What is Arc Flash?
An arc flash is an intense burst of light and heat from an electrical explosion caused by a fault or short circuit through the air to another conductor or ground. This can result in an arc blast — a violent pressure wave that vaporises materials, hurls debris, and can cause serious injury or death.
The HSWA mandates that PCBUs must eliminate or minimise these risks. That starts with knowledge.
Key takeaways from real events:
-
Arc flashes can produce incident energy levels beyond PPE limits
-
Arc flash boundaries can extend 7 metres or more
-
Failure to manage these risks can result in $150K+ in penalties and serious harm
At Athenry, we’re embedding this awareness into every part of our operation:
-
Revising Safe Work Method Statements
-
Ensuring staff carry arc-rated PPE as standard
-
Advising clients on arc flash risk assessments and MCC upgrades
-
Insisting: no live work under pressure — ever
This isn’t just about compliance — it’s about care. For your team, your equipment, and your future.
