The fire upon and explosion of the S.S. Grandcamp at Texas City, Texas, while she was loading a cargo of Fertilizer Grade Ammonium Nitrate (FGAN) on April 16, 1947, resulted in more than 500 deaths, more than 3000 personal injuries, and tremendous destruction of and damage to property. It has become known as the Texas City Disaster. On May 5, 1947, two weeks after the disaster, the Republic of France, as owner, and Com-pagnie Generate Transatlantique (hereinafter referred to as the “French Line”), as agent of the owner or charterer of the vessel, filed a petition in the District Court for the Southern District of New York (Admiralty No. 149-248), pursuant to the Limitation of Liability Act, 46 U.S.C.A. §§ 182-189, praying for exoneration from or limitation of liability for damages resulting from the explosion. That New York limitation proceeding is still pending without trial or other disposition.
On October 17, 1947, within the six-month period prescribed by 46 U.S.C.A. § 185, the Republic of France and the French Line filed the present like petition for exoneration or limitation of liability in the District Court for the Southern District of Texas. A long delay in bringing the latter petition to trial has been occasioned by giving precedence to the suits under the Federal Tort Claims Act, 28 U.S.C. §§ 1346 and 2674, against the United States, the manufacturer of the FGAN. Eventually, this Court held that the United States was not liable, and its decision was affirmed by the Supreme Court. In re Texas City Disaster Litigation, 5 Cir., 1952, 197 F.2d 771, affirmed sub nom. Dalehite v. United States, 1953, 346 U.S. 15, 73 S.Ct. 956, 97 L.Ed. 1427.
Thereafter, in 1955 Congress enacted the Texas City Relief Act, 69 Stat. 707-709. That Act left insurance underwriters to bear their own losses, but provided for payment of uninsured claims in an amount not exceeding $25,000.00 for any one claim. Pursuant to the provisions of that statute, the United States paid approximately $16,000,000.00 to victims of the disaster and obtained from the recipients assignments of their claims for death, personal injuries and property damages which totalled approximately $70,000,000.00. Thereafter, in May 1957, the United States filed in this proceeding an amended claim based upon these assignments, not for the $16,000,000.00 paid but for approximately $70,000,000.-00, the amount originally asserted by these claimants.
The claims of all persons who made assignments to the United States were dismissed on January 27, 1958. Many persons who had not made assignments to the United States thereafter voluntarily withdrew their claims. The only remaining claimant, other than the United States, is the Texas City Railway Terminal Co. That Company did not file under the Texas City Relief Act because it was not willing to assign an uninsured loss of nearly five million dollars for the $25,-000.00 maximum allowed under the Relief Act. In addition to its assigned claims, the United States filed a claim in the amount of $350,000, as successor to the Reconstruction Finance Corporation, for the loss of goods in a warehouse awaiting loading on another vessel.
Neither of petitioners here was a party to the Dalehite case. The cases are alike to the extent that each arises out of the Texas City Disaster. Sensibly, the trial of the present case was shortened by the introduction by agreement of the testimony in Dalehite of 86 of the total of 133 witnesses in that case. Four of the witnesses in Dalehite again testified in this case, and an additional 25 witnesses testified in open court during thirteen days of trial. So that the findings and decision of the district court in this ease were based not only on a large part of the evidence taken in Dalehite, but also on a voluminous record now comprising some 2400 pages of additional testimony. The issues in the two cases, particularly at the *397present stage of this limitation proceeding, are not identical.
The findings of fact and conclusions of law of the district court in this case comprise some 43 pages of the printed record, and have been published at 171 F.Supp. 497, 511 and at 1959 A.M.C. 547. Based upon such findings and conclusions, the district court entered an interlocutory decree granting the motion of the petitioners for leave to implead the United States,1 and denying the petitions for exoneration or limitation.2 This appeal is from that decree.
The only ultimate issue so far determined by the district court is that the petitioners are not entitled to exoneration from or limitation of liability. The merits of the claims or of the impleading petition have not yet been determined. The decree was captioned by the district court as an “Interlocutory Decree,” and for purposes of appellate jurisdiction we think that it must be so considered. See La Bourgogne, 1907, 210 U.S. 95, 112, 113, 28 S.Ct. 664, 52 L.Ed. 973. The jurisdiction of this Court of Appeals is that granted by 28 U.S.C. § 1292(a) (3):
“(a) The courts of appeals shall have jurisdiction of appeals from: * * * -x- * *
“(3) Interlocutory decrees of such district courts or the judges thereof determining the rights and liabilities of the parties to admiralty cases in which appeals from final decrees are allowed.”
