More than 40 years ago this simple hearing protector, the world’s first foam ear plug, revolutionized hearing protection in the workplace and has remained to this day one of the most widely used earplugs in the world. The 3M E-A-R Classic Ear Plugs OCS1137 are constructed from slow-recovery, low-pressure foam. They fit snugly to create a noise barrier that helps protect hearing from loud sounds. These ear plugs are stiff enough when compressed to make fitting easy, yet soft enough to be comfortable in the ear for extended wear. Bright yellow color allows supervisors to conduct quick visual hearing protection compliance checks. 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 ear plugs have a Noise Reduction Rating (NRR) of 29 dB, CSA Class AL. These earplugs can be fit tested with the 3M E-A-Rfit Validation System. Moisture resistance helps maintain a consistent fit, even when humidity is present. Not only is noise present in our daily routines, but millions of Americans work in hazardous noise on a daily basis. Estimates from the National Institutes of Health suggest that approximately 15 percent of Americans (26 million people) between the ages of 20 and 69 have high frequency hearing loss due to exposure to noise at work or during leisure activities. Hearing loss due to noise is almost entirely preventable by consistent use of hearing protection. Note: 3M strongly recommends fit testing of hearing protectors. Research suggests that many users will receive less noise reduction than indicated by the NRR due to variation in hearing protector fit, fitting skill, and motivation of the user. If the NRR is used, 3M recommends that it be reduced by 50% or in accordance with applicable regulations.

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.
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.
Doing it right means doing it safely. That means choosing the right safety products before the project begins.

We strive to give consumers the confidence in knowing they are prepared with reliable products from a trusted brand, so they can stay focused on the task at hand, not on their safety products.
Roll ear plug slowly with thumb and fingers. Gradually increase pressure to compress plug to a very thin, crease-free cylinder.
Reach around your head with opposite hand to pull ear outward and upward, then insert compressed ear plug well into ear canal.
Check fit after ear plug expands in ear. Touch ear plug. You should feel only the end of ear plug. Listen to steady loud noise with ear plugs in both ears. Cover ears with tightly cupped hands. Noise should sound about the same whether or not ears are covered.
If you feel most of ear plug outside the ear canal, remove ear plug and repeat fitting. If you cannot obtain a good fit, try a different size or type of hearing protector.
