3010 – 09 – When to Wear Hearing Protection

Noise is also a serious safety hazard. Since it is invisible, it makes it much more difficult to know how bad the hazard is in the shop. They should involve a professional to do a noise level study. Acceptable exposure time is dependent on the level of noise present in the shop. The louder the noise in the work area, the less exposure to the worker and more measures are needed to keep them safe.
When too much noise is present, there are three types of PPE used for hearing protection:
• Pre-formed earplugs or molded earplugs are fitted devices made of silicone rubber and can be disposable or reusable.
• Single-use earplugs are self-forming plugs that are disposable. When used correctly, they are as effective as pre-formed earplugs.
• Earmuffs are full-ear coverings that are made for a perfect seal around the ear.
If employees are exposed to noise that hits at least 85 decibels over an eight-hour period, the employer has to institute a hearing conservation program with regular hearing tests by a professional.