While interlocutory for purposes of appellate jurisdiction, this decree finally determined the rights and liabilities of the parties by denying the petition for exoneration from or limitation of liability. To that extent, the decree is not subject to the rule usually applicable to interlocutory decrees; 3 viz.: that in reaching its final decree the court may exercise its discretion to re-examine any or all of its findings which form the basis of the interlocutory decree. Instead, except as to the issues which were reserved to be determined on the impleader of the United States (see footnote 1, supra), the present decree is res judicata on the issue of liability for the damages caused by the explosion.4
*398The district court found that the Grandcamp was unseaworthy in that she was improperly manned and improperly stowed, and that the Grandcamp’s unseaworthiness was within the privity and knowledge of the petitioners.5 The district court found also that the master and the petitioners were guilty of fault and negligence both in the origin of the fire 6 and in the failure to extinguish it in its incipient stage.7* The court concluded:
“From the foregoing, it follows that by reason of the fault and negligence of the petitioners, and the unseaworthiness of the vessel, all of which was within the privity and knowledge of petitioners, neither is entitled to exoneration from or limitation of liability under § 183, Title 46 U.S.C.A.” 8
All of the claims having been filed, and there being no claims for loss of or damage to cargo, it is apparent that the fire statute, 46 U.S.C.A. § 182, is not applicable, and that consideration can be restricted to limitation of liability, 46 U.S.C.A. § 183. It is apparent also that there are no claims to which seaworthiness, not in itself amounting to negligence,9 can apply.
The findings of fault and negligence which appellants challenge on this appeal are those pertaining to the cause of the fire, and to the procedures that should have been used in attempting to extinguish the fire at its incipiency.10
We are relieved from entering into an exhaustive review of this voluminous record to reach a decision as to whether or not those findings of fact are clearly er*399roneous11 by the following considerations. All of the claims for personal injury, death, and property damage resulted not directly from fire but from explosion. The district court found no more than that the Master could have foreseen the possibility of explosion:
“The Master could and reasonably should have foreseen and anticipated the danger of a disastrous fire, with the possibility of explosion, in failing to prevent smoking in the presence or proximity of the FGAN. His negligence in this regard constituted a proximate cause of the fire, the resultant explosion, and the damages which ensued.8
“8 In connection with this finding as to ‘foreseeability’, it is undoubtedly true that the force and devastating effects of this explosion shocked and surprised the scientific field as well as the transportation industry. What was not generally recognized before Texas City was (a) that ammonium nitrate would cause a detonation of such magnitude in the absence of great confinement and pressure (as within a bomb), and (b), that fire and heat alone would cause such detonation, without an initial or booster detonation; or according to one theory, with such initial detonation resulting from an explosion of accumulated gases, which in turn come from the heated and decomposing ammonium nitrate.
“From the literature and information generally available, I do not believe, that, in the exercise of ordinary care, the Master could have foreseen the probability of an explosion of this sort, even in the presence of fire. This finding should be interpreted in this light, and is based on the premises that, as he could foresee danger from fire from his negligent conduct, the ‘foreseeability’ test is met, and it is not necessary that he be able to foresee the extent of the damage which may ensue.”12
In Texas, as elsewhere, not only proximate causal connection but also the very existence of a duty the breach of which will constitute actionable negligence depends upon reasonable foreseeability of consequences.13
The appellants urge as their “principal point” that, “even if unseaworthiness, fault and negligence be conceded, the district court, on the basis of its own findings, erred as a matter of law in holding that the claimed negligence which resulted in fire was the proximate cause of the injuries which resulted from the successive explosions, as its finding as to ‘foreseeability’ does not meet the standard of Texas law which was recognized by this Court in Texas-New Mexico Railway Company v. Bailey, 203 F.2d 647 (1953).” The appellants emphasize that the district court found that the master could reasonably have foreseen only the possibility of explosion, and could not have foreseen “the probability of an explosion of this sort,” and urge upon us our statement of the rule of liability in Texas, and the decisions upon which that statement is based:
“In Texas the test of whether a negligent act or omission is a proximate cause of an injury is whether ‘the wrong-doer might by the exercise of ordinary care have foreseen that some similar injury might result from the negligence.’ Atchison v. Texas & P. Ry. Co., 143 Tex. 466, 186 S.W.2d 228, 232; St. Louis B. & M. Ry. Co. v. Brack, Tex.Civ.App., 102 S.W.2d 261, 273.” (Emphasis supplied.) Texas-New Mexico Ry. Co. v. Bailey, 5 Cir., 1953, 203 F.2d 647, 649-650.
