The 3M™ E-A-R™ Classic™ Corded Earplugs were the world’s first foam earplugs and are still one of the most widely used earplugs today. Slow recovery, low pressure foam fits snugly to create a noise barrier that helps protect hearing from loud sounds. The earplugs are both flame resistant and moisture resistant. 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.
