Hot-work control
What is being checked
The inspector is checking whether the permit, risk assessment, isolations, competence and supervision create an effective control system for hot work, and whether recent work followed that system.

Answer aloud, then open the preparation point.
1What makes this hot work safe to start?
Confirm the approved permit, competent team and physical controls for location approval, gas-free condition, adjacent spaces and pipelines, ignition sources, ventilation, fire watch, fire equipment and post-work monitoring.
2Who can stop or suspend the permit?
Anyone may stop unsafe work. The authorising officer must suspend it if conditions, scope, personnel or simultaneous operations change.
3How are isolations proved?
Identify every energy source, isolate, lock and tag, dissipate stored energy and prove the safe state at the worksite.
4What change requires reassessment?
A change in scope, atmosphere, weather, equipment status, personnel, nearby operations or validity period requires suspension and review.
5Show that the last job was properly restored.
Trace permit closure to removal of tools and personnel, guard replacement, isolation removal, testing and operational handover.
Where an observation may arise
The risk assessment did not address location approval, gas-free condition, adjacent spaces and pipelines, ignition sources, ventilation, fire watch, fire equipment and post-work monitoring.
Physical inspection did not confirm boundaries and opposite sides are inspected, atmosphere is tested and combustibles are removed.
An energy source, stored pressure, gravity, temperature or automatic start was not isolated and proved safe.
The permit was expired, pre-signed, issued away from the worksite or inconsistent with the actual job.
A conflicting operation or permit was not identified and controlled.
The job was closed despite smouldering material, incomplete fire watch, open hot-work leads or unsafe atmosphere.
Past observations for practice
A work plan was not available for specific hotwork carried out in the accommodation area, upper deck.
Master's practical note
Audit one completed permit backwards from equipment restoration to initial isolation. Most weaknesses appear at scope change, shift handover or return to service rather than on the front page.
Equipment boundary and references
Equipment boundary: The permit is an administrative control and does not replace physical isolation, competent supervision or continuous reassessment at the worksite.
