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. 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.
