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 Earplugs 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 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. Not only is noise present in our daily routines and recreational activities, but millions of Americans work in hazardous noise on a daily basis. Estimates from the National Institutes of Health suggest that hearing loss afflicts 28 million Americans. About one third of those cases are at least partially attributable to noise. Hearing loss due to noise is almost entirely preventable by judicious use of hearing protection.
