Which action is performed by Workplace Supervisors regarding hearing conservation training?

• A. Conduct initial and annual training
• B. Approve HPDs
• C. Notify BE of changes
• D. Conduct illness investigations

Answer: (A)

The main idea here is that supervisors are responsible for delivering training to workers in a hearing conservation program. They ensure new hires receive initial training and that all employees get a periodic refresher—typically an annual update—covering why noise exposure matters, how to protect hearing, proper use and care of hearing protection devices, and the importance of audiometric testing. Supervisors are the ones in direct daily contact with the crew, so they’re best positioned to schedule these sessions, check attendance, and reinforce safe practices on the job.

Other tasks like approving hearing protection devices, notifying the Bioenvironmental Engineer of changes, or conducting illness investigations involve specialized roles or processes. Approving HPDs is handled by program administrators or safety personnel who evaluate device performance and suitability. Notifying BE of changes is an information flow task that supports program updates, and illness investigations are typically conducted by medical or EHS staff.
