3M 7000141055 Over-the-head Earmuffs 24 Db Nrr

Product Description

The 3M 7000141055 is an over-the-head style hearing protection earmuff designed for industrial and trade environments where sustained noise exposure is a hazard. The earcups are molded in bright orange ABS for high-visibility identification on busy job sites. A stainless steel headband resists bending and warping under repeated daily use. Liquid and foam filled cushions seal around the ear to achieve a Noise Reduction Rating of 23 dB, and earcup pivot points tilt to accommodate a range of head sizes. Licensed electricians, HVAC technicians, plumbers, and other trades workers install and use this type of PPE wherever power tools, generators, or mechanical equipment push ambient noise above safe thresholds.

This earmuff suits residential and commercial construction, mechanical rooms, and industrial settings where over-the-head wear style is required or preferred. The bright orange cups make the wearer easily identifiable as wearing hearing protection, supporting site compliance documentation. The lightweight design allows all-day wear without excessive fatigue. No hard hat or face shield adapter is included; this unit is configured for standard over-the-head use only.

Key Features

• 23 dB Noise Reduction Rating (NRR) with CSA Class A certification
• Bright orange ABS earcups for high-visibility identification
• Stainless steel headband construction resists bending and warping
• Earcup pivot points tilt for optimum fit and acoustic seal efficiency
• Liquid and foam filled cushions provide a comfortable, all-day seal
• Lightweight design reduces fatigue during extended wear

Compatibility

Designed as an over-the-head hearing protector for general industrial and trade use where standard earmuff PPE is required by site safety programs or OSHA noise exposure regulations.

Installation Notes

No installation is required; fit by extending the headband until the earcups seat flush and symmetrically over both ears. Per OSHA 29 CFR 1910.95 and equivalent standards, the NRR should be derated when estimating real-world attenuation -- 3M recommends applying a 50 percent derating to the labeled NRR for typical use conditions. Inspect cushions and headband for cracks or compression set before each use, and replace worn cushions promptly to maintain rated attenuation.
