What this lesson covers
Hot work turns ordinary welding and cutting into an ignition source, so the rules decide where, when and by whom it may be done. This lesson covers the fire-prevention precautions, fire watch triggers, authorization, container and confined space rules, and ventilation thresholds the exam and the job both rely on.