In their reply brief, the appellants concede that the case of Hopson v. *400Gulf Oil Corp., 1951,150 Tex. 1, 237 S.W. 2d 352, 356, quoted in Chicago, R. I. & P. R. Co. v. Goodson, 5 Cir., 1957, 242 F.2d 203, 207, correctly states the rule as follows:
“It is sufficient that the defendant would reasonably have anticipated consequences or an injury of the general nature of that which ensued.”
That rule is emphasized in the more recent opinion of Biggers v. Continental Bus System, 1957, 157 Tex. 351, 303 S.W. 2d 359, 364, 365, which disapproved a holding “that one’s negligence cannot be a proximate cause of an injury unless the precise manner or means of the injury resulting from the negligence can be foreseen” ; and, instead, held that:
“The true rule is correctly stated in Sullivan v. Flores where it is said that all that is necessary to establish that an actor’s negligent act is a proximate cause of an injury is proof that ‘As a person of ordinary intelligence and prudence, he should have anticipated the danger to others created by his negligent act, and the rule does not require that he anticipate just how injuries will grow out of that dangerous situation.’ [134 Tex. 55, 132 S.W.2d [110], 111.]”
The appellees argue with much force that the district court found that fault or negligence within the privity or knowledge of the owner or owners caused the fire and permitted it to increase in intensity, and that the fire caused the disastrous explosion. The appellees insist that that causal connection is sufficient within the holding of this Court in Chicago, R. I. & P. R. Co. v. Goodson, 5 Cir., 1957, 242 F.2d 203, 207:
“As to the element of foreseeableness which is stressed as being an important element of probable cause in Texas jurisprudence, we think it correct to say that whatever directly results by the operation of natural laws from the unlawful channelling of water onto another’s premises is a foreseeable event within the Texas rule.”
The fallacy in that chain of argument is that it is only the operation of natural forces theretofore recognized as normal which one is charged with foreseeing.
“Meaning of ‘normal.’ The actor as a reasonable man is required to anticipate and provide against the normal operation of natural forces. And here the word ‘normal’ is used to describe not only those forces which are constantly and habitually operating but also those forces which operate periodically or with a certain degree of frequency.”14
“Abnormal conditions of nature. The actor is not required to anticipate or provide against conditions of nature or the operation of natural forces which are of so unusual a character that the burden of providing for them would be out of all proportion to the chance of their existence or operation and the risk of harm to others involved in their possible existence or operation. It is therefore not necessary that a particular operation of the natural force be unprecedented; The likelihood of its recurrence may be so slight that in the aggregate the burden of constantly providing against it would be out of all proportion great as compared with the magnitude of the risk involved in the possibility of its recurrence.” 15
While in the present case there was some testimony in addition to the vast amount of evidence before the court in the Texas City Disaster Litigation, the district court still found it “undoubtedly true that the force and devastating effects of this explosion shocked and surprised the scientific field as well as the transportation industry.” The district court further found as to ammonium nitrate, which constituted approximately 95% of the FGAN, and which, with the *401benefit of hindsight, we now know to be the explosive part of the mixture:
“18. Despite its use as a principal ingredient of high explosives, at the time of the disaster ammonium nitrate was not, and is not now, classified as an ‘explosive’ for transportation purposes by the Interstate Commerce Commission or the Coast Guard. This is true because it was considered that to cause the detonation of ammonium nitrate, an initial shock or ‘booster’ of considerable magnitude was required. The chances of such an initial or booster detonation being encountered in normal conditions of transportation has always been considered so remote as to be negligible.” 16
Substantially all of the evidence is to the effect that the explosion as distinguished from the fire, could not reasonably have been foreseen. In the opinions of the four judges of our Court constituting the majority in the earlier ease, that was pretty clearly stated. Speaking for three of the judges, the writer had said:
“In this case, it can hardly be argued that the dangers of explosion from FGAN were so well known pri- or to the disaster that judgment or discretion were not called into exercise as to whether it should be manufactured at all and under what safeguards and warnings it should be distributed. Even if some danger were recognized, the necessity of providing means of existence to the devastated areas might have called for the exercise of discretion as to whether to take a ‘calculated risk’.” 17
