What is Arc Flash ?

Arc flash (often called a flashover) is an electrical

explosion resulting from a connection through air to

round or another voltage phase. Temperatures

reach 20,000°C (four times the sun's surface),

causing:

 

- Severe burns (external and internal from inhaling hot gases)
- Hearing damage from pressure waves
- Eye damage/blindness from UV light

Arc blast with explosive forces exceeding 100 kPa, propelling molten metal at 300 m/s

Important: Studies show arc flash hazard severity 

is often higher at low voltage than high voltage

systems.

Arc flash explained

Electrical Safety UK provides Arc Flash Study

An arc flash study is an analysis of an electrical distribution system to determine by calculation the worst-case arc flash hazard that personnel could be exposed to if an arc flash event occurred.

 

The study involves:

 

- Data collection on the electrical network:

- Network modeling in specialized software

- Calculations, as incident energy levels (typically

expressed in cal/cm²), and arc flash boundary

distances

- Protection coordination analysis

- Equipment labeling with calculated values and

PPE recommendations

- Risk reduction strategies where incident energy

exceeds 8 cal/cm²

- Task-based risk assessments for high-hazard

equipment

- Calculation Standards

 

Arc flash risk is assessed using standards such as:

IEEE 1584 - Guide for Performing Arc Flash Hazard

Calculations (considering system voltage, fault

current, protective device clearing time, electrode

configuration, working distance)

Key Takeaways

✓ Arc flash studies are mandatory for proper risk assessment
✓ De-energization first - always prioritize isolation
✓ Engineering controls are more effective than PPE alone
✓ Training and competency are critical - human error is a major factor
✓ Regular reviews ensure continued safety as systems evolve
✓ Professional assessment identifies cost-effective risk reduction strategies
