Your Hearing is important, protect it!
Cells and nerves in the inner ear are destroyed by continuous exposure to loud noise. If enough cells and nerves are destroyed, hearing can be permanently damaged.

Steps to prevent hearing damage
1. Wear earplugs when exposed to loud noise & lesser noise for long periods*1
2. Reduce exposure to noise outside of the workplace
3. Use sound-absorbing materials
4. Do not use several noisy machines at once
5. Do not drown out unwanted noise with other sounds
6. If at risk for hearing loss, have your hearing tested once a year
1. Single-Use Earplugs - Self-forming and work as well as most molded earplugs (most common)
2. Molded Earplugs - Must be individually fitted and can be disposable or reusable
3. Earmuffs - Require a perfect seal around the ear
