WHY ELECTRICAL PPE?
Electrical PPE is specially designed to protect against Arc Flash hazards and classified as Arc-Rated (AR). Arc Flash Suits can protect electrical workers from serious injuries caused from electrical and other common hazards at workplaces and replace regular work clothes to mitigate the risk of arc flash burn injuries. A Standard PPE gear or kit usually comprises an Arc Flash Suit, Hood and Face Shield, Gloves, Safety Glasses, Ear Plugs etc.
It is imperative that the first step in protecting your workers from electrical hazards is to evaluate exactly what arc hazards may occur in each unique industrial and utility location. When an arc flash analysis has been performed and markers have been placed on your equipment, these markers will include incident energy levels or arc flash PPE categories on them. The incident energy level should be listed in cal/cm2. This means that the highest energy level that this equipment can produce in an arc flash event will not exceed the posted cal/cm2 rating. 
However, in determining the safety measures and the correct HRC level, a professional evaluation on the risk exposures are both complex and costly. Therefore, the selection of a higher-level PPE to protect the workers is a wise and safer choice.
Your Arc Flash Suit should contain a label that has an Arc Thermal Protective Value (ATPV) rating listed in cal/cm2. The ATPV rating means that the rated PPE will protect the wearer from arc flash energies up to that ATPV value. The Arc Flash PPE is only effective for equipment that has incident energy levels that are lower than the ATPV rating of the PPE. This is a fundamental understanding that all electrical workers should have.
Arc Flash Category
Arc Flash PPE Categories are used in the current NFPA 70E standard to inform workers about the protection they need while working on energized equipment. Each category includes a minimum Arc Rating (AR) value for the required PPE. This value is determined by the PPE manufacturer, and indicates the amount of heat energy (in cal/cm²) that the clothing can absorb or block before the wearer would be likely to receive a second-degree burn.
The ratings are defined by the National Fire Protection Association (NFPA) for arc flash rated clothing of all types. The energy levels measured as calories per centimetre squared (cal/cm2) are defined as:
- Arc-Flash PPE Category 1, Minimum Arc Rating of 4 cal/cm2
- Arc-Flash PPE Category 2, Minimum Arc Rating of 8 cal/cm2
- Arc-Flash PPE Category 3, Minimum Arc Rating of 25 cal/cm2
- Arc-Flash PPE Category 4, Minimum Arc Rating of 40 cal/cm2
