Arc Flash Awareness — Toolbox Talk

Arc flash incidents can release temperatures exceeding 20,000°C and blast pressures that throw workers across rooms. This A5 toolbox talk card provides a structured 5-minute safety briefing covering 7 key points: what causes arc flash, the physics of arc blast pressure, PPE requirements by hazard level, approach boundary distances, safe work practices, de-energized work procedures, and emergency response. The front is designed for the supervisor to present to the team — bullet points, clear language, no jargon. The back has discussion questions to engage the crew and an attendance record with signature lines for compliance documentation. Use this for daily pre-start briefings on projects involving switchboard work, high-voltage testing, or any energized electrical work. Cross-reference with our arc flash calculator for incident energy calculations per IEEE 1584.
