E·A·R™ 340-4002 Ultrafit Christmas Tree Style Corded Earplugs

3M™ E-A-R™ UltraFit™ Corded Earplugs feature a pre-molded Christmas tree-shaped earplug head design, suitable for various ear canal sizes. With a no-roll Christmas tree design, these earplugs provide quick, clean, and comfortable hearing protection. The pre-formed earplug head eliminates the need for rolling, allowing for rapid and proper insertion by employees; even when hands are contaminated with dirt, grease, or other pollutants, the earplug head remains clean. The soft polymer earplugs are washable and reusable, reducing the need for frequent replacement, thereby minimizing waste and lowering costs. 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. These soft polyurethane earplugs have a nominal noise reduction rating (NRR=25dB, SNR=32dB) and can be used with the 3M™ E-A-Rfit™ Dual-Ear Hearing Protection Validation System to verify the fit and actual noise attenuation of hearing protectors. Noise is not only present in our daily work and recreational activities, but millions of Americans are exposed to hazardous noise levels every day. Estimates from the National Institutes of Health indicate that approximately 15% (26 million people) of Americans aged 20 to 69 have high-frequency hearing loss due to exposure to noise at work or during leisure activities. Proper use of hearing protection products can almost entirely prevent noise-induced hearing loss; 3M recommends using the 3M™ E-A-Rfit™ Dual-Ear Hearing Protection Validation System to verify the actual noise reduction achieved by employees when wearing hearing protectors, ensuring adequate hearing protection in noisy environments.
