ARC Flash Safety Solutions

An electrical current flowing through ionized air after an initial flashover or short circuit produces an arc. Arcs can generate temperatures of up to 35,000 degrees Fahrenheit. Implementing arc flash safety measures can prevent electrical burns from intense heat while welding.

  1. Training

    • Arc welders must complete a training course on correct welding procedures and safety. Welders must learn to calculate the degree of arc flash hazard and use correct procedures when working with low and high voltages.

    Protection

    • Wear personal protective equipment, or arc flash gear, while welding to protect the body from arc flash. Arc welders should wear eye, hand and head protection, hard-soled insulated shoes or dielectric overshoes and face shields if necessary. Keep protective equipment in usable condition. Do not wear conductive articles, such as jewelry or clothing containing metal fasteners or accents. Use insulated equipment and tools rated for the voltage for which they are being used. Handle conductive materials and tools correctly to avoid accidental contact with live parts.

    Warning

    • Persons not involved in the arc welding procedure must maintain a safe distance by staying at least 10 feet away from the welding procedure. Unqualified persons must enter the welding area accompanied by a qualified person. Post flash hazard labels warning of potential arc flash hazards.
