Employers must train employees exposed to TWAs of 85 dB and above at least annually regarding:
- The effects of noise;
- The purpose, advantages, and disadvantages of various types of hearing protectors;
- The selection, fit, and care of protectors; and
- The purpose and procedures of audiometric testing.
The training program may be structured in any format, with different portions conducted by different individuals and at different times, as long as the required topics are covered.
