Material Safety Data Sheets (M.S.D.S.) are responsible to be furnished and updated by the

• A. The workers
• B. The employer
• C. The safety committee
• D. The supplier

Answer: (B)

The main idea is who must provide and keep up-to-date information on hazardous chemicals for workers. Under hazard communication rules, the employer is responsible for ensuring that employees have access to the Safety Data Sheets (SDS) for chemicals used on the job and for keeping those sheets current. The supplier or manufacturer provides the initial SDS to the employer when a chemical is purchased and supplies updates or revised sheets. It’s the employer’s duty to distribute the current SDS to workers and replace older versions so training and safety practices reflect the latest information. So, while the supplier furnishes the SDS and its updates, the ongoing obligation to furnish to employees and maintain current sheets in the workplace rests with the employer.
