Occupational Safety and Health Review Commission
________________________
(July 13, 2017)
Before TJOFLAT, WILLIAM PRYOR, and ROSENBAUM, Circuit Judges.
PER CURIAM:
The Secretary of Labor files this petition pursuant to 29 U.S.C. § 660(a) for
review of a final order of the Occupational Safety and Health Review Commission.
Case: 16-15792 Date Filed: 07/13/2017 Page: 2 of 24
The Commission adopted the decision of an administrative law judge (“ALJ”)
vacating the Secretary’s citation of Respondent Action Electric Company under 29
C.F.R. § 1910.147, which provides a standard for control of hazardous energy
during servicing and maintenance of machines and equipment. For the reasons set
forth below, we grant the Secretary’s petition for review, vacate the Commission’s
order, and remand with instructions to reinstate the Secretary’s citation.
I.
Action is a business located in Smyrna, Georgia, that provides electrical
services to other businesses. Since 2004, Action has performed repair work and
other services for the Gerdau Ameristeel US (“Gerdau”) steel mill in Cartersville,
Georgia. This case arose from the death of an Action apprentice onsite at Gerdau’s
mill during a visit on which he and an Action leadman had intended to replace
certain fans within the mill’s cooling bed. The apprentice, James Eddie Lanier, Jr.,
died after a counterweight within the cooling bed was de-energized and fell,
striking him.
Gerdau’s cooling bed is a collection of equipment that works together to
cool hot rolled steel so that later it may pass through a straightener. The heated
metal enters the cooling bed from a conveyor onto a set of rakes with grooves that
move the steel through the bed. While the steel moves along these rakes, 110 3-
foot-by-3-foot rotary fans blow air across the steel to cool it. The fans are bolted to
2
Case: 16-15792 Date Filed: 07/13/2017 Page: 3 of 24
a rail found just under the surface of the bed, approximately 8 feet above a
basement floor where technicians must walk to access the cooling bed’s
components. The basement contains a variety of equipment used to lift the cooling
bed and move the rakes: drive motors, rotating shafts, counterweights, chains,
drive pulleys, gear boxes, walking beams, and other equipment. Altogether, the
equipment occupies a space within the mill measuring roughly 325 feet long and
100 feet wide.
When the cooling bed is in operation, the only safe place for technicians in
the basement is a designated walkway marked by overhead lights, chain ropes, and
yellow floor paint. Sometimes, necessary maintenance requires technicians to
access other parts of the basement. To ensure the safety of technicians at those
times, Gerdau requires the entire cooling bed to be “locked out.” This process,
which takes the mill’s cooling-bed maintenance technician approximately 20
minutes to complete, involves de-energizing equipment within the cooling bed so
that it does not unexpectedly move and injure persons within the basement.
Gerdau employs safety protocols requiring a series of steps to be taken
before technicians can enter the cooling-bed basement to do maintenance.
Technicians entering the bed must complete a work authorization permit that is not
valid until lockout is complete, a successful lockout is verified, each technician
3
Case: 16-15792 Date Filed: 07/13/2017 Page: 4 of 24
entering the bed affixes a personal lock to a group lockout box, and the responsible
Gerdau technician signs the permit.
On the day of the accident, December 9, 2011, the two Action employees
prepared to replace three of the fans in the cooling bed, which required access to
the basement. Even though the Action leadman knew that the Gerdau technician
responsible for locking out the bed had not completed the lockout process, the
Action employees entered the basement and moved off the designated walkway.
They did so without affixing their personal locks to the group lockout box or
completing the work permit as required. Inside the basement, they began to
discuss the work to be completed and to observe the fans in need of replacement.
At that time, Gerdau’s technician, who could not see the Action employees from
where he was locking out the bed, began to de-energize the counterweights in the
bed as part of his lockout procedure. This caused one of the counterweights to fall
from an energized position and fatally strike Lanier.
II.
