E·A·R™ 340-4004 Ultrafit Christmas Tree Style Corded Earplugs

3M™ E-A-R™ UltraFit™ Corded Earplugs feature a pre-molded Christmas tree design that ensures a comfortable and secure fit in most ear canals. With a no-roll, Christmas tree shape, these earplugs provide quick, clean, and comfortable hearing protection. Simply pinch the stem and insert the earplug into the ear. Even with dirty hands or gloves, the earplug tip remains clean. Made from a soft polymer, these earplugs are washable and reusable, reducing the need for frequent replacement, which minimizes waste and lowers costs. A polyethylene bag keeps the earplugs clean before use. Recommended applications include assembly and machinery, planing, chiseling, cleaning, drilling, kiln operations, grinding, heavy equipment operation, machining, metal repair, painting, pouring/casting, power fastening, riveting, sanding, sawing, and welding. These earplugs are commonly used in industries such as construction, general manufacturing, mining, oil and gas, and transportation. They have a nominal noise reduction rating of NRR=25 dB and SNR=32 dB, and their fit is tested using the 3M™ E-A-Rfit™ Dual Hearing Protection Validation System. Noise is not only present in our daily work and recreational activities, but millions of Americans work in hazardous noise environments every day. According to estimates from the National Institutes of Health, approximately 15% (26 million) of Americans aged 20 to 69 suffer from high-frequency hearing loss due to exposure to noise at work or during leisure activities. Proper use of hearing protectors can prevent noise-induced hearing loss 100%.