Judge Strum expressed himself more positively :
“This explosion was wholly unprecedented. Prior to this disaster, there had been no known instances of explosions during land transit, while in stowage awaiting export, in the many shiploads previously shipped overseas, nor in this FGAN while part of it was stacked at the Texas City Terminal awaiting loading.” 18
When the case reached the Supreme Court, Mr. Justice Reed, speaking for the Court, said:
“ ‘There must be knowledge of a danger, not merely possible, but probable,’ MacPherson v. Buick Motor Co., 217 N.Y. 382, 389, 111 N.E. 1050, 1053, L.R.A.1916F, 696. Here, nothing so startling was adduced. The entirety of the evidence compels the view that FGAN was a material that former experience showed could be handled safely in the manner it was handled here.”19
We agree with the view so aptly expressed in the appellants’ brief:
“* * * It would be ironic indeed if the United States were permitted to impose liability for these claims on the Republic of France and the French Line in this litigation by claiming now that, unlike the officials and employees of the United States, the officials and employees of the French Government and the master of the Grandcamp should have known that FGAN was a dangerous explosive and that an explosion from fire should reasonably have been anticipated.”
It results that the judgment must be reversed and the cause remanded with directions to adjudge that the petitioners are not liable for any claim arising out of or consequent upon the explosion of the steamship Grandcamp.
Reversed and remanded with directions.
. In this connection, the district court’s findings were made “without determining whether the United States may have been at fault in any particular in connection with the manufacture or shipping of the EGAN, or, if so, the effect thereof as to the various types of claims which the United States asserts, if there be such negligence it was not the sole cause of the disaster (as petitioners contend).”
. The operative parts of the interlocutory decree read:
“Ordered, that the motion of petitioners for leave to implead the United States of America pursuant to the 56th Rule in Admiralty of the United States Supreme Court is hereby granted and allowed; and it is further
“Ordered, Adjudged and Decreed, that said petition of the Republic of France and the Oompagnie Generale Transat-lantique for exoneration from and/or limitation of liability should be and hereby is denied as to each of said petitioners.”

That was substantially the position taken by Government counsel upon oral argument:
“Judge Rives: Assuming that this interlocutory decree should be affirmed, where would you go from there? - What would the government have to prove before it got a final decree?
“Mr. Davis: Well, assuming that the interlocutory decree is confirmed, your Honor, it goes back to the District Court for further proceedings.
“Judge Rives: What issues remain open? That’s what I’m talking about.
“Mr. Davis: The questions of damages remain open, that is the principal one.
“Judge Rives: What issues as to liability remain open?
“Mr. Davis: What issues as to liability remain open? In respect of the peti*398tioners’ claim for exoneration and limitation of liability, that is the question that is up before this Court, and that question will be decided now.
“Judge Rives: What I am asking, before you get a judgment for your damages, have you still got to prove liability, and have they got to prove—
“Mr. Davis: Yes, I have to prove liability with respect to the various claims.
“Judge Rives: You have to prove your damages, of course?
“Mr. Davis: That is true, that is part of it.
“Judge Jones: When you go back, are you going to have the burden of showing that somebody on that morning threw a cigarette in the hold and that started the fire?
“Mr. Davis: No, sir, I will not have any such burden, your Honor.
“Judge Cameron: You take the position, or you think the Court findings have settled that finally?
“Mr. Davis: As to the cause of the fire, yes, sir, I think the Court findings have settled that. * * * * *
“Judge Cameron: You are taking the position that the question of negligence cannot be litigated again, that the Court has already found negligence on the part of this Petitioner, and that is the law of the case?
“Mr. Davis: The question of negligence, insofar as the petitioner is concerned, your Honor, cannot be litigated again. As respects the question of negligence as far as the United States is concerned, they can litigate that.
“Judge Rives: They can litigate that it was the United States’ fault and that they are in no position to recover; do you think that issue is still open?
“Mr. Davis: Certainly that issue is still open. In the final meeting of counsel before the Trial Judge we had no objection to his allowance of the in-pleading petition, we have no reserve about meeting that. We did not want to confuse things, and thought we should decide this question first and then we will decide that. Basically that goes to- the amount of damages.”