The Occupational Safety and Health Act of 1970 (the “Act”) “delegates
broad authority to the Secretary to promulgate different kinds of standards” for the
purpose of “ensuring safe and healthful working conditions for every working man
and woman in the Nation.” Indus. Union Dep’t, AFL-CIO v. Am. Petroleum Inst.,
448 U.S. 607, 611 (1980). The standard at issue in this case, the “lockout/tagout”
4
Case: 16-15792 Date Filed: 07/13/2017 Page: 5 of 24
(“LOTO”) standard, “covers the servicing and maintenance of machines and
equipment in which the unexpected energization or start up of the machines or
equipment, or release of stored energy could cause injury to employees.” 29
C.F.R. § 1910.147(a)(1)(i). Under the standard, employers must “establish a
program and utilize procedures for affixing appropriate lockout devices or tagout
devices to energy isolating devices, and to otherwise disable machines or
equipment to prevent” injuries caused by stored energy or unexpected energization.
Id. § 1910.147(a)(3)(i).
The Secretary is also responsible for enforcement of the LOTO standard and
other regulations. “If the Secretary (or the Secretary’s designate) determines upon
investigation that an employer is failing to comply with . . . a standard, the
Secretary is authorized to issue a citation and to assess the employer a monetary
penalty.” Martin v. Occupational Safety & Health Review Comm’n, 499 U.S. 144,
147 (1991) (citing 29 U.S.C. §§ 658-659, 666). An employer wishing to contest a
citation must receive an evidentiary hearing, after which the Commission renders
an order—either by adopting the findings and conclusions of an ALJ or by
conducting its own discretionary review of the ALJ’s decision—that affirms,
modifies, or vacates the citation or proposed penalty. Id. at 147-48 (citing 29
U.S.C. § 659(c)).
5
Case: 16-15792 Date Filed: 07/13/2017 Page: 6 of 24
Exercising the Secretary’s enforcement authority, the Occupational Safety
and Health Administration (“OSHA”) investigated the fatality in this case and
issued Action a citation for a serious violation 1 of 29 C.F.R.
§ 1910.147(f)(3)(ii)(D), for its employees’ failure to “affix a personal lockout or
tagout device” to a mechanism controlling the counterweights’ energy before
entering Gerdau’s cooling-bed basement to observe the fans. Action contested the
citation but did not dispute that its employees failed to affix LOTO devices.
Instead, Action argued the LOTO standard was inapplicable to its employees’
actions because the equipment causing the fatality, the counterweights, was not the
same equipment being serviced by the employees, the fans. Action argued
additionally that its employees were not working on the fans but simply viewing
them, so the LOTO standard was inapplicable for that reason also. The Secretary
responded that the cooling bed constituted one discrete mechanical system for the
purposes of the LOTO standard. On this view, Action employees were required to
control the energy of the entire cooling bed before conducting any work on the bed
that would expose them to danger.
After a hearing, the ALJ issued a decision vacating the citation, based
largely on Action’s reasoning. See Decision & Order, Action Electric Co., 25
1
A violation is classified as “serious” if “an employer knew about and failed to prevent
‘a substantial probability that death or serious physical harm could result from a condition which
exists’ in the workplace.” Fluor Daniel v. Occupational Safety & Health Review Comm’n, 295
F.3d 1232, 1239 (11th Cir. 2002) (quoting 29 U.S.C. § 666(k)).
6
Case: 16-15792 Date Filed: 07/13/2017 Page: 7 of 24
BNA OSHC 2138 (No. 12-1496, 2013) (ALJ) (“ALJ Decision & Order”). The
ALJ agreed with Action that the fans and counterweights were separate machines,
meaning that the LOTO standard did not require control of the counterweights’
energy when work was on the fans only. Id. at 8-11. The ALJ also ruled that the
employees were not “servicing” the fans under the meaning of the regulation
because the employees were too far away from the fans to be exposed to the
unexpected energization of or release of hazardous energy from them. Id. at 11-12.
