An electrical arcing fault is often called an “Arc Flash”. The energy from an arcing fault may be sufficient to cause serious burns to nearby persons or ignite flammable materials such as clothing.
An “Arc Flash” can seriously injure someone who is not wearing the necessary protective clothing.
Australian industrial companies have started to replace the cotton protective clothing is worn by their electrical and utility workers, with arc-rated protective clothing and Personal Protective Equipment.
Untreated cotton is flammable and has no flame retardant properties, which means once it ignites, it will continue to burn. The ongoing burning of cotton clothing against the skin of an individual increase the area, depth and severity of the burn received. By contrast, arc-rated clothing will self-extinguish and stop burning after the arc has been extinguished.

The Australian and New Zealand electrical industry must follow guidelines specified in AS/NZS 4863:2011 ‘Safe working on or near low-voltage electrical installations and equipment’. This includes minimum protective clothing for work where electrical hazards exist. If you are working near low voltage electrical systems, it’s critical for you to select ARC rated clothing, also known as AR clothing.
The standard states that you need ‘Flame-retardant clothing covering the full body (including arms and legs) and not made from conductive material or containing metal threads.’
It’s important to note that AR clothing is flame resistant (FR), but not all FR clothing has been ARC Rated. So, make sure you get the best protection available with ARC rated clothing.
Shirts such as this protect against arc flash and are tested rigorously, and rated in a number of ways.
AR garments are rated with an ARC rating which is expressed ATPV (ARC Thermal Performance Value). There’s also a HRC (Hazard Risk Category) rating number, and ARC rated shirts also need to meet standards relating to high visibility.
