Ear Protection
Ear Protective Devices
OSHA requires employers to provide suitable hearing protection devices for workers exposed to high noise levels in the workplace.
How to Use Foam Earplugs
The appropriate hearing protection device depends on the specific noise levels and hazards present in the workplace.Here is a brief description of common OSHA-required ear protective devices:
- Earplugs: Earplugs are small, often disposable, devices that are inserted into the ear canal to block noise. They come in various materials, such as foam, silicone, or wax, and can be pre-molded or custom-molded to fit the individual's ear. Some earplugs are also reusable and can be cleaned. The use of ear plugs should be carefully reviewed by a health and safety professional because chemical contaminants could be introduced into the ear.
- Earmuffs: Earmuffs are larger devices that cover the entire outer ear, creating a seal to block out noise. They consist of cushioned cups connected by a headband, which can be adjustable for a comfortable fit. Some earmuffs are designed with specific noise reduction features, such as electronic noise-canceling technology or passive noise reduction.
- Headphones: Radio headset with throat microphone. Provide hearing protection and communications. Desirable in emergency conditions.
- Canal caps: Canal caps are similar to earplugs but are connected by a flexible band or headband. They are designed to seal the entrance of the ear canal without being inserted deeply. Canal caps can be a convenient alternative when workers need to frequently put on and remove hearing protection.
- Semi-insert earplugs: These devices consist of soft earplugs connected by a lightweight headband. They are inserted partially into the ear canal, providing moderate noise reduction.
