This opinion is uncorrected and subject to revision before publication in the New York Reports.
The issue before us is whether vicarious liability under Labor Law § 241 (6) may be predicated solely on a violation of regulations contained in part 12 of the Industrial Code. We conclude that it may not.
During the 1970s and 1980s, decedent Donald Nostrom worked as a boilermaker for subcontractors on construction projects at various energy facilities, including those owned by defendants Orange & Rockland Utilities, Inc. (O&R) and Central Hudson Gas & Electric Corp. According to Nostrom, defendant Sequoia Ventures, Inc., f/k/a Bechtel Corporation, served as the general contractor for two of the projects. While working at these power plants, Nostrom was allegedly exposed to asbestos through airborne dust and contact with asbestos-containing materials. He subsequently contracted mesothelioma.
Nostrom and his wife, suing derivatively, commenced this action against more than 60 defendants, including O&R, Central Hudson and Sequoia.*fn1 As relevant here, Nostrom asserted a Labor Law § 200 claim against Central Hudson and a violation of Labor Law § 241 (6) against each of the three defendants involved in this appeal. The section 241 (6) claim was premised on violations of Industrial Code (12 NYCRR) part 12 regulations, which require the prevention of air contamination (12 NYCRR 12-1.4 [b] , ) and the removal of dangerous air contaminants (12 NYCRR 12-1.6 [a]). After discovery, defendants separately moved for summary judgment dismissing the complaint.*fn2
Supreme Court granted the motions and dismissed the complaint insofar as asserted against defendants. Nostrom appealed the dismissal of the Labor Law § 241 (6) cause of action and the Appellate Division affirmed, reasoning that a violation of regulations from part 12 of the Industrial Code cannot sustain a section 241 (6) claim (59 AD3d 159 [1st Dept 2009]). Alternatively, the Appellate Division concluded that the two regulations invoked by Nostrom were not "sufficiently specific to support a section 241 (6) claim for asbestos-related injury" (id. at 160). We granted Nostrom leave to appeal (13 NY3d 880 ).*fn3
Because defendants did not direct or control decedent's work, they can be liable only if Labor Law § 241 (6) applies, imposing vicarious liability on owners and contractors for the conduct of others. Section 241 (6) provides:
"All areas in which construction, excavation or demolition work is being performed shall be so constructed, shored, equipped, guarded, arranged, operated and conducted as to provide reasonable and adequate protection and safety to the persons employed therein or lawfully frequenting such places. The commissioner may make rules to carry into effect the provisions of this subdivision, and the owners and contractors and their agents for such work, except owners of one and two-family dwellings who contract for but do not direct or control the work, shall comply therewith."
The second sentence of this provision, requiring owners and contractors to comply with the Commissioner of Labor's rules, creates a nondelegable duty "where the regulation in question contains a specific, positive command" (Morris v Pavarini Constr., 9 NY3d 47, 50  [internal quotation marks and citation omitted]). At issue is whether the section 241 (6) claim in this case may be based on the violation of Industrial Code part 12 regulations pertaining to the control of air contaminants in the workplace.
Nostrom argues that sufficiently specific regulations are set forth in part 12 of the Industrial Code and, like those found in part 23, these may be invoked to impose vicarious liability under Labor Law § 241 (6). Consequently, she asserts that O&R and Central Hudson, as owners, and Sequoia, as a general contractor, may be held liable for the alleged failures of various subcontractors to comply with sections 12-1.4 (b) and 12-1.6 (a) of the Code. Defendants respond that the Appellate Division correctly held that the relevant language and history underlying these regulations demonstrate that part 12 cannot support vicarious liability except to the extent that part 12 regulations are specifically incorporated into part 23.
In matters of statutory and regulatory interpretation, "legislative intent is the great and controlling principle, and the proper judicial function is to discern and apply the will of the enactors" (Matter of ATM One v Landaverde, 2 NY3d 472, 477  [internal quotation marks and citation omitted]). As we have noted, the text of a provision is the clearest indicator of the enactors' intent, "and courts should construe unambiguous language to give effect to its plain meaning" (Matter of DaimlerChrysler Corp. v Spitzer, 7 NY3d 653, 660 ). Additionally, inquiry should be made into "the spirit and purpose of the legislation, which requires examination of the statutory context of the provision as well as its legislative history" (Landaverde, 2 NY3d at 477 [internal quotation marks and citation omitted]).
Part 23 of the Industrial Code governs the protection of workers in construction, demolition and excavation operations. Its "Application" provision expressly states that the rules in part 23 apply to "owners, contractors and their agents obligated by the Labor Law to provide such persons with safe working conditions and safe places to work" (12 NYCRR 23-1.3). Hence, it is clear that part 23 was promulgated pursuant to the authority granted by Labor Law § 241 (6) and that owners and contractors may be vicariously liable based on violations of part 23 regulations.*fn4 In contrast, the "Application" section of part 12 does not specify that its rules apply to owners, contractors and their agents. The absence of such wording suggests that part 12 was not created to give effect to the provisions of section 241 (6) and indicates an intent not to impose vicarious liability in connection with part 12 regulations.
Furthermore, the language of 12 NYCRR 23-1.7 (g) confirms that part 12 regulations, by themselves, were not intended to serve as a predicate for liability under Labor Law § 241 (6). Section 23-1.7 (g) makes any "unventilated confined area" where dangerous air contaminants may be present subject to the provisions of part 12. By incorporating the requirements of part 12 into this narrow subset of work sites governed by part 23 -- unventilated confined areas -- it is evident that the intent was to impose a nondelegable duty on owners and contractors in these limited circumstances. Consequently, a plaintiff may bring a section 241 (6) claim based on a violation of a part 12 rule only where the injury occurred in an unventilated confined area, thereby triggering section 23-1.7 (g)'s "pass-through" provision (see Rivera v Ambassador Fuel & Oil Burner Corp., 45 AD3d 275 [1st Dept 2007]).*fn5 Accepting Nostrom's position that vicarious liability may be grounded on a part 12 violation regardless of the location of the exposure would render section 23-1.7 (g) superfluous. And a construction that "renders one part meaningless should be avoided" (Rocovich v Consolidated Edison Co., 78 NY2d 509, 515 ).
Our conclusion that part 12 does not impose liability on owners and contractors under Labor Law § 241 (6), except insofar as it is expressly incorporated into part 23, is consistent with the regulatory history underlying the two parts. Industrial Code Bulletin No. 23, part 23's predecessor, was adopted by the State Industrial Commission in 1920. In 1941, the Board of Standards and Appeals replaced the original regulations with a new part 23, specifically referencing the rule-making authority vested in the Board by Labor Law § 241. The Board again invoked section 241 when it revised part 23 in 1963. Although the Board did not refer to section 241 when it completed its most recent substantive changes to part 23 in 1972, it is clear that part 23 continues to implement the authority granted by the Legislature under section 241 (6) because it explicitly applies to owners, contractors and their agents (see 12 NYCRR 23-1.3). On the other hand, although part 12's predecessor was redesignated as part 12 in 1954 and was thereafter substantially revised in 1956, 1961 and 1971, the Board did not cite section 241 as a basis for these enactments.
In short, the language and history of the relevant provisions establish that part 12 regulations do not provide a basis for liability under Labor Law § 241 (6) except to the extent that particular regulations are specifically incorporated into part 23. As a result, the Appellate Division correctly affirmed the dismissal of Nostrom's section 241 (6) claim, which was predicated solely on alleged violations of 12 NYCRR 12-1.4 (b) and 12 NYCRR 12-1.6 (a). We therefore need not reach the Appellate Division's alternative ...
