What is the action level (AL) per OSHA standards?

The action level (AL) established by OSHA standards for occupational noise exposure is set at 85 dB(A) for an 8-hour time-weighted average (TWA). This value is critically important because it serves as a threshold that signifies when employers must take action to mitigate noise exposure among employees. If exposure exceeds this level, employers are required to implement a hearing conservation program, which includes monitoring noise levels, providing hearing protection, and conducting regular audiometric testing. This systematic approach helps prevent auditory damage among workers in environments where noise levels are a safety concern.

Understanding the action level is essential for ensuring compliance with OSHA regulations and promoting workplace safety, especially in industries where loud machinery and equipment are common.
