Methylenedianiline requirements

Yes. The methylenedianiline requirements that apply to shipyard employment under 1915.1050 are identical to the requirements set forth at 1910.1050 for general industry, so shipyard employers must comply with the same provisions as general industry employers.

Look to 1910.1050 for the full text and details because 1915.1050 states that the shipyard requirements are identical to the provisions in 1910.1050.

Yes. Because 1915.1050 makes the shipyard requirements identical to 1910.1050, shipyard employers must meet the exposure limits and control measures contained in 1910.1050.

All employers engaged in shipyard employment where methylenedianiline hazards are present must comply with the standard; 1915.1050 directs shipyard employers to meet the identical requirements in 1910.1050.

Yes. The 1915.1050 entry notes its Federal Register history: 58 FR 35701 (July 1, 1993), 61 FR 5507 (Feb. 13, 1996), and 61 FR 31427 (June 20, 1996), which record publication and amendment actions related to the standard.

The official electronic version is available through the e-CFR link shown in the standard metadata; see 1915.1050 which cites the e-CFR as its GPO source.

Yes. Use 1910.1050 as the compliance checklist because 1915.1050 makes the shipyard requirements identical to the general industry rule.

Yes. States with OSHA-approved State plans must have standards and enforcement programs at least as effective as federal OSHA, and they may be more stringent; employers should check their State-plan agency for any additional or differing methylenedianiline requirements (see discussion of State plans in OSHA interpretations such as Scope of rim wheel servicing).

Yes—OSHA letters of interpretation can explain how OSHA interprets a standard, but they do not create new obligations beyond the regulation; for example, OSHA letters consistently state that interpretation letters explain requirements but do not add obligations (see OSHA letters such as Head protection for crane operators). Always follow the language of 1915.1050 and 1910.1050 first, and use interpretation letters for clarification.

No additional regulatory text is required simply because the work is in a shipyard; 1915.1050 makes the shipyard requirements identical to 1910.1050, so compliance with 1910.1050 satisfies the shipyard requirement, subject to any applicable State-plan variations.

For federal enforcement or clarification, consult OSHA and the text of 1915.1050 together with 1910.1050; for state-specific issues, contact your OSHA-approved State-plan agency as state plans may have different enforcement guidance (see the state-plan discussion in OSHA interpretation Scope of rim wheel servicing).
