Controlling the Risk
Each hot works task must be planned to reduce the risk of injury/ damage from hot works as far as possible.
Without these controls in place, workers could be severely injured or killed
There are a range of precautions we need to take BEFORE, DURING and AFTER hot work activities.
Before hot work:
• Confirm that the works area does not have an explosive atmosphere by using a gas monitor to check for
flammable gases and oxygen enrichment
• Check all equipment is suitable for use – Gas cylinders checked? tools fit for purpose? Fire retardant PPE worn correctly?
• Ensure workers are trained and competent to complete the task
• Ensure you have the correct fire fighting equipment at hand (check what extinguisher you need!)
• Remove combustible materials from the works area and cannot be ignited by conduction heat
• Barrier off the area if possible to keep unauthorized persons out of the work area
• Hot work permit issued, briefed and understood by workers?
During hot work:
• Maintain good ventilation (natural or forced air)
• Ensure fire fighting equipment is readily available for use
• Use insulating bases where required
• Screen off sources of sparks where possible
• Maintain good housekeeping – remove empty cylinders, bunch hoses together where possible
• Stop if there is ANY issue and report this to the supervisor
After hot work:
• Turn off all equipment
• Mark materials as HOT or barrier off the area
• Monitor the works area to ensure no ignition or re-ignition has taken place
• Sign off the hot works permit as complete to confirm the area has been left safe
