According to OSHA CFR 29 1910, what is the order to address sound exposure?

• A. Applying engineering controls, then administrative controls, and then PPE
• B. PPE first, then engineering controls, then administrative controls
• C. Administrative controls, then PPE, then engineering controls
• D. Engineering controls only

Answer: (A)

The way OSHA addresses sound exposure is to tackle it with controls in a specific order: first use engineering controls to reduce or quiet the noise at its source or along its path, then apply administrative controls to shorten workers’ exposure time, and only after those steps provide hearing protection as a last resort. This sequence minimizes exposure without relying on PPE alone. If noise is still above limits after engineering and administrative measures, PPE is added to protect the worker. So the best approach follows engineering controls, then administrative controls, and finally PPE. The other options would either place PPE too early, rely on fewer-than-necessary measures, or omit essential steps.
