## What the source says

> Occupational noise exposure (hearing conservation) training OSHA required: yes OSHA regulations: 1910.95; 1926.52; 1917.1 Employers in working environments where noise exceeds OSHA’s permissible exposure limit (PEL) of 90 A-weighted decibels (dBA) over an 8-hour workday need to provide training on the impact of noise on the human ear, and how employees can and must protect themselves. If employees are not exposed to noise exceeding 90 dBA over an 8-hour period but are exposed to higher noise levels for a shorter duration, the PEL may still be exceeded. OSHA uses a scale for determining the noise exposure threshold. For example, if an employee is exposed to 110 decibels of noise, they can work safely without hearing protection for only 30 minutes. Training frequency: New hire training Annual retraining Basic respiratory protection training OSHA required:
