The test determines the response of textiles to a standard ignition source and provides data for after-flame time, afterglow time and char length. The NFPA 70E or Standard for Electrical Safety in the Workplace sets requirements for safe work practices protecting personnel by reducing exposure to major electrical hazards. Addressing safety-related work practices, safety-related maintenance requirements and safety requirements for special equipment, the Standard includes guidance for making hazard ID, risk assessments, selecting appropriate PPE, establishing an electrically-safe work condition and employee training.
Be careful not to classify HRC 2 as Class 2. HRC and Level are the correct identifiers but to avoid confusion, use the arc rating. Garments that are HRC 2 compliant are often referred to as daily wear, which includes but not limited to the following: knit or button front FR shirts, work pants or FR jeans and coveralls.

Enespro PPE was founded with the goal of transforming electrical safety PPE by providing USA-made products with multiple improvements that are truly meaningful to workers wearing the gear.

Home Understanding Hazard Risk Categories. Understanding Hazard Risk Categories. Useful Terms and Definitions Electricity The flow of an atoms electrons through a conductor.
Electric Arc The passage of substantial electric current through ionized air. The characteristic of a fabric to resist ignition and to self extinguish if ignited.
Flame retardant A chemical substance used to impart flame resistance — not part of the basic fibers chemistry. Flash-fire A sudden, unexpected and intense fire caused by ignition of flammable solids, liquids, gases or dusts. Flash Hazard A dangerous condition caused by the release of energy from an electric arc. Flash Hazard Analysis A study investigating the potential exposure to arc-flash energy that a worker faces while performing a specific job task. Flash Protection Boundary The distance from an exposed live part within which a person could receive a second-degree burn if an electrical arc were to occur.
HRC Hazard Risk Category The classification of the listed task according to the type of hazard present when performing the task. Thermal Conductivity Rate at which heat will flow through a material. Thermal Protection The resistance to flame and associated thermal transfer through the garment.
TPP Thermal Protective Performance A section of fabric is exposed with a combination of radiant and convective energy. The changes included revised program requirements around an arc flash risk assessment which entails the identification of the hazard in the NFPA 70E Task Table and then estimating the likelihood of injury severity. The condition of the equipment and type of task now determine whether PPE is required or not.
PPE consists of a long list of garments and equipment including arc rated clothing such as pants, shirts, coveralls, jackets, as well as, safety glasses, hard hats, hearing protective devices, gloves and boots.