The Secretary then filed a petition for discretionary review, which the
Commission granted. But because the two-person Commission could not arrive at
a unanimous decision, the Commission vacated its own direction for review and
adopted the ALJ’s decision as its final order. See Action Elec. Co., 25 BNA
OSHC 2120 (No. 12-1496, 2016), 2016 WL 3747113, at *1 (“Commission
Decision”). The Secretary now petitions this Court for review of that final order,
and we grant the petition.
III.
We will overturn the legal determinations of the Commission “only if they
are ‘arbitrary, capricious, an abuse of discretion, or otherwise not in accordance
with [the] law.’” Fluor Daniel v. Occupational Safety & Health Review Comm’n,
295 F.3d 1232, 1236 (11th Cir. 2002) (quoting 5 U.S.C. § 706(2)(A)). The
standard for disturbing the Commission’s factual findings is exacting: “‘if [the
7
Case: 16-15792 Date Filed: 07/13/2017 Page: 8 of 24
findings are] supported by substantial evidence on the record considered as a
whole, [they] shall be conclusive.’” Id. (quoting 29 U.S.C. § 660(a)).
IV.
When a regulation is ambiguous, the agency’s interpretation of its own
regulation is entitled to deference. Christensen v. Harris Cty., 529 U.S. 576, 588
(2000) (citing Auer v. Robbins, 519 U.S. 452, 461 (1997)). Here, although our
review is of the Commission’s decision, our primary deference is not to the
Commission’s interpretation of the law. Rather, we must accept as controlling the
Secretary’s reasonable interpretations of OSHA regulations despite whether they
conflict with the Commission’s reading. Martin, 499 U.S. at 156, 158 (“Giving the
Commission the power to substitute its reasonable interpretations for the
Secretary’s . . . would . . . clearly frustrate Congress’ intent to make a single
administrative actor accountable for the overall implementation of the Act’s policy
objectives . . . .”) (internal quotation marks omitted).
A.
The first question we decide is whether the LOTO standard required Action
employees to control the stored energy in the counterweights before entering the
cooling-bed basement to work on the fans. As the ALJ explained, “There is no
dispute that servicing and maintenance work on the fans would require compliance
with LOTO. The issue is whether the LOTO requirements apply to the
8
Case: 16-15792 Date Filed: 07/13/2017 Page: 9 of 24
counterweights if the servicing and maintenance work is only on the fans.” ALJ
Decision & Order at 7.
To answer this question, we must determine whether the cooling bed is one
“machine” for the purposes of the LOTO standard. See 29 C.F.R.
§ 1910.147(a)(1)(i) (“This standard covers the servicing and maintenance of
machines and equipment in which the . . . release of stored energy could cause
injury to employees.”). If the components of the cooling bed are together
considered one “machine,” then failure to follow the standard with respect to one
component of the bed—the counterweights causing the death—is grounds for a
citation even though Action’s employees were servicing a different component of
the bed—the cooling fans. Because the Secretary’s regulations lack any definition
of “machine,” the primary text of 29 C.F.R. § 1910.147 is too ambiguous to
establish whether Gerdau’s cooling bed is altogether one “machine.” So we must
look to the Secretary’s interpretation of the word in the regulation to determine if it
is reasonable. See Martin, 499 U.S. at 156, 158.
The Secretary has promulgated no authority explicitly defining the word
“machine” but has issued guidance explaining that “the LOTO standard does not
apply to equipment or machinery that is not the subject of the servicing and
maintenance activity and that functions independently from, and is not a sub-
system of, the machine/equipment being serviced or maintained.” The Control of
9
Case: 16-15792 Date Filed: 07/13/2017 Page: 10 of 24
Hazardous Energy – Enforcement Policy and Inspection Procedures, CPL 02-00-
147, at 1-10 (Feb. 11, 2008) (the “LOTO Directive”). Under the Secretary’s
interpretation, then, two pieces of equipment are part of one “machine” if they do
not function independently of one another or if both are sub-systems of a larger
machine. We afford this informal guidance deference because we find it to be a
persuasive interpretation of the regulation. See Martin, 499 U.S. at 157 (citing
Skidmore v. Swift & Co., 323 U.S. 134, 140 (1944)).
