3M™ E-A-R™ UltraFit™ Earplugs 340-4007, Metal Detectable, Corded, Poly Bag, 400 Pair/Case

The 3M™ E A R™ UltraFit™ Metal Detectable Corded Earplugs feature a metal detectable ball bearing for high detectability and a “no roll”, triple flange design that provides quick, clean, and comfortable hearing protection. Simply hold the stem and push the earplug into the ear. The tip stays clean even if hands are dirty or gloves are worn. The soft polymer earplugs are washable and reusable so they don’t need to be replaced as often, reducing waste and lowering costs. Poly bag keeps earplugs 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: construction, general manufacturing, mining, oil and gas, and transportation. These soft polymer earplugs have a Noise Reduction Rating (NRR) of 25 dB and 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 approximately 15 percent of Americans (26 million people) between the ages of 20 and 69 have high frequency hearing loss due to exposure to noise at work or during leisure activities. Hearing loss due to noise is almost entirely preventable by judicious use of hearing protection.*The NRR may overestimate the hearing protection provided during typical use. 3M recommends reducing the NRR by 50% for estimating the amount of noise reduction provided.
