3M E-A-R TaperFit 2 large-size uncorded earplugs are designed to fit comforatbly in larger earcanals. Its smooth foam expands in the earcanal to help provide comfortable hearing protection. FROM THE MANUFACTURER The 3M™ E-A-R™ TaperFit™ 2 Earplugs feature a tapered design that easily and comfortably fits into the ear to help reduce your noise exposure. Simply roll the earplug between your fingers, insert it in the earcanal. The low-pressure foam expands for a snug yet gentle fit that helps block high noise levels. Bright yellow color allows supervisors to conduct a quick visual hearing protection compliance check. 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 32 dB, CSA Class AL. However, research suggests that many users will receive less noise reduction than indicated by the NRR due to variation in earplug fit, earplug fitting skill, and motivation of the user. It is recommended that the NRR be reduced by 50% to better estimate typical workplace protection. These earplugs are test compatible with the 3M E-A-Rfit™ Validation System. 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.