Relying in part on the LOTO Directive, the ALJ offered several reasons to
support its conclusion that “[t]he cooling bed is not itself a machine or piece of
equipment” but rather “a process that contains separate and distinct machines and
equipment.” ALJ Decision & Order at 8; see id. at 10 (quoting the LOTO
Directive). First, “[t]he fans are not fixed nor permanently attached to the
counterweights and rakes.” Id. at 8. Second, “[t]he mill’s written cooling bed
lockout procedure shows that the various machines and equipment need to be
separately locked out. . . . The omission of the fans from the written lockout
procedures underscores the fact the fans operated independently of the cooling
bed.” Id. at 9. Third, “[t]he fans and counterweights serve different purposes and
function differently, although part of the cooling bed process.” Id. Finally,
“[t]here are no electrical connections between the fans and drive chains that tell[]
the fans to turn on when the chain drives are on.” Id.
10
Case: 16-15792 Date Filed: 07/13/2017 Page: 11 of 24
Assuming for a moment that the LOTO Directive offers the most detailed
available guidance from the Secretary on the LOTO standard, these observations
by the ALJ would appear to be “conclusive” of our review due to the great
deference we owe the Commission’s findings of fact. See Fluor Daniel, 295 F.3d
at 1236; LOTO Directive at 1-10 (framing the question as whether one of two
pieces of equipment “functions independently from, and is not a sub-system of” the
other).
But the Commission did not take into account an additional, more detailed,
and binding source of administrative guidance that precludes the ALJ’s conclusion
that the fans and counterweights operated “independently”: the Secretary’s
briefing before the ALJ and the Commission in this very case. When the Secretary
offers interpretations of the LOTO standard or other regulations during the
administrative adjudication process, those interpretations are more than just
arguments by a party to an adversarial proceeding. Even in this context, the
Secretary’s interpretations of its own regulations constitute “agency action” and
“an exercise of the agency’s delegated lawmaking powers” under the Act. Martin,
499 U.S. at 157. Indeed, “the Secretary’s litigating position before the
Commission is as much an exercise of delegated lawmaking powers as is the
Secretary’s promulgation of a workplace health and safety standard.” Id.; see also
S.G. Loewendick & Sons, Inc. v. Reich, 70 F.3d 1291, 1294 (D.C. Cir. 1995)
11
Case: 16-15792 Date Filed: 07/13/2017 Page: 12 of 24
(“[W]e defer even where the Secretary offers his interpretation in the context of
litigation before the Commission.”).
In his briefing before the ALJ, the Secretary interpreted the LOTO standard
as applicable to all pieces of equipment that “function together as one system”
when servicing or maintenance is performed on any part of that system. See
Complainant’s Post-Hr’g Br. at 22, Action Electric Co., 25 BNA OSHC 2138 (No.
12-1496, 2013) (ALJ) (“ALJ Br.”). The Secretary further elucidated his
interpretation by responding to Action’s arguments within his brief. Action had
argued that the cooling bed was a collection of independently functioning
equipment just like the machinery at issue in another Commission case, The
Timken Co., 20 BNA OSHC 1070 (No. 97-0970, 2003), 2003 WL 1889150, at *1
(“Timken”). We pause here to address Timken because, although Timken itself is in
no way binding on this Court’s decision,2 a review of the facts and Commission
2
In its final decision, the Commission refers to the “precedential value” of its own
decisions. See Commission Decision, 2016 WL 3747113, at *1. But “precedent” is somewhat
of a misnomer, at least with regard to governing interpretations of OSHA regulations. “[T]he
Commission is authorized to review the Secretary’s interpretations for only consistency with the
regulatory language and for reasonableness. In addition, of course, Congress expressly charged
the Commission with making authoritative findings of fact and with applying the Secretary’s
standards to those facts in making a decision.” Martin, 499 U.S. at 154-55. This delegation of
power is much more limited than that to an adjudicatory body in an agency with a unitary
structure, where “adjudication operates as an appropriate mechanism not only for factfinding, but
also for the exercise of delegated lawmaking powers, including lawmaking by interpretation.”
