The 3M™ E-A-R™ Classic™ Earplugs combine economy with reliable hearing protection. 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. Not only is noise present in our daily routines and recreational activities, but millions of Americans work in hazardous noise on a daily basis. Estimates from the National Institutes of Health suggest that hearing loss afflicts 28 million Americans. About one third of those cases are at least partially attributable to noise. Hearing loss due to noise is almost entirely preventable by judicious use of hearing protection.

• Designed with detectable metal components for food processing and other industries where it is critical to keep earplugs from contaminating products and processes
• Slow recovery, low pressure foam conforms to the unique shape of each ear for enhanced comfort and wearability
• Flame resistant—important for potential arc flash situations and for storage considerations
• Noise reduction rating (NRR) 33 dB. CSA Class AL
• Moisture-resistant—helps maintain a consistent expansion time, even in humid situations
• Not too soft—stiff enough when compressed to make fitting easier yet soft enough to be comfortable in the ear for extended wear
• Poly bag keeps each pair of earplugs available or accessible for re-use.
