Arc Flash

Today’s focus on safety, for facilities, electrical workers, and final users, requires an understanding of the hazards that may be present in the event of an electrical failure or fault. These hazards can be predicted so that proper equipment and procedures can be used when working with or around electrical distribution. The National Fire Protection Association (NFPA) has set standards (NFPA 70E) for the protection of workers. OSHA regulations require NFPA 70E to be implemented to protect workers working on or around energized electrical equipment.

Arc Flash Hazard WarningTo identify these hazards an Arc Flash study is done. By analyzing the available electrical current during a fault or failure the proper equipment is determined for initial installation and for the protection of staff and workers during maintenance or adjustments. For initial installations, a drawing and detailed list are developed to show available fault currents so adjustment to the installation can be made to reduce fault current and the associated hazard. After the installation is complete, the drawings and list are updated and the final fault availability is defined. These values are then marked onto the equipment where future work may be attempted. The values must meet NFPA 70E requirements for protection of workers attempting to operate on equipment when it is electrically energized.
