Arc Flash protective clothing is typically designed for electrical industry, specifically those workers who are involved in tasks that expose them to electrical hazards such as electricians, electrical engineers, linemen, and others who work with or around high-voltage electrical equipment. Our Arc Flash clothing & PPE includes Polo shirts, Sweatshirts, Work Jackets, Coveralls, Anorak Rain & Bomber Jackets and linesman Pyrad Suits made with Gore-Tex Fabric.
An arc flash is a sudden release of electrical energy that occurs when current jumps across a gap between two conductors or from a conductor to a ground. The arc flash generates an intense burst of heat and light that can cause serious injuries, damage to equipment, and fires. This is why it is important to wear the right Arc flash PPE.
Arc flashes can occur in a wide range of electrical systems and equipment, including switchgear, transformers, motors, and other high-voltage components. They can be caused by a variety of factors, including equipment failure, human error, or a short circuit.
Arc Ratings for Arc flash Clothing: What Is the Difference Between ATPV, Ebt and ELIM?
Arc Thermal Performance Value (ATPV) is “the incident energy on a fabric or material that results in sufficient heat transfer through the fabric or material to cause the onset of a second degree burn based on the Stoll curve. The level of protection provided by flame resistant clothing as measured in cal/cm2. An arc rating (ATPV) means that you have a 50% chance of being burned if exposed to an electric arc with the same number of calories of heat. The fabric will usually not break open unless exposed to energy levels higher than the arc rating.
The arc box test method is a standardized test used to evaluate the performance of electrical equipment and materials in the presence of an electrical arc. It is also known as the arc resistance test or the arc tracking test. It is the common test method for ARC flash protection clothing & PPE in Europe.
The test involves placing a sample of the material to be tested inside a box that is filled with a mixture of air and steam. An electrical arc is then generated inside the box, and the sample is observed for signs of damage or degradation caused by the arc.

An arc flash is a sudden release of electrical energy that occurs when current jumps across a gap between two conductors or from a conductor to a ground. The arc flash generates an intense burst of heat and light that can cause serious injuries, damage to equipment, and fires.
Arc flashes can occur in a wide range of electrical systems and equipment, including switchgear, transformers, motors, and other high-voltage components. They can be caused by a variety of factors, including equipment failure, human error, or a short circuit.
The intense heat generated by an arc flash can cause severe burns, as well as ignite clothing and other materials in the surrounding area, leading to secondary fires. The bright light from the arc flash can also cause temporary or permanent vision damage.
To prevent arc flash incidents, it’s important to follow proper electrical safety procedures, including wearing appropriate personal protective equipment (PPE), de-energizing equipment before working on it, and maintaining a safe distance from energized equipment.
Understanding Arc Ratings and Calories
Now that you understand FR clothing is tested and given an arc rating, you know that the arc rating measures the amount of heat the flame resistant fabric blocks when exposed to electric arc. The arc rating is the number of calories that the garment is expected to “absorb” if exposed to an electric arc. Arc rating is, in essence, the level of protection provided to you, the wearer.
Calorie is the unit of measure of the heat energy of an arc flash and the protective level of FR clothing. The bigger the calorie number, the greater the heat energy level of arc flash and the greater the protective level of the clothing. You will be protected from an electric arc if your clothing has a higher calorie arc rating than the calories of heat generated by the arc.
While it does not matter if the fabric has an Ebt, ATPV and or ELIM value, it is important to pay attention to the calorie level the fabric can support* (as expressed in cal/cm2)
