3M OCS1137 Classic Earplugs in Pillow Pak (Case of 200)

Ideal for use where noise is a problem, either in work or leisure activities (view larger).

The 3M E-A-R Classic Earplugs were the world's first foam earplugs and are still one of the most widely used earplugs today. These earplugs are stiff enough when compressed to make fitting easy, yet soft enough to be comfortable in the ear for extended wear. Slow recovery, low pressure foam fits snugly to create a noise barrier that helps protect hearing from loud sounds. Bright yellow color allows supervisors to conduct quick visual hearing protection compliance checks.

Comfortable fit for all day wear (view larger).

Recommended applications include chipping, chiseling, drilling, furnace operations, grinding, heavy equipment operations, machining, pouring/casting, power fastening, riveting, sanding, sawing and welding. These earplugs are commonly used in the following industries: agriculture, automotive, chemicals, construction, general manufacturing, healthcare, oil and gas, and pharmaceuticals. These regular size earplugs comfortably fit most people.

These earplugs have a Noise Reduction Rating (NRR) of 29 dB, CSA Class AL. These earplugs are test compatible with the 3M E-A-Rfit Validation System. Moisture resistance helps maintain a consistent expansion time, even when humidity is present. Flame resistance helps protect against potential arc flash situations and provides for safer storage.

Why Use Hearing Protection?

Hearing loss due to noise is almost entirely preventable by judicious use of hearing protection. To find out which hearing protection products are best for you, try different devices from the wide variety available today. Be sure to carefully read the instructions — hearing protection must fit properly and be worn correctly to do the job.

Hearing protector effectiveness is specified by a Noise Reduction Rating (NRR), typically ranging from 15 to 35 decibels. In practice, the protection that normally can be achieved is about 10 to 20 decibels. The more carefully you fit and wear hearing protectors, the higher your protection will be.
