3M 7000029951 Disposable Foam Earplugs Nrr 33 Db Uncorded

Product Description

The 3M 7000029951 is a disposable, uncorded foam earplug designed for reliable hearing protection in high-noise work environments. Built with a bell-shaped body and super-soft, slow-recovery foam, the earplug conforms to the ear canal for a consistent acoustic seal. It carries a Noise Reduction Rating (NRR) of 33 dB and meets CSA Class AL certification. The flanged end simplifies insertion and removal, making it practical for repeated use throughout a shift. Hearing conservation programs in industrial, construction, and mechanical trades rely on this style of earplug as a cost-effective, single-use solution.

These earplugs are suited for industrial and commercial settings where elevated noise levels require OSHA-compliant hearing protection. Each pair ships in an individual poly bag that keeps the earplugs clean before use and supports hygienic re-use when conditions allow. The regular size fits most users. They are also test-compatible with the 3M E-A-Rfit Validation System, making them a practical choice for facilities that conduct fit testing as part of a formal hearing conservation program.

Compatibility

Compatible with the 3M E-A-Rfit Validation System for quantitative fit testing. Designed as a standard uncorded disposable earplug suitable for general-industry hearing protection programs.

Installation Notes

Earplugs should be fitted by rolling the foam into a tight cylinder before insertion, then holding in place until the foam fully expands to seal the ear canal. Safety officers and industrial hygienists typically oversee earplug fit and use within formal hearing conservation programs. Refer to OSHA 29 CFR 1910.95 and applicable site safety policies for hearing protection requirements. Discard any earplug that is soiled, torn, or has lost its ability to expand.
