3M E-A-R ARC Earplugs
E-A-R ARC earplugs feature Hear-Through design allowing workers to hear conversations, signals or other critical sounds clearly, while helping protect against impulse noise from an arc flash. They offer double-ended versatility. When the yellow end is inserted, the calibrated noise filter activates immediately to suppress noise to a safer level when arc flash occurs. Insert the red end for protection against continuous hazardous noise. These earplugs also feature a tri-flange, push-to-fit design and are washable and reusable.
