What does 12 cal cm2 mean?
The ATPV is measured in cal/cm2, and it’s defined as the maximum incident heat energy that a fabric can absorb and lessen the injury to a 2nd degree burn. If the worker is exposed to a potential incident heat energy level of less than 4.0 cal/cm2, the proper ATPV clothing system is 4 cal/cm2.
Are arc flash assessments required?