Id. at 154. So although this Court owes deference to an interpretation of the regulation that
borrows language from Timken, this is so only because the Secretary chose to incorporate the
language in his own guidance. See LOTO Directive at 1-10.
12
Case: 16-15792 Date Filed: 07/13/2017 Page: 13 of 24
decision in that case is helpful as background to the Secretary’s promulgation of
new guidance on the LOTO standard in its briefing before the agency.
In Timken, a steel-mill employee was injured while servicing a teeming car,
which is a vessel that transports steel molds around a mill on top of a motorized
unit called a traverser. The employee suffered her injury because her feet were too
close to the traverser, which had not been locked out or tagged out prior to her
work on the inactivated teeming car. Timken, 2003 WL 1889150, at *1. In
reviewing the Secretary’s citation for a violation of the LOTO standard, the
Commissioners in Timken agreed that the LOTO standard did not apply to the
failure to lock out the traverser while the employee was servicing the teeming car.
One Commissioner wrote that the teeming car and traverser “functioned
independently” and that the Secretary failed to show they were “permanently
interconnected in a single, integrated system”; the other adopted this analysis and
noted additionally that mill operations continued normally on the day of the
accident, including “the movement of the other teeming cars onto the traverser.”
Id. at *4, *9.
By distinguishing the facts of Timken in his brief before the ALJ, the
Secretary clarified his interpretation of the LOTO standard. In this case, “the
various parts of the cooling bed . . . function together to perform th[e] process of
cooling the steel.” ALJ Br. at 25. Although it could be said that the traverser and
13
Case: 16-15792 Date Filed: 07/13/2017 Page: 14 of 24
teeming car in Timken also “function together to perform [a] process,” the
Secretary then made one additional, crucial distinction: in Timken, “the traverser
had other functions,” whereas here, the various components of the cooling bed
served no other purpose. Id. at 26. Incidentally, this distinction echoes the
conclusion of one of the Timken Commissioners that it was not sensible to apply
the LOTO standard in that case because the traverser was able to serve other
purposes while the teeming car being serviced was inactive. See Timken, 2003 WL
1889150, at *9.
After the ALJ ruled against the Secretary, the Secretary reiterated this
exclusive-function analysis before the Commission. 3 Framing the operative
question as whether “separate machine components function together as a single
integrated system,” the Secretary again noted that “the counterweights, fans and
other cooling bed sub-systems all operated simultaneously to execute the cooling
process,” unlike the traverser in Timken, which “moved on to another assignment”
once it completed its work with any one teeming car. Acting Sec’y of Labor’s Pet.
for Discretionary Review at 7, 10, Action Electric Co., 25 BNA OSHC 2120 (No.
3
The Secretary also argued before the Commission that “assessing whether the cooling
bed is a single integrated system for LOTO purposes requires evaluating the cooling bed’s
configuration . . . , and whether servicing the cooling fans exposed workers to the unexpected
energization of, or release of hazardous energy from, other parts of the cooling bed.” Opening
Br. for the Sec’y of Labor at 10, Action Electric Co., 25 BNA OSHC 2120 (No. 12-1496, 2016).
In essence, the Secretary’s position was that the danger posed by one piece of equipment due to
its proximity to another piece of equipment being serviced is relevant to the determination
whether the two pieces of equipment constitute a “machine.”
14
Case: 16-15792 Date Filed: 07/13/2017 Page: 15 of 24
12-1496, 2016) (emphasis added) (internal quotation marks omitted); see also
Opening Br. for the Sec’y of Labor at 13, Action Electric Co., 25 BNA OSHC
2120 (No. 12-1496, 2016) (“[U]nlike the traverser in Timken, the counterweights
and other cooling bed components did not perform other functions during fan
servicing and maintenance.”). So in sum, under this interpretation, a “machine” is
made up of components that serve no other purpose besides the one they
accomplish together when operating simultaneously.
