3M E-A-Rfit Validation Program

Ever wonder how much protection you are getting from your hearing protective devices (HPD) like earplugs or earmuffs? Noise-induced deafness (NID) was the leading Occupational Diseases (OD) in 2014 with 594 cases or 60% of the total OD cases confirmed. 98% of the NID cases were diagnosed at the early stage of the disease. 14 workers suffered from severe hearing loss in the same year. It takes less than 10 seconds per ear and 3 simple steps to combat NID. Use 3M E-A-Rfit validation system. No more guessing game on what you are getting from your HPD.
