Uncorded ear plugs are made of moisture-resistant, nonflammable, dermatologically safe foam. Foam is nonirritating. Foam's slow recovery provides comfort with low pressure. NRR 29 ear plugs fit a wide range of ear canals and are tested to ANSI S3.19-1974.
These classic earplugs were the world's first foam earplugs and are still one of the most widely used earplugs today. They are stiff enough when compressed to make fitting easy, yet soft enough to be comfortable in the ear for extended wear. Slow recovery, low pressure foam fits snugly to create a noise barrier that helps protect hearing from loud 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.
