3M E-A-Rsoft SuperFit Earplugs 311-4109 - Metal Detectable - 2000 Pair/Case
The 3M E-A-Rsoft SuperFit Metal Detectable earplug with metal detectable cord.
3M E-A-Rsoft SuperFit Metal Detectable Corded Ear Plugs feature a small stainless steel bead inside the ear plug and metallic powder in the cord to make them metal detectable. Metal detectable foam ear plugs were developed for food processing and other industries where it is critical to keep ear plugs from contaminating products and processes. These ear plugs seal the ear canal with soft, slow-recovery foam for noise reduction and reliable hearing protection. The tapered ear plugs are easy to roll down and insert, then expand within the ear canal for a comfortable, secure fit. 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 ear plugs are commonly used in the following industries: agriculture, automotive, chemicals, construction, general manufacturing, healthcare, oil and gas, and pharmaceuticals. These ear plugs have a Noise Reduction Rating (NRR) of 32 dB. Ear plugs are made of a polyurethane. Test compatible with 3M E-A-Rfit Validation System. *Note: 3M strongly recommends fit testing of hearing protectors. Research suggests that many users will receive less noise reduction than indicated by the NRR due to variation in hearing protector fit, fitting skill, and motivation of the user. If the NRR is used, 3M recommends that it be reduced by 50% or in accordance with applicable regulations.