These observations by the Secretary amount to “agency action” to clarify the
scope of the LOTO standard.4 See Martin, 499 U.S. at 157. In making them, the
Secretary made clear he was not merely disputing the ALJ’s version of the facts;
he argued that “[r]ejecting the ALJ’s approach” to interpreting the regulation was
“essential to preserving a meaningful distinction between a single integrated
system[] and machinery and equipment that truly operate independently.” Id. at
11.
4
In his initial brief, the Secretary takes the position that two pieces of equipment form a
“machine” for the purposes of the LOTO standard “if they are permanently interconnected in a
single integrated system and neither can serve its intended function without the other.”
Secretary’s Initial Br. at 16. Although the Secretary characterizes this particular test for whether
two pieces of equipment are a “machine” as “longstanding,” there is no indication in the record
that the Secretary has used this particular language in any administrative adjudication or other
formal or informal guidance. We owe no deference to an interpretation of the law advanced for
the first time before this Court. See Martin, 499 U.S. at 156. Nevertheless, as we explained
above, we think the Secretary made various statements articulating a very similar interpretation
of the LOTO standard during administrative proceedings below. Those statements during the
administrative adjudication process are the focus of our analysis.
15
Case: 16-15792 Date Filed: 07/13/2017 Page: 16 of 24
This new interpretation of the LOTO standard deserves deference if
reasonable. But the ALJ—and by extension, the Commission—failed to address
the Secretary’s precise distinction at all. The ALJ analyzed only whether the fans
and counterweights could function mechanically without the other, i.e., whether
each could be turned on and off independently. By adopting the ALJ’s decision,
the Commission thus failed to consider the Secretary’s more precise question:
whether the fans and counterweights each served any purpose in isolation while the
other equipment was inactive. The Commission should have analyzed whether this
was a reasonable way to determine if two pieces of equipment “function[ed]
independently” for LOTO purposes. We now address this question.
Having carefully considered the Secretary’s test for whether some
equipment functions independently from other equipment—and thus constitutes a
distinct “machine”—we find it to be reasonable. We note that
the Secretary’s interpretation is not undeserving of
deference merely because the Secretary advances it for
the first time in an administrative adjudication.
But . . . the decision to use a citation as the initial means
for announcing a particular interpretation may bear on
the adequacy of notice to regulated parties, on the quality
of the Secretary’s elaboration of pertinent policy
considerations, and on other factors relevant to the
reasonableness of the Secretary’s exercise of delegated
lawmaking powers.
16
Case: 16-15792 Date Filed: 07/13/2017 Page: 17 of 24
Martin, 499 U.S. at 158 (citations omitted). We conclude the Secretary’s
interpretation is in line with the goals of the Act and accompanying regulations,
and regulated parties had adequate notice of this interpretation.
The Act’s purpose is straightforward: “‘to assure so far as possible safe and
healthful working conditions’ for ‘every working man and woman in the Nation.’”
Georgia Pac. Corp. v. Occupational Safety & Health Review Comm’n, 25 F.3d
999, 1004 (11th Cir. 1994) (quoting 29 U.S.C. § 651(b)). The LOTO standard
serves that goal by requiring employers to “disable machines or equipment to
prevent unexpected energization, start-up or release of stored energy in order to
prevent injury to employees.” 29 C.F.R. § 1910.147(a)(3)(i). As a single
mechanical system grows more complex, the risk of injury the system poses for
employees servicing its components grows or becomes more uncertain. To
consider a single complex mechanical system a “machine” under the LOTO
regulation—even if its components are not tightly and permanently connected—
accomplishes the central purpose of the regulation, which is to minimize
foreseeable harms arising from energized machinery. Because the Secretary’s
interpretation covers equipment that poses a serious, foreseeable risk to employees
whenever they fail to lock it out, we conclude that the interpretation “sensibly
conforms to the purpose and wording of the regulations.” Martin, 499 U.S. at 151
(internal quotation marks omitted).
