What this lesson covers
In this lesson, you'll learn to: apply the 35-foot rule and fire watch triggers, identify prohibited areas and who authorizes the work, set ventilation thresholds and confined space rules, and prepare containers for hot work. Fire prevention is a three-step decision. First, if the object can't readily be moved, move all movable fire hazards to a safe place.
