Hot work is any operation or task that produces heat that could injure a worker or that could act as a source of ignition, causing a fire or explosion.

Workers involved in hot work such as welding, cutting, soldering, and grinding are at risk of fires and leaks of flammable gas. Potential hazards include burns, grind-related injuries, and injuries from sparks.

A hot work program should contain:

• Documented identification of all tasks involving hot work
• Hazard identification/risk assessment
• Adequate safe work procedures for hot work
• Training and supervision of all workers and contractors who perform hot work
