What is Arc Flash?
- Arc Flash (often called a flashover) is an electrical explosion resulting from a connection through air to ground 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 100kPa, propelling molten metal at 300m/s
- IMPORTANT: Studies show arc flash hazard severity is often higher at low voltage than high voltage systems.

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 electrical network
- Network modelling in specialised software
- Calculations, as incident energy levels (typically expressed in cal/cm² ), and arc flash boundary distances
- Protection coordination analysis
- Equipment labelling 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 - Gide for performing Arc Flash Hazard Calculations (considering system voltage, fault current, protective device clearing time, electrode configuration and 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
