See ECF No. 183 at 43-45.
. The standard to be applied in failure to warn cases sounding in strict liability and negligence is the same. See Kennedy v. Mobay Corp., 84 Md.App. 397, 579 A.2d 1191, 1198 (1990) (“Maryland has long recognized a duty on the part of sellers to warn of latent dangers attendant upon a proper use of the products they sell, where injury is foreseeable. The standard applied in that regard, under all three theories of negligence, breach of implied warranty, and strict liability, has been that stated in Restatement (Second) of Torts § 388.”) (quoting Dechello v. Johnson Enterprises, 74 Md.App. 228, 536 A.2d 1203 (1988)). Under either theory, the key inquiry is, "Was the warning adequate?” Id. (quoting Werner v. Upjohn Co., Inc., 628 F.2d 848, 858 (4th Cir.1980)).
. See also Henley v. Prince George's Cnty., 305 Md. 320, 503 A.2d 1333, 1340-41 (1986) ("[T]he question of foreseeable identification of a plaintiff” is particularly "relevant to the determination of the existence of a duty to warn.”).
. A supplier has "reason to know” when "it has information from which a person of reasonable intelligence or of the superior intelligence of the actor would infer that the fact in question exists, or that such person would govern his conduct upon the assumption that such fact exists.” Eagle-Picher Indus., Inc. v. Balbos, 326 Md. 179, 604 A.2d 445, 454 (1992) (quoting Restatement (Second) of Torts: Reason to Know; Should Know § 12 (1965)).
. In Farrar, the Court adopted the Restatement view on foreseeability:
The general standard ..., clearly applicable to product liability cases and, in particular, to exposure to asbestos, is stated in § 388 of the Restatement (Second) of Torts — that the duty extends "to those whom the supplier should expect to use the chattel” with the consent of the person to whom it is supplied "or to be endangered by its probable use.” Comment d. to § 388 emphasizes that the supplier is subject to liability "not only to those for whose use the chattel is supplied but also to third persons whom the supplier should expect to be endangered by its use.”
Id. at 1033-34 (footnote omitted) (quoting Restatement (Second) of Torts: Chattel Known to be Dangerous for Intended Use § 388 (1965)).
.The maximum allowable concentration standard for asbestos dust recommended at the time by the American Conference of Governmental and Industrial Hygiene. See ECF Nos. 183-25 at 22, 183 at 15.
. Mr. Sherin’s discussion of Farrar is limited to the Court's discussion of pre-1972 liability. See ECF No. 183 at 43-45.
. Mr. Sherin has presented deposition testimony by Georgia-Pacific employees who handled bags of Calidria asbestos and who stated that they did not recall seeing any warnings printed on the bags or receiving information from Union Carbide about the health hazards of asbestos. See ECF Nos. 183-73 at 3, 183— 74 at 2.
.In Farrar the Court granted summary judgment for the defendant when
The best that the plaintiff offers in her brief was for Georgia Pacific to have "spread the word” to distributors of the product, the owners of land on which the product was used, contractors who supervised the workers, and union officials, and rely on them to inform everyone working in the vicinity of asbestos. Presumably, the word to be spread was that asbestos dust collected on work clothes could be dangerous if brought into the home.
Farrar, 69 A.3d at 1039.
. Union Carbide sold asbestos to product manufacturers, which sold finished products to suppliers; the suppliers sold the products to contractors; these contractors used the products that exposed Mrs. Sherin to asbestos at the new home and on Mr. Sherin’s clothing. See ECF No. 178-1 at 16.
. Because this Court finds that Union Carbide did not owe Mrs. Sherin a duty to warn, it will not consider Union Carbide's alternative reliance on the sophisticated user defense.
