What does 'line of fire' refer to in backstage safety?

• A. The area where a moving piece could strike personnel; must be cleared before operation.
• B. The path where lighting cables are routed.
• C. The boundary for permitted noise levels.
• D. The area where loudspeakers are tested.

Answer: (A)

The line of fire is the area where a moving piece of equipment could strike someone. In backstage safety, it’s the path a moving element—like scenery flown in the rig, a lift, or a swinging prop—could reach during operation. Because someone in that zone could be hit or crushed, that area must be cleared and secured before motion begins, and operations should stop if anyone enters it. This concept is about the risk zone around moving gear, not about cable routing, noise limits, or loudspeaker testing.
