Summary
This bulletin examines a tank overflow followed by an explosion and spreading fires, with a responding truck believed to have supplied ignition. It explains how internal combustion engines can ignite flammable atmospheres or accelerate on vapour intake, and highlights vehicle restrictions, conditional hot-work permits and plant-specific air-shut-off requirements.
Classifications: Explosion; explosive atmospheres.
Classifications: Fire; fire safety.
Classifications: Loss of containment; containment loss.
Classifications: Vehicles and driving; driving; road transport.
