Proper grounding is critical to the safe operation of all stage lighting fixtures.
Periodic inspections must be carried out to insure an adequate ground is maintained on all lighting fixtures. These fixtures may become extremely hot. They must be kept away from people and materials to avoid the risk of injury and fire. Handle them accordingly. Be sure these fixtures are properly secured to their means of support.
