3M 312-1201 E-A-R Classic Uncorded Earplugs, Yellow, 200 Pack

The 3M E-A-R Classic Uncorded Earplugs are the world's first foam earplugs and remain 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. These earplugs are both flame-resistant and moisture-resistant, making them suitable for various applications.

The 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 agriculture, automotive, chemicals, construction, general manufacturing, healthcare, oil and gas, and pharmaceutical industries.

These earplugs have a Noise Reduction Rating (NRR) of 29 dB, CSA Class AL. However, research suggests that many users may receive less noise reduction than indicated by the NRR due to variations in earplug fit, earplug fitting skill, and user motivation. 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.

Noise is present in our daily routines and recreational activities, and millions of Americans work in hazardous noise on a daily basis. Estimates from the National Institutes of Health suggest that approximately 15 percent of Americans (26 million people) between the ages of 20 and 69 have high-frequency hearing loss due to exposure to noise at work or during leisure activities. Hearing loss due to noise is almost entirely preventable by the judicious use of hearing protection.

The 3M E-A-R Classic Earplugs set the standard in hearing protection as the world's first foam earplugs. Their slow recovery, low-pressure foam conforms to the shape of the ear canal for enhanced comfort and wearability. The moisture-resistant design helps maintain a consistent expansion time, even in humid environments, and the flame-resistant feature is important for potential arc flash situations and storage considerations.
