Determine the Correct Protection Level, To evaluate Fire Retardant clothing materials in order to measure the heat transferred through the fabric, two values are calculated: Arc Thermal Performance Value (ATPV)...the minimum energy causing the predicted onset of second-degree burns and Heat Attenuation Factor (HAF)...the percentage of total energy of the arc that the fabric prevents from passing through, OSHA requires that each employer must assess the potential hazards in the work environment and determine the appropriate clothing materials using ASTM PS57-97. Always do a hazard assessment. You will need to know electrical system voltage, fault current available, number of phases, Arc time duration, estimated Arc gap, minimum distance from the Arc, and Arc configuration.
