Item Details

  • 3M™ E-A-R™ Classic™ Uncorded Earplugs set the standard in hearing protection as the world's first foam earplugs. Classic™ Small earplugs are slightly smaller in diameter for a comfortable fit in smaller ear canals. The 3M™ E-A-R™ Classic™ Small Earplugs combine economy with reliable hearing protection in a slightly smaller diameter that fits comfortably in smaller ear canals. Slow recovery, low pressure foam fits snugly to create a noise barrier that helps protect hearing from high level sounds. Bright yellow color allows supervisors to conduct a quick visual hearing protection compliance check. Recommended applications include chipping, chiseling, drilling, furnace operations, grinding, heavy equipment operations, machining, pouring/casting, power fastening, riveting, sanding, sawing and welding. These earplugs are commonly used in the following industries: agriculture, automotive, chemicals, construction, general manufacturing, healthcare, oil and gas, and pharmaceuticals. These earplugs have a Noise Reduction Rating (NRR) of 29 dB CSA Class AL. However, research suggests that many users will receive less noise reduction than indicated by the NRR due to variation in earplug fit, earplug fitting skill, and motivation of the user. It is recommended that the NRR be reduced by 50% to better estimate typical workplace protection. These earplugs are test compatible with the 3M™ E-A-Rfit™ Validation System.
