Overview
The Honeywell FH31RB Pro-Hood arc flash protection hood is engineered for workers in electrical and hazardous environments requiring 31 cal/cm² ATPV (Arc Thermal Performance Value) protection. Manufactured by Honeywell Salisbury, this hood combines a full-coverage design with an arc-rated replaceable lens to shield the face and neck from arc flash incidents. Meeting current NFPA 70E and ASTM F2178 standards, the FH31RB delivers critical personal protective equipment for compliance in high-risk electrical work environments.
