1,2-dibromo-3-chloropropane requirements

Yes—1915.1044 applies to shipyard employment and adopts the same requirements as 1910.1044. The shipyard rule explicitly states that the requirements for 1,2-dibromo-3-chloropropane in shipyard employment are identical to those in 1910.1044, so shipyard employers must follow the same provisions for exposure control, monitoring, medical surveillance, training, and recordkeeping as general industry.

You must follow the specifics in 1910.1044, because 1915.1044 makes the shipyard requirements identical to that general industry standard. Review 1910.1044 for numeric exposure limits, monitoring protocols, engineering controls, and medical surveillance requirements.

Yes—shipyard employers must perform air monitoring and medical surveillance in accordance with the procedures and triggers set out in 1910.1044, because 1915.1044 states the requirements are identical. Follow the monitoring schedules, action levels, and medical exam/recordkeeping requirements detailed in 1910.1044.

Yes—contractors and temporary workers at shipyards are covered when they perform shipyard employment subject to 1915.1044. Because the shipyard rule adopts the same requirements as 1910.1044, employers (including contractors) must ensure their employees are protected by the same exposure controls, training, and medical surveillance required by the standard.

Start by checking the product label, Safety Data Sheet (SDS), and your chemical inventory; if DBCP is indicated or suspected, follow the control and notification requirements in 1910.1044 because 1915.1044 makes the shipyard requirements identical to that standard. Practical steps include:

• Obtain and review the SDS and manufacturer information.
• Include the substance in your hazard communication program and chemical inventory.
• If DBCP is present or likely, implement monitoring, engineering controls, PPE, training, and medical surveillance as required by 1910.1044.

Yes—employers must meet the warning, labeling, and area identification requirements specified in 1910.1044, because 1915.1044 adopts the same provisions for shipyard employment. Consult 1910.1044 for the exact signage text, regulated-area boundaries (if any), and label content required for containers and work areas.

Yes—if DBCP is present in the workplace, shipyard employers must include it in the hazard communication program and provide training in the hazards and protective measures in accordance with the procedures referenced in 1910.1044 and applicable 1910 requirements. Because 1915.1044 makes the shipyard requirements identical to 1910.1044, follow the training topics, frequency, and documentation practices described in 1910.1044.

Yes—shipyard employers must provide appropriate PPE when required by the exposure controls and work practices set out in 1910.1044, since 1915.1044 adopts the same requirements. Review 1910.1044 to determine the specific PPE types, selection criteria, and maintenance requirements based on monitoring results and the tasks performed.

If monitoring indicates exposures exceed the required limits, the employer must take corrective actions such as implementing or upgrading engineering controls, limiting access, providing respirators and other PPE, and enrolling affected employees in medical surveillance as specified in 1910.1044, because 1915.1044 makes the shipyard obligations identical to that standard. Follow the specific control hierarchy and timeframes in 1910.1044 for required actions and employee protection.

Yes—shipyard employers must maintain exposure monitoring and medical records consistent with the recordkeeping provisions of 1910.1044, because 1915.1044 adopts the same requirements. Review 1910.1044 for the retention periods, record contents, and employee access rights.

Yes—eliminating or substituting a hazardous chemical is an acceptable and effective compliance strategy, but any substitution must still be evaluated for hazards and implemented safely under the same program requirements referenced in 1910.1044. Because 1915.1044 adopts the 1910.1044 framework for shipyards, employers should document the substitution, verify exposures are controlled, update SDSs and the hazard communication program, and ensure employees receive training on the new chemical.

The shipyard standard includes its Federal Register citations and points to the e‑CFR source. See the 1915.1044 page for the rule title and the embedded GPO source link to e‑CFR. The section metadata on that page lists the regulatory history (e.g., 58 FR 35647, July 1, 1993, and later notices).

No—the shipyard requirements do not differ; 1915.1044 explicitly states that the requirements applicable to shipyard employment are identical to those set forth at 1910.1044. Therefore, shipyard employers should follow the same procedures, limits, and protections found in 1910.1044.

The employer controlling the shipyard worksite has primary responsibility for compliance with the DBCP requirements in 1915.1044, which adopts the same obligations as 1910.1044. That includes ensuring hazard identification, exposure monitoring, controls, training, PPE, medical surveillance, and recordkeeping are implemented for employees under the employer's control.

Begin by conducting an inventory and hazard assessment: review procurement records, SDSs, labels, and job tasks to identify any potential DBCP use. If DBCP is present or suspected, implement the monitoring, exposure control, training, and medical surveillance steps specified in 1910.1044, because 1915.1044 makes the shipyard requirements identical to that standard.

No—the DBCP requirements for shipyard employment apply equally to shipboard and shore-side shipyard operations to the extent those jobs constitute shipyard employment under 1915.1044. Because the standard adopts the requirements in 1910.1044, employers must ensure the same protections, monitoring, and recordkeeping wherever shipyard work exposes employees to DBCP.

State-plan OSHA agencies must have programs at least as effective as Federal OSHA but may adopt more stringent provisions; however, the federal 1915.1044 baseline is identical to 1910.1044. Employers in State-plan states should check the State plan for any additional shipyard-specific or chemical-specific requirements beyond the federal baseline.

For authoritative text and to determine applicable requirements, consult 1915.1044 and its counterpart 1910.1044. For interpretation or enforcement questions, contact your regional OSHA office or your State plan agency (if applicable); OSHA also posts Letters of Interpretation and enforcement memoranda on its website that may clarify how OSHA applies the standard in particular situations.
