ATPV (Arc Thermal Performance Value) rating measures the level of protection against arc flash incidents. Higher ATPV ratings indicate better protection. When selecting FR clothing, consider the ATPV rating to ensure it meets or exceeds the hazards of your work environment. For example, the CC01 Gray Flame Resistant Oil Field Coverall has an ATPV rating of 7.0-9.2 Cal/cm2, suitable for moderate risk environments, while the Flame Resistant Khaki Work Shirts have an ATPV of 8.6, offering substantial protection.
