Common Safety Orientation (CSO) Practice Test

Question: 1 / 400

When should a worker wear hearing protection?

In quiet environments

Whenever they feel like it

In environments where noise levels exceed safe limits

Wearing hearing protection is essential in environments where noise levels exceed safe limits due to the potential for long-term hearing damage or loss. Occupational Safety and Health Administration (OSHA) guidelines and various health safety norms indicate that when sound levels reach above a certain decibel level—typically 85 decibels—workers should use appropriate hearing protection to minimize the risk of auditory injury. This protection is crucial not only for individuals operating heavy machinery but also for any workers exposed to high noise levels, ensuring their hearing is preserved while fostering a safer work environment overall.
