3M Ear Plugs, 200 Pairs/Box, E-A-R Classic 390-1000, Foam, NRR 29, For Industrial Applications

The 3M E-A-R Classic Ear Plugs, the world's first foam ear plug, have revolutionized hearing protection in the workplace over 40 years ago and remain one of the most widely used earplugs globally to this day. Constructed from slow-recovery, low-pressure foam, these ear plugs fit snugly to create a noise barrier that helps protect hearing from loud sounds.

The earplugs are stiff enough when compressed to make fitting easy, yet soft enough to be comfortable in the ear for extended wear. The bright yellow color allows supervisors to conduct quick visual checks to ensure hearing protection compliance. 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 industries such as agriculture, automotive, chemicals, construction, general manufacturing, healthcare, oil and gas, and pharmaceuticals.

With a Noise Reduction Rating (NRR) of 29 dB and CSA Class AL certification, these ear plugs can be fit tested using the 3M E-A-Rfit Validation System. The moisture-resistant design helps maintain a consistent fit, even in humid environments.

Noise exposure is a prevalent issue, with estimates from the National Institutes of Health suggesting 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 through the consistent use of hearing protection.

3M strongly recommends fit testing of hearing protectors, as research suggests that many users may receive less noise reduction than indicated by the NRR due to variations in hearing protector fit, fitting skill, and user motivation. If the NRR is used, 3M recommends that it be reduced by 50% or in accordance with applicable regulations.

The 3M E-A-R Classic Ear Plugs offer outstanding comfort through their unique slow-recovery, low-pressure foam and special cylindrical shape, which help create lower pressure in the ear canal. The proprietary foam is initially firm to make fitting the ear plug easier, then softens once it's in the ear to comfortably conform to the unique shape of each ear canal.

These ear plugs are resistant to moisture absorption, ensuring a consistent fit even in humid environments. They are versatile and can be used for a wide range of industrial and occupational applications, including chipping, chiseling, drilling, furnace operations, grinding, heavy equipment operations, machining, pouring/casting, power fastening, riveting, sanding, sawing and welding.

It is important to note that these 3M industrial and occupational products are intended, labeled, and packaged for sale to trained industrial and occupational customers for workplace use. They are not intended for consumer sale or use and must be selected and used in compliance with applicable health and safety regulations and standards.
