The 3M E A R E A Rsoft SuperFit Earplugs, Hearing Conservation, seal the earcanal with soft, slow recovery foam for excellent noise reduction and reliable hearing protection. An orange fitting ring provides a guideline for proper fitting and visual compliance check. The earplugs are easy to roll down and insert, then expand within the earcanal for a comfortable, secure fit. These regular size earplugs fit most earcanals. Earplugs come in a poly bag to keep them clean prior to use. 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, chemicals, construction, general manufacturing, healthcare, oil and gas, and pharmaceuticals.
These earplugs have a Noise Reduction Rating (NRR) of 33 dB, CSA Class AL. Earplugs are made of a polyurethane. Test compatible with 3M E A Rfit Validation System. The NRR may overestimate the hearing protection provided during typical use. 3M recommended reducing the NRR by 50% for estimating the amount of noise reduction provided.
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.
