Applications

The 3M™ PELTOR™ CH-3 Headset (MT74H52P3E-111) with Hard Hat Attachment is the specialized “helmet-mount” version of the CH-3 series. It is designed for workers who are required by law or safety protocol to wear a hard hat at all times while communicating via a two-way radio.

Unlike the headband or neckband versions, this model replaces standard arms with P3E attachment slots, allowing the earmuffs to snap directly into most industrial safety helmets.

  • Construction and Infrastructure


    Crane Operations: Riggers and banksmen on the ground wear hard hats for overhead protection. The CH-3 allows them to maintain a constant, wired connection to the crane operator. Demolition: In environments with falling debris, the helmet-integrated communication ensures hearing protection and clear radio contact aren't sacrificed for head safety.

  • Manufacturing and Heavy Industry


    Steel Mills & Foundries: Workers must wear hard hats due to the overhead hazards of cranes and moving ladles. The speech-optimized speakers of the CH-3 help cut through the massive low-frequency rumble of furnaces. Pulp and Paper: The IP68-rated microphone is critical here, as these plants are often humid, dusty, and require regular wash-downs.

  • Oil, Gas, and Petrochemical


    While this specific model is not intrinsically safe (IS), it is widely used in non-hazardous zones of refineries and drilling sites. Facility Maintenance: Technicians climbing ladders or working on multi-level platforms need their hands free and their head protected. The integrated PTT button on the earcup allows them to talk without letting go of a railing to grab a handheld radio.

  • Utilities and Power Generation


    Line Work & Power Plants: For workers in bucket trucks or near high-voltage turbines, the hard hat is non-negotiable. The CH-3 provides Class 5 (29dB–30dB) hearing protection while allowing them to hear their radio clearly over the hum of the grid.
