NFPA 70E COMPLIANCE GUIDE The guide shall only be used in conjunction with performing the necessary calculations contained in a flash hazard analysis to determine the proper cal/cM. If the

results of the calculations exceed the cal/cM that correspond to the HRC found on this guide, you must use clothing that complies with the calculation.
