DID YOU KNOW?
The heat from an arc flash can reach up to 35,000°F — hotter than the surface of the sun. [1] That’s why arc flash incidents are among the most dangerous electrical hazards in the workplace.
KNOW THE RISK
- An arc flash occurs when an electric current leaves its intended path and travels through the air to another conductor or ground. [1]
- It can be caused by dust, accidental contact, tool drops, condensation, or equipment failure. [1]
- Arc flash can cause intense heat, pressure waves, flying shrapnel, hearing damage, and severe burns in a fraction of a second. [1]
MITIGATE THE RISK
1. De-energize Before Working
- De-energize all high-voltage circuits before performing maintenance or repairs. Never assume a system is safe unless you’ve confirmed it. [1]
2. Use Guarding and Barricades
- Set up physical barriers and signage to restrict access to arc flash hazard zones. Maintain safe working distances at all times. [1]
3. Use Proper Insulation and Ground Fault Protection
- Wear insulating gloves and tools rated for electrical work. Use GFCIs and ensure proper system grounding to prevent unexpected arcs. [1]
4. Follow Arc Flash PPE Protocols
- Only enter arc flash zones wearing full arc-rated PPE appropriate to the incident energy level. This includes flame-resistant clothing, face shields, balaclavas, and insulated tools.
ARC FLASH SAFETY REMINDER
Arc flashes happen fast — but the consequences can last a lifetime. Only qualified personnel should work near live systems, and only with proper training and PPE. Take the hazard seriously, and you can avoid a catastrophic event.
