What is Arc Flash PPE (and How Does Clothing Fit In)?
An arc flash is a sudden release of electrical energy through the air, often triggered by a fault or short circuit. The resulting explosion can reach temperatures hotter than the surface of the sun, causing severe burns, injuries, and even fatalities.
Protecting workers from these risks is vital, and that’s why arc flash PPE is essential. Protective clothing plays a key role in keeping people safe.
Understanding arc flash hazards
Arc flash incidents occur in industries such as utilities, energy, rail, and manufacturing, where workers operate or maintain high-voltage equipment. When a fault occurs, an electrical arc releases an intense burst of heat, light, and pressure, potentially causing catastrophic injuries.
The energy level of an arc flash is measured in calories per square centimetre (cal/cm²), and even low-energy events can result in serious harm if adequate protective measures are not in place.
What does arc flash PPE include?
Arc Flash PPE is a complete system designed to shield workers from the thermal and physical impact of arc flash events. A typical arc-rated PPE ensemble may include:
- Flame-resistant coveralls or jackets and trousers
- Protective gloves
- Arc flash face shields or visors
- Safety helmets and balaclavas
- Protective footwear
While each item plays an important part, the clothing layer is often the first and most consistent line of defence.
To mitigate the risk of severe injury, Hazchem Safety’s arc workwear is specifically engineered to provide reliable, certified protection.
Arc ratings and standards: What to look for
Arc-rated clothing is tested to determine how much heat energy it absorbs before the wearer risks second-degree burns. These ratings are displayed as:
- ATPV (Arc Thermal Performance Value) – the energy level the fabric can handle before there’s a risk of burns.
- EBT (Energy Breakopen Threshold) – the point at which the fabric breaks open.
Relevant UK and international standards include IEC 61482-2 and EN ISO 11612, which outline test methods and performance requirements for arc-rated garments.
When specifying or purchasing arc flash PPE, always check for labels that confirm compliance with these standards.
Why protective clothing is central to arc flash safety
Properly designed arc-rated clothing can significantly reduce the severity of burns. Key elements to consider include:
- Coverage: Ensure all areas of the body are protected.
- Fit: Loose-fitting garments offer better insulation, while tight clothes can transmit heat more directly.
- Condition: Damaged or worn garments may not perform as intended.
Clothing should also be flame-resistant and non-melting, as melting fibres can cause further injury. Layering garments can provide additional protection, but all layers must be arc-rated.
