3MS312-1250 - 3M E-A-Rsoft Yellow Neon Foam Earplugs, NRR 33dB, Box of 200 Pairs

High-Performance Hearing Protection

The 3M E-A-Rsoft Yellow Neon Earplugs (SKU: 312-1250) represent a pinnacle in disposable hearing protection technology. Engineered with a proprietary polyurethane foam formulation, these earplugs offer a Noise Reduction Rating (NRR) of 33 dB, which is among the highest attenuation ratings available for this class of personal protective equipment. This makes them an essential component for safety managers seeking to mitigate noise-induced hearing loss (NIHL) in high-decibel industrial environments.

The key to the E-A-Rsoft's performance lies in its slow-recovery foam. Upon compression (rolling down), the material becomes dense and pliable, allowing for deep insertion into the ear canal. Once positioned, the foam expands gradually, conforming to the unique topography of the wearer's ear canal. This creates an acoustic seal that effectively blocks hazardous noise frequencies while maintaining a low-pressure fit that reduces wearer fatigue over long shifts. The regular size is designed to accommodate a wide demographic of ear canal sizes, ensuring broad compliance across the workforce.

Visually, the earplugs feature a high-visibility neon yellow pigment. This is not merely an aesthetic choice but a functional safety feature, allowing supervisors and safety officers to conduct quick visual compliance checks from a distance. The smooth outer skin of the foam is resistant to soil and oil, helping to maintain hygiene during handling and insertion. These uncorded plugs are dielectric and compatible with other PPE such as welding helmets and faceshields.

Technical Specifications & Compliance

These earplugs are tested compatible with the CSA Class AL standard and ANSI S3.19-1974. The NRR of 33 dB assumes proper fitment; however, real-world attenuation can vary based on insertion technique. The 312-1250 packaging includes 200 pairs per box, with each pair individually poly-bagged to ensure sanitary conditions prior to use. They are latex-free, reducing the risk of allergic reactions among sensitive users.
