Arc Flash
Clothing Kits
Complete Protection for Arc Flash Hazards
Arc flash kits contain multiple pieces of arc flash clothing that are used together to protect the wearer from Electric Arc Flash hazards. All our kits come with our heavy duty electrical gear bag.
These specially designed Arc Flash Kits from TaraSafe® will help insulate the wearer from heat, resist breaking open of garment and will not ignite or continue to burn when exposed to a high intensity, short duration explosion and electric arc fire.
We offer Arc Rated suits providing protection from 12 - 45 cal/cm2.
Suggested Norms
EN 61482
Protection against thermal hazards of Electric Arc
Determination of the arc rating(ATPV or EBT50) of flame resistant materials for clothing.
Under this standard the protection property of the fabric or the garment against the thermal effects of an electric arc event is defined as its Arc Thermal Protection Value (ATPV) expressed in cal/cm².
There is no pass / fail criteria under this standard as in case of the Box test. The fabric / garment should have a minimum ATPV rating of 4 cal / cm² according to this standard.
This standard specifies methods to test material and garments intended for use in Heat and Flame resistant clothing for workers exposed to electric arcs.
Protection Class 1 and protection Class 2 are safety requirements covering actual risk potentials due to electric fault arcs.
This standard specifies tests with which it is possible to evaluate materials and protective clothing based on the use of a directed and constrained electric arc under defined laboratory conditions - this is called the Box-test.
For the tests a low voltage procedure is used. The tests can optionally be carried out in two fixed test classes, selected by the amount of prospective short circuit current :
| Class | Arc [kA] | Time [ms] |
|---|---|---|
| 1 | 4 | 500 |
| 2 | 7 | 500 |
The garments must be used to cover the whole body, e.g. jacket and trousers, to attain the correct level of protection.
The clothing falling under the EN 61482-1-2 is further classified as a Category III product.
NFPA 70 E
Electrical Safety - American Standard
The National Fire Protection Association (NFPA) 70E is a comprehensive standard that establishes best electrical safety practices standards on how to protect workers from electric arc flash and arc blast exposure and resulting potential injury and death.
There are 4 Arc Hazard Risk Categories under NFPA 70E defined by the ATPV ratings:
Most people working with electricity only require clothing that meets category 1 (ATPV 4 cal/cm²) or 2 (ATPV 8 cal/cm²) protection characteristics.
NFPA 70E electrical safety standards are aimed more towards those workers who work in category 3 (ATPV 25 cal/cm²) or 4 (ATPV 40 cal/cm²) hazard situations. Their clothing must meet ATPV rating minimums throughout the life of the garment.
| Hazard Risk categories | ATPV (cal/cm²) |
| HRC 1 | ≥4 |
| HRC 2 | ≥8 |
| HRC 3 | ≥25 |
| HRC 4 | ≥40 |
