Subpart Z
The rule applies to any shipyard activity that uses, stores, manufactures, handles, or moves 4‑Dimethylaminoazobenzene on the employer's premises. 1915.1015 states that the shipyard requirements are identical to those in 1910.1003, so any operation covered by 1910.1003 is covered in shipyard employment as well.
Employers must give employees information and training about the hazards of 4‑Dimethylaminoazobenzene and the protective measures the employer is using. The training must cover detection methods, engineered controls, safe work practices, personal protective equipment, and medical surveillance procedures as required by 1910.1003; shipyard employers follow these same requirements under 1915.1015.
Yes, employers must establish regulated areas when airborne concentrations or other hazard criteria in the standard indicate the need to restrict access to protect employees. The shipyard rule at 1915.1015 is identical to 1910.1003, which requires employers to define and control access to regulated areas to prevent unnecessary exposure.
Employers must label containers and post warning signs where 4‑Dimethylaminoazobenzene is used or stored so employees know the hazard and any special precautions. Because 1915.1015 adopts the requirements of 1910.1003, shipyard employers must provide appropriate labels and warning signs consistent with that standard.
Employers must monitor employee exposures when there is a possibility that airborne levels may exceed criteria in the standard and whenever initial monitoring shows elevated exposures. Since 1915.1015 is identical to 1910.1003, shipyard employers must conduct exposure monitoring to determine airborne concentrations and re-monitor as the standard requires.
If monitoring shows exposures above the standard's action level or permissible criteria, the employer must implement interim measures and engineering and work-practice controls to reduce exposure, provide respiratory protection if needed, and continue monitoring until exposures are controlled. 1915.1015 adopts these same requirements from 1910.1003.
Yes. Employers must offer medical examinations and surveillance to employees who are exposed above the standard's trigger levels or who develop signs or symptoms related to exposure. The shipyard provision 1915.1015 is identical to 1910.1003, so shipyard employers must follow the medical surveillance requirements in 1910.1003.
Employers must maintain medical records that include the physician's written opinions, employee medical histories, examination results, and any exposure-related test results as required by 1910.1003. Because 1915.1015 mirrors 1910.1003, shipyard employers must keep the same medical records and make them available in accordance with the standard.
Employers must implement housekeeping and hygiene practices to prevent contamination—this includes regular cleaning of work surfaces, providing handwashing facilities, prohibiting eating/drinking/smoking in contaminated areas, and controlling contaminated clothing. Since 1915.1015 adopts 1910.1003, shipyard employers must implement these hygiene and housekeeping measures.
Employers must prevent employee contact with contaminated clothing or equipment by providing laundering or disposal procedures, containment, and change areas; contaminated garments must be removed promptly and handled as potentially hazardous. Because 1915.1015 is identical to 1910.1003, shipyard employers must follow the same control and handling requirements.
Employers must have procedures for prompt cleanup of spills that protect employees—use trained personnel, proper PPE, spill controls to prevent spread, and disposal consistent with regulations. Since shipyard requirements in 1915.1015 match 1910.1003, shipyard employers must adopt and train workers on spill response procedures.
Yes. Employers must implement work-practice controls such as using closed systems where feasible, restricting access, prohibiting eating/drinking/smoking in handling areas, and cleaning procedures to minimize exposure. 1915.1015 requires shipyard employers to follow the same work-practice controls established in 1910.1003.
Before assigning a worker to a regulated area, the employer must ensure the worker has received required training, medical surveillance if applicable, and instructions on protective measures and emergency procedures as set out in 1910.1003. 1915.1015 requires shipyard employers to meet the same pre-assignment requirements.
Respirators can be used as interim or supplemental protection but not as the primary substitute for required engineering and administrative controls when those controls can reduce exposures. 1915.1015 incorporates the approach in 1910.1003, which requires employers to implement feasible engineering and work-practice controls and to provide respirators only when those controls are insufficient or during maintenance, repair, or emergencies.
Employers must ensure containers remain properly labeled and that transport routes and procedures minimize employee exposure; containers should be sealed and labeled per the standard while being moved. Since 1915.1015 is identical to 1910.1003, shipyard employers must maintain labels and safe handling during on-site movement.
An employer should review product labels, Safety Data Sheets, chemical inventory records, and supplier information to determine if 4‑Dimethylaminoazobenzene is present at levels that trigger the standard; if in doubt, exposure monitoring or chemical analysis may be needed. 1915.1015 requires shipyard employers to follow the same identification and monitoring duties stated in 1910.1003.
