Questions & Answers

Under 1915.1003, which OSHA rule applies to the "13 carcinogens" listed for shipyard employment?

Yes — shipyard employers must follow the same requirements as the general industry rule at 1910.1003. The shipyard rule 1915.1003 states explicitly that the requirements applicable to shipyard employment are identical to 1910.1003.

Under 1915.1003, where can I find the official list and requirements for the 13 carcinogens (for example, 4‑Nitrobiphenyl)?

The official list and the compliance requirements are in 1910.1003, which 1915.1003 adopts for shipyard employment. Consult 1910.1003 for the exact names of the 13 carcinogens and the specific employer duties.

Under 1915.1003, do shipyard employers need to perform exposure monitoring for the listed carcinogens?

Yes — shipyard employers must follow the exposure-monitoring requirements set out in 1910.1003. Because 1915.1003 is identical to 1910.1003, any monitoring, initial or periodic, required by the general industry rule also applies in shipyards.

Under 1915.1003, are regulated areas required when exposures to any of the 13 carcinogens exceed limits?

Yes — requirements for establishing regulated areas are those in 1910.1003. Because 1915.1003 adopts 1910.1003, shipyard employers must establish regulated areas if the conditions in 1910.1003 require them (for example, where engineering and work-practice controls cannot keep exposures below required limits).

Under 1915.1003, must shipyard employers provide medical surveillance for workers exposed to these carcinogens?

Yes — medical surveillance requirements that appear in 1910.1003 apply to shipyards through 1915.1003. Follow the timing, content, and access-to-results rules in 1910.1003 for any employee meeting the exposure criteria there.

Under 1915.1003, do the 13 carcinogens have occupational exposure limits I must follow?

Yes — any permissible exposure limits, action levels, or other numerical limits for the 13 carcinogens are those set in 1910.1003. The shipyard rule 1915.1003 makes the 1910.1003 limits binding for shipyard employment.

Under 1915.1003, are employers required to provide training and information about the 13 carcinogens to shipyard workers?

Yes — training and employee information obligations are those in 1910.1003, and they apply in shipyards via 1915.1003. Shipyard employers must give the required hazard communication, training on protective measures, and access to any required materials as described in 1910.1003.

Under 1915.1003, if I have an operation on a vessel that uses one of the 13 carcinogens, which standard controls — engineering, administrative, or PPE — apply?

You must follow the hierarchy and specific control requirements set in 1910.1003; 1915.1003 adopts those same requirements for shipyard employment. That means you must implement feasible engineering and work-practice controls first to reduce exposures, and use personal protective equipment where controls alone do not adequately protect employees, as specified in 1910.1003.

Under 1915.1003, do the recordkeeping and employee exposure records for the carcinogens follow the same retention rules as in general industry?

Yes — recordkeeping rules that appear in 1910.1003 apply to shipyard employers through 1915.1003. Keep exposure measurements, medical surveillance records, and related employee-access records according to the timelines and procedures in 1910.1003.

Under 1915.1003, are labels and warning signs required for materials that contain any of the 13 carcinogens?

Yes — labeling and warning sign requirements applicable to the 13 carcinogens are those in 1910.1003, and they apply in shipyards per 1915.1003. Use the labeling, marking, and regulated-area signage prescribed in 1910.1003 where required.

Under 1915.1003, do contractors working in shipyards have to follow the carcinogen rules when they bring materials or do tasks involving these substances?

Yes — contractors working on shipyard sites must follow the same requirements in 1910.1003 because 1915.1003 makes the general industry rule applicable in shipyards. Employers controlling work or bringing hazardous materials onto a shipyard are responsible for complying with the applicable provisions of 1910.1003.

Under 1915.1003, if a shipyard has inconsistent rules between a vessel owner and a contractor, which requirements control for the 13 carcinogens?

Shipyard employers must comply with the legal obligations in 1910.1003, as adopted by 1915.1003. Contractual agreements do not override OSHA duties; the employer(s) responsible for the work must meet the 1910.1003 requirements regardless of private arrangements.

Under 1915.1003, are the enforcement and citation policies for these carcinogens the same as under general industry standards?

Yes — enforcement follows the same standards and citation policies that apply to 1910.1003, since 1915.1003 adopts those requirements verbatim for shipyards. Inspectors will evaluate compliance based on the requirements in 1910.1003.

Under 1915.1003, where can I read the official shipyard text that explains these rules are identical to the general industry standard?

The shipyard rule itself states the identity: see 1915.1003, which notes that "the requirements applicable to shipyard employment under this section are identical to those set forth at 1910.1003." For the full compliance provisions, read 1910.1003.

Under 1915.1003, does OSHA provide any shipyard‑specific guidance beyond the general industry text for the 13 carcinogens?

No — 1915.1003 makes the shipyard requirements identical to 1910.1003 and does not add different shipyard‑specific provisions. Any additional guidance would come from OSHA interpretations or enforcement letters that reference the standard; for the regulatory obligations, use 1910.1003.

Under 1915.1003, if the work is performed aboard a vessel where maritime law applies, does OSHA’s adoption of 1910.1003 still apply?

Yes for civilian shore‑based shipyard employment — 1915.1003 applies OSHA's shipyard standards when OSHA has jurisdiction. However, OSHA coverage can be affected by special maritime or federal exclusions in particular circumstances; consult OSHA jurisdiction guidance and apply the 1910.1003 requirements where OSHA applies. See 1915.1003 for the linkage to 1910.1003.

Under 1915.1003, who should I contact for clarifications about how the general industry provisions apply in a specific shipyard situation?

For clarification, contact OSHA regional or area offices and refer to 1915.1003 and 1910.1003 when describing your scenario. The rules in 1915.1003 point you to 1910.1003 for the substantive requirements; OSHA regional staff can provide interpretation and enforcement guidance.

Under 1915.1003, are shipyard employers required to follow any updated changes to 1910.1003 when OSHA revises the general industry rule?

Yes — because 1915.1003 ties shipyard requirements to 1910.1003, any final regulatory changes to 1910.1003 that become effective will apply to shipyard employment under 1915.1003 unless OSHA or the rule language provides otherwise.
