Do arc flash suits work?
The energy released in an arc flash can easily cause regular, work clothing to catch on fire, which can dramatically increase the extent and severity of the of burn injury. Electrical PPE replaces regular work clothes to mitigate the risk of arc flash burn injuries.
How do I choose an arc flash suit?
The incident energy level should be listed in cal/cm2. This means that the highest energy level that this equipment will produce in an arc flash event will not exceed the posted cal/cm2 rating. Your arc flash PPE should contain a tag that has an arc thermal protective value (ATPV) rating (also listed in cal/cm2).
How long are arc flash suits good for?
Most electrical safety experts and safety professionals agree that it’s practical to set up a plan to replace arc flash suits/ kits every 5 years or sooner.
Is standard for arc flash suit?
IEC 61482-2 is the overall standard covering protective clothing against thermal arc hazards of an electric arc. This standard also covers various aspects of the garment design. Garments complying with all of these requirements should be marked with the IEC 61482-2 symbol as well as the level of protection it meets.
What is Cal cm2 mean?
Calories per Centimeter Squared
Calories per Centimeter Squared (cal/cm2): This is a number identifying the amount of energy that can be delivered to a point at a particular distance from an arc flash. Once this value is known, the ATPV rating of the flash clothing required for work at that distance from the potential flash hazard is also known.
How often does arc flash gear need to be tested?
Keep Purchase Dates and Time in Service Documented: While you don’t need to ship your arc flash kits out for testing every six months as you do with electrical gloves, knowing when you last purchased your PPE can help warn you when you need new gear.

How many times can you wash arc flash clothing?
The general rule of thumb is to own 5 sets of arc flash clothing, with each set being washed and worn once per work week.
At what voltage is arc flash a concern?
Most 400 V and above electrical services have sufficient capacity to cause an arc flash hazard. Medium-voltage equipment (above 600 V) is higher potential and therefore a higher risk for an arc flash hazard.
What is an arc flash suit and how does it work?
Arc flash suits are designed to protect the electrical technician from heat and to reduce or minimize total burn injury. This helps to provide the user with extra seconds of protection to help escape possible secondary explosions or fires in the work area. Arc Flash suits can increase the chances of survival.
What are the different types of arc flash?
The Arc flash categories range from as 12 CAL to 140 CAL, and a wide variety of clothing ranges such as Arc Flash undergarments, Arc flash casual wear. How does an Arc occur? Arc flash suits are designed to provide protection from arc flash heat exposures.
