The Secretary of Labor petitions for review of an order of the Occupational Safety and Health Review Commission (“Commission”) vacating a citation imposed by the Secretary of Labor under 29 C.F.R. § 1926.105(a) against Williams Enterprises of Georgia, Inc. (“Williams”). We reverse the Commission.
I
Williams is a steel erection company engaged in the construction of a high rise office tower in Atlanta. During an inspection of the construction site, an Occupational Safety and Health Administration (“OSHA”) compliance officer determined that the structure lacked adequate safety devices. Specifically, he found that Williams failed to provide safety nets to protect against exterior falls by its workers installing the steel beams for the fifth, sixth and seventh floors of the structure. Consequently, OSHA issued a citation to Williams alleging a “serious violation” 1 of Section 1926.105(a). 2 Williams contested the citation, but an Administrative Law Judge (“AU”) affirmed the imposition of the citation. The Commission granted Williams’ petition for review and reversed the AU’s decision, thereby vacating the citation. In its opinion, the Commission decided that Section 1926.105(a) did not apply to Williams because Subpart R, 29 C.F.R. §§ 1926.750-52, provided the exclusive safety regulations for the steel erection industry. The Secretary then properly noticed this appeal from the Commission’s decision under 29 U.S.C.A. § 660(b).

A
The central issue in this case is whether the regulations contained in Subpart R, which provide specific safety standards for the steel erection industry, preempt the safety regulations generally applicable to the entire construction industry. The Secretary maintains that, although the regulations in Subpart R preempt some of the safety regulations generally applicable to the construction industry, they do not preempt the application of Section 1926.-105(a) because they do not contain any provision relating to exterior falls from perimeter beams. The Commission, on the other hand, contends that Subpart R was intended to provide comprehensive regulations for the steel erection industry and that, because Subpart R lacks any provision addressing exterior falls from perimeter beams, Williams cannot be required to install exterior safety nets. 3
Because the Secretary of Labor promulgates the regulations
4
under the Occupational Safety and Health Act of 1970, 29 U.S.C.A. §§ 651-78, his reasonable interpretation of those regulations is controlling, even though his interpretation
In the present case, the Secretary’s interpretation is reasonable. It is also consistent with 29 C.F.R. § 1910.5(c), which explains how to apply the Secretary’s standards. That section provides:
(c)(1) If a particular standard is specifically applicable to a condition, practice, means, method, operation or process, it shall prevail over any different general standard which might otherwise be applicable to the same condition, practice, means, method, operation or process.... (c)(2) On the other hand, any standard shall apply according to its terms to any employment and place of employment, in any industry, even though particular standards are also prescribed for that industry, as in Subpart B or Subpart R of this part, to the extent that none of such particular standards applies.
Courts have interpreted the expression “condition, practice, means, method, operation or process” as referring to the kind of hazard in question.
See, e.g., Donovan v. Daniel Marr & Son,
The only regulations in Subpart R that might conceivably apply to exterior falls from perimeter beams are Sections 1926.750(b)(l)(ii) and (2)(i) 5 which provide:
(b)(l)(ii) On buildings or structures not adaptable to temporary floors, and where scaffolds are not used, safety nets shall be installed and maintained whenever the potential fall distance exceeds two stories or 25 feet....
(b)(2)(i) Where skeleton steel erection is being done, a tightly planked and substantial floor shall be maintained within two stories or 30 feet, whichever is less, below and directly under that portion of each tier of beams on which any work is being performed.... Where such a floor is not practicable, paragraph (b)(l)(ii) of this section applies.
Because these standards are not expressly limited to falls toward the interior part of a building, they might be read as requiring exterior safety nets as well. However, Section 1926.750(b) is satisfied if the structure has temporary floors, and temporary
Three circuits have embraced this interpretation of Section 1926.750(b) and have held that Section 1926.105(a) applies to the steel erector industry.
Brock v. L.R. Willson & Sons,
To refute this argument, Williams asserts that the Secretary’s original intent in adopting Subpart R was to eliminate any protection for exterior falls from perimeter beams. However, there is no support for this argument in the promulgating language. In addition, such an intent would certainly be contrary to the Secretary’s duty to “promulgate the standard which assures the greatest protection of the safety or health of the affected employees.” 29 U.S.C.A. § 655(a). “It must be presumed that the Secretary acted in accordance with this statutory mandate and did not adopt Subpart R with the purpose of diminishing the level of security provided by the general fall protection standards.”
Adams Steel,
Williams also argues that the Secretary has espoused a contrary interpretation in other lawsuits and in recent proposed regulations. The only case which Williams alleges demonstrates the Secretary’s contrary interpretation is
Brock v. Cardinal Indus.,
Finally, Williams contends that the Secretary conceded in a Notice of Proposed Rule Making that Subpart R provides comprehensive safety regulations for the steel erection industry. Williams’ argument is based on the fact that the Notice stated that the general construction industry fall standards, including Section 1926.105(a), would be incorporated into Subpart M,

42718, 42724 (1986), while the fall standards for the steel erection industry would remain in Subpart R.

