Hearing Conservation Program

UW Safety Office

Every year approximately twenty-two million people are exposed to potentially hazardous noise levels in the United States. OSHA has set both a PEL (Permissible Exposure Limit) and AL (Action Level). The best known is the PEL, which is set at 90 dBA for 8-hours TWA (Time Weighted Average). The AL was established in the early 1980's at 85 dBA for an 8-hours TWA. To prevent negative incidents to University of Wyoming (UW) employers, students, and visitors this program outlines the basic requirements of the OSHA hearing conservation program in the case that the AL is exceeded.
