NFPA 70E for General Industry Mandates that employers conduct a hazard risk assessment to determine the potential arc exposure for employees who work on or near energized parts or equipment. The level of arc exposure is referred to as the Arc Thermal Performance Value (ATPV) and is measured in calories/cm? (often called a cal rating). It also requires employees to wear flame resistant clothing with an ATPV, or cal rating, equal to or greater than the determined arc hazard. Simplify the hazard assessment and compliance process by creating Hazard Risk Categories (HRC) for common tasks an electrical worker would perform. Therefore, an FR clothing item?s HRC rating determines if that item provides sufficient protection for a particular job. As a result, Carhartt FR Clothing carries HRC tags. And, unlike some others, Carhartt HRC tags are externally visible, allowing supervisors and safety officer?s to easily confirm workers are in compliance with NFPA 70E regulations.
NFPA 2112 For Oil & Petrochemical Industries Mandates that employers conduct a flash-fire hazard assessment to determine the risk of a flash fire. It also requires employees to wear flame resistant clothing if the potential for a flash fire exists.
NESC? For Electric Utilities Specifies that employers conduct a hazard risk assessment to determine the potential arc exposure for employees who work on or near energized parts or equipment. Requires employees to wear flame resistant clothing with an ATPV, or cal rating, equal to or greater than the determined arc hazard.
