3M™ No-Touch™ Push-to-Fit Earplugs feature a flexible stem to help keep the soft foam tip clean, even when hands are dirty. There is no need to roll the foam before fitting. By eliminating this step, these earplugs help reduce the chance of contaminants being introduced into the earcanal. Our earplugs are packaged 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. 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.
