Final answer:
Safe arming is required when there are cast members or moving set pieces present in the hazard area immediately before or after the arming. It involves taking precautions to ensure their safety and minimize uncertainty and physical danger.
Step-by-step explanation:
When there are cast members or moving set pieces present in the hazard area immediately before or after the arming, the arming required is called safe arming. Safe arming involves taking precautions to ensure the safety of the cast members and the set pieces while dealing with the potential hazards.
For example, in the case of a fire hazard, safe arming may involve having fire extinguishers readily available, ensuring emergency exits are accessible, and having trained personnel on standby to handle any emergencies.
The goal of safe arming is to minimize the uncertainty and physical danger associated with the presence of hazards alongside the cast members or moving set pieces.
