The flared bell shape allows for easy fitting and removal. Recommended applications include assembly and mechanical, chipping, chiseling, cleaning, drilling, furnace operations, grinding, heavy equipment operations, machining, metal repair, painting, pouring/casting, power fastening, riveting, sanding, sawing and welding. These earplugs are commonly used in the following industries: agriculture, automotive, construction, general manufacturing, and pharmaceuticals.These soft polyurethane foam earplugs have a Noise Reduction Rating (NRR) of 33 dB and are test compatible with the 3M™ E-A-Rfit™ Validation System. 3M recommends fit testing of hearing protectors. The NRR may overestimate the hearing protection provided during typical use. If the NRR is used to estimate typical workplace protection, 3M recommends that the NRR be reduced by 50% or in accordance with applicable regulations.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.