17
Case: 16-15792 Date Filed: 07/13/2017 Page: 18 of 24
That being said, we do not think the Secretary’s interpretation to be so broad
that employers lack sufficient notice of their obligations. In advancing this
interpretation, the Secretary has further clarified, rather than departed from, the
guidance he has already provided. Employers were already aware, in light of the
LOTO Directive, that the Secretary intended to enforce the LOTO standard in
cases where injurious machinery did not “function[] independently” of machinery
being serviced. In light of this guidance, it is reasonable to maintain LOTO
protocols reflective of the various dangers that a complex mechanical system could
create, regardless of whether different parts of that system could be powered on
and off independently.
Indeed, Gerdau’s protocols called for the entire cooling bed to be locked out
whenever technicians serviced any part of the bed. In the words of the Gerdau
technician responsible for locking out the cooling bed,
The reason for locking out the entire equipment is
accidents. Going in and out, you will have to cross
different pieces of equipment, plus once you’re working
on a certain piece of equipment, they overlap so much
that you can’t work on one specific piece without locking
out other equipment as well.
H’rg Tr. at 322-23, Action Electric Co., 25 BNA OSHC 2138 (No. 12-1496, 2013)
(ALJ). This type of judgment is intuitive to a technician familiar with the
machinery for which he is responsible. Equally intuitive is the judgment that
18
Case: 16-15792 Date Filed: 07/13/2017 Page: 19 of 24
Gerdau need not shut down its entire factory to ensure safety during servicing of
the cooling bed alone.
We therefore disagree with one Commissioner’s concern that, under the
Secretary’s interpretation, “it is impossible to discern where a machine begins and
ends,” with the result that an employer might be required to lock out its entire
factory to perform any maintenance at all. See Commission Decision, 2016 WL
3747113, at *15. It is hard to imagine employers locking out machinery that poses
no foreseeable risk whatsoever to technicians servicing other equipment—perhaps
due to the lack of any physical proximity—simply for fear of a reviewing court’s
convoluted theory that the two constitute a single machine because they are both
part of an overall production process. Any such application of the LOTO standard
undoubtedly would be considered unreasonable.
But we also think the Secretary’s interpretation is well-enough defined to
give employers adequate notice of their responsibilities from this point forward.
The defining question is whether equipment being serviced has any purpose apart
from its simultaneous operation with equipment creating danger from unexpected
energization or release of stored energy, and vice versa. Here, Gerdau’s cooling
bed can perform a useful task in the production process—cooling steel billets—
even if other parts of the production process are inactive. That is, the various
19
Case: 16-15792 Date Filed: 07/13/2017 Page: 20 of 24
production processes within one steel mill need not be active simultaneously to
achieve progress in production. So the cooling bed is one “machine.”
In contrast, neither the fans nor the counterweights serve any purpose at all
if the other is inactive. If the counterweights move without active fans, then the
steel billets simply move without being cooled. If the fans are active without the
counterweights moving, then the steel billets are not cooled as intended. Neither
the fans nor the counterweights can perform useful work in isolation. So the
counterweights and fans are not independent “machines” but are rather sub-
systems of the same “machine.” Employers can apply this analysis reliably
anytime they are servicing a particular piece of equipment and must decide which
other equipment to lock out to comply with the LOTO standard.
In sum, we think employers, who must make frequent and expert judgments
about workplace safety to quell the regulatory and liability concerns they face, are
capable of determining the appropriate scope of their LOTO protocols. This is true
particularly now that the Secretary has explained with more granularity which
complex mechanical systems will be considered one “machine.” Accordingly, we
hold that the interpretation of the LOTO standard offered by the Secretary in
administrative proceedings below is reasonable.
