When a flashover of electric current leaves its original path and travels in the air from one conductor to another or to ground, Arc Flash happens, which may often turn violent and may also cause injury or death when a human is in close proximity.
The causes of Arc Flash may vary from corrosion, dust, accidental touching, faulty installation, condensation, dropping of tools, material failure, etc., Worker’s proximity to the hazard, Temperature, Time of circuit break are the top important factors that determine the severity of an arc flash injury. An Arc Flash may cause fire (could spread rapidly through buildings), simple burns (Non-FR clothing can burn onto skin), blast pressure (upwards of 2,000 lbs./sq.ft), heat (upward of 35,000 degrees F), sound blast (noise can reach 140 dB – loud as a gun) and dangerous flying objects (often molten metal).
We have developed specific approach boundaries for protecting personnel while also working on or near energized equipment. These boundaries are Flash Protection Boundary (outer boundary), Limited Approach, Restricted Approach and Prohibited Approach (inner boundary).
We offer first-class technical consulting to prevent hazards and recommend various proven protective methods including de-energizing the circuit, work practices, complete insulation, guarding, barricades, ground fault circuit interrupters (GFCI) and grounding (secondary protection).