B.
Williams next argues that application of the Secretary’s interpretation violates due process because Williams did not have fair notice of the requirements of Section 1926.-105(a). This argument encompasses two potential claims. The first contention is that Section 1926.105(a) fails to provide adequate notice because it is too vague, either on its face or in conjunction with Section 1926.750(b). The second contention is that Williams was deprived of adequate notice by the Secretary’s failure to apply his interpretation of Section 1926.105(a) to the steel erection industry in the face of widespread industry non-compliance. We reject both of these claims.
Due process mandates that an employer receive notice of the requirements of any OSHA regulation before he is cited for an alleged violation.
S & H Riggers,
Similarly, there is no merit to the suggestion that widespread industry non-compliance means that Williams did not have fair notice of the instant regulation. Courts have rejected the notion that an employer lacks notice of an OSHA regulation when the Secretary fails to prosecute violations of that regulation widely.
See, e.g., Willson III,
C.
The next contention Williams raises is that, even if Section 1926.105(a) applies here, the Secretary has not proven a violation of that section. The Secretary bears the burden of proving every element of a violation. 29 C.F.R. § 2200.73;
B & B Insulation,
These facts establish a violation of Section 1926.105(a). The workers installing
Williams attempts to avoid this result by asserting that its failure to install exterior safety nets did not violate Section 1926.105(a) because it installed temporary floors, which is an alternative safety device listed in that section. As support for this contention, Williams cites two cases which held that safety nets were not required when employees were working on temporary flooring or scaffolding.
Brennan v. OSHRC and Ron M. Fiegen, Inc.,
In the present case, there is substantial evidence in the record from which only one conclusion can be drawn. Accordingly, the Secretary’s citation must be reinstated.
D.
Williams’ final argument is that, if this Court determines that the Secretary established a violation of Section 1926.105(a), this case must be remanded to the Commission for consideration of Williams’ affirmative defenses. At the hearing before the AU, Williams argued that installing safety nets would be impossible. In addition, it asserted that res judicata and collateral estoppel barred the Secretary from enforcing the OSHA standards because the issue of whether Section 1926.105(a) was applicable to steel erectors had been tried and lost by the Secretary in previous cases involving Williams. See, e.g., Williams Enterprises of Georgia, Inc., 5 O.S.H.Cas. (BNA) 2050 (Rev.Comm’n 1977). Although the AU rejected all of these defenses, the Commission did not rule on any of them. Instead, its decision rested solely on the ground that Subpart R preempted Section 1926.105(a). Consequently, Williams contends that a remand is necessary so that the Commission can review the affirmative defenses. We disagree.
A remand is unnecessary because this Court can determine that Williams is not entitled to prevail on any of its defenses.
See Willson III,
Second, this action is not barred on account of res judicata because it does not present the same facts or same cause of action as any previous citation issued by the Secretary against Williams. Thus, one of the prerequisites of res judicata is not satisfied.
Stevenson v. International Paper Co.,
In addition, collateral estoppel does not apply even though the Secretary may have failed to prevail on this legal issue in a previous proceeding against Williams. Collateral estoppel is a discretionary doctrine that has no application where there has been an intervening change in legal principles.
See Parnell v. Rapides Parish School Bd.,
Ill
In conclusion, because the Secretary’s interpretation of Section 1926.105(a) is reasonable, we REVERSE the Commission and hold that the Secretary has established a violation of that section. We direct the Commission to reinstate the citation of the Secretary. Remand to the Commission for consideration of Williams’ affirmative defenses is unnecessary because we find these defenses to be without merit.
Notes
. A serious violation is defined as one of which the employer was aware, or reasonably should have been aware, and which creates a substantial probability of death or serious bodily injury. 29 U.S.C.A. § 666(k).
. Section 1926.105(a) provides:
Safety nets shall be provided when work places are more than 25 feet above the ground or water surface, or other surfaces where the use of ladders, scaffolds, catch platforms, temporary floors, safety lines, or safety belts is impractical.
. The Commission formerly held that Subpart R did not preempt Section 1926.105(a) with respect to exterior fall hazards in the steel erection industry.

Williams Enterprises, Inc.,
.The Secretary’s authority to promulgate OSHA standards is contained in 29 U.S.C.A. § 655.
. Section 1926.750(b)(l)(iii) provides that a safety railing of wire rope shall be installed around the periphery of all temporary-planked floors of tier buildings. Although this regulation protects against exterior falls from temporary floors, it does not provide any protection against falls from perimeter beams or from newly built levels where temporary floors have not been con-strutted. Thus, this section does not even arguably apply to exterior falls from perimeter beams above the temporary floors. By its own terms, this section fails to preempt Section 1926.105(a) because it does not address the danger with which Section 1926.105(a) is concerned.