The Commission’s final decision failed to address, much less apply, this
reasonable interpretation. Under this interpretation, Gerdau’s cooling bed is one

“machine,” and the LOTO regulation required lockout of its counterweights while
its fans were being serviced.
B.
We now decide whether the Action employees were “servicing” or
performing “maintenance” on the cooling bed at the time of the accident. See 29
C.F.R. § 1910.147(a)(2)(i). We conclude that the LOTO standard applied to the
Action employees’ activities because they were workplace activities directed at the
cooling bed that exposed the employees to the release of hazardous energy from
the cooling bed.
The LOTO regulation defines “servicing and/or maintenance” as
“[w]orkplace activities such as constructing, installing, setting up, adjusting,
inspecting, modifying, and maintaining and/or servicing machines or equipment.”
29 C.F.R. § 1910.147(b). The regulation then clarifies that “[t]hese activities
include lubrication, cleaning or unjamming of machines or equipment and making
adjustments or tool changes, where the employee may be exposed to the
unexpected energization or startup of the equipment or release of hazardous
energy.” Id.
During administrative proceedings below, the Secretary took the position
that the Action employees’ observation of the fans qualified as both “setting up”
and “inspecting” under the meaning of the regulation. ALJ Br. at 17-20; see 29
21
Case: 16-15792 Date Filed: 07/13/2017 Page: 22 of 24
C.F.R. § 1910.147(b) (defining “[s]etting up” as “[a]ny work performed to prepare
a machine or equipment to perform its normal production operation”). We agree,
but we do not think this issue necessarily turns on the definition of each of the
examples of “[w]orkplace activities” enumerated in the regulation. The clear
thrust of the regulation is broadly to ensure safety where an employee performs
legitimate workplace activities directed at the relevant machine and “where the
employee may be exposed to the unexpected energization or startup of the
equipment or release of hazardous energy.” See 29 C.F.R. § 1910.147(b) (listing
examples of workplace activities using the phrase “such as”); Otis Elevator Co. v.
Sec’y of Labor, 762 F.3d 116, 123 (D.C. Cir. 2014) (finding the application of the
LOTO standard to “unjamming” work to be expressly contemplated by the text of
the regulation but also broadly in line “with the standard’s preventative purpose”).
The Action employees’ activities easily fall into this category. According to
undisputed testimony, the employees were observing the cooling-bed fans to
decide which fans were going to be replaced and where to begin working. No
matter whether this activity was “inspecting,” “setting up,” or something else
productive, it was the kind of workplace activity that the regulation sought to cover
22
Case: 16-15792 Date Filed: 07/13/2017 Page: 23 of 24
because it was directed at the relevant machine and exposed the employees to the
release of hazardous energy outside of normal production operations.5
Although Action argues that the “employees were simply looking at the fans
from 7 or 8 feet away, trying to determine what they were going to do,” this
statement effectively acknowledges that the employees were engaged in a work-
related activity that facilitated further maintenance. See Action’s Br. at 19-20. As
far as we can tell, the purpose of the definition given for “servicing and/or
maintenance” is not to carve out a narrow set of activities deserving of the
protection of the LOTO standard; it is to make clear that the regulation applies to
legitimate work-related activities directed at a given machine that expose an
employee to the release of hazardous energy from that machine outside of normal
production operations. Accordingly, we conclude that the LOTO standard applied
to the Action employees’ observation of the cooling-bed fans.
V.
For these reasons, the Secretary’s petition for review is GRANTED. We
VACATE the ruling of the Commission adopting the ALJ’s decision and
5
The ALJ concluded that the Action employees were not servicing the fans because they
were not exposed to the unexpected energization of or release of hazardous energy from the fans
themselves (as opposed to from the “machine”). See ALJ Decision & Order at 12. Because we
conclude today that the relevant “machine” for the purposes of applying the LOTO standard is
the entire cooling bed, this finding by the ALJ cannot support its conclusion that the employees
were not engaging in “servicing and/or maintenance.”
