3M 7000002307 Disposable Foam Earplugs Nrr 33 Db Regular

Product Description

The 3M 7000002307 E-A-Rsoft SuperFit disposable earplugs provide reliable hearing protection through a soft, slow-recovery polyurethane foam construction. Rated at a Noise Reduction Rating (NRR) of 33 dB and classified CSA Class AL, these earplugs are engineered to seal the ear canal securely while maintaining wearer comfort during extended shifts. An orange fitting ring serves as both an insertion depth guide and a quick visual compliance indicator for supervisors and safety personnel. Regular size fits most adult ear canals. Supplied in a poly bag packaging to keep earplugs clean prior to use, these are sold by the box.

These earplugs are suited for industrial and commercial environments where hazardous noise levels are a daily concern. Recommended applications include assembly, machining, grinding, chipping, chiseling, drilling, riveting, sanding, sawing, welding, painting, and heavy equipment operation. They are widely used across agriculture, automotive, chemicals, construction, general manufacturing, healthcare, oil and gas, and pharmaceutical industries. The earplugs are test compatible with the 3M E-A-Rfit Validation System, supporting formal fit-testing programs. A licensed safety officer or industrial hygienist typically oversees earplug program compliance in regulated worksites.

Key Features

• NRR 33 dB rating with CSA Class AL classification for high-noise environments
• Soft, slow-recovery polyurethane foam for comfortable extended wear
• Orange fitting ring guides proper insertion depth and enables visual compliance checks
• Easy roll-down insertion; foam expands to conform to the ear canal shape
• Compatible with the 3M E-A-Rfit Validation System for fit-testing programs

Compatibility

Test compatible with the 3M E-A-Rfit Validation System. Regular size is designed to fit most adult ear canals.

Installation Notes

Roll the earplug down to the smallest diameter possible before insertion, then straighten the ear canal by pulling the outer ear upward and back, and hold the earplug in place for approximately 20 to 30 seconds while the foam expands. Always wash hands before handling earplugs to prevent contamination. Per OSHA 29 CFR 1910.95, a hearing conservation program should include proper fit verification. Note that 3M recommends reducing the stated NRR by 50 percent when estimating real-world noise attenuation during typical use.
