What does automatic interlock primarily ensure in flame effects safety?

• A. It prevents ignition when safe conditions are not met and shuts down fuel if sensors fail or control signal is invalid.
• B. It speeds up ignition when conditions are unsafe.
• C. It substitutes for testing.
• D. It manages lighting cues.

Answer: (A)

Automatic interlock is a safety feature that prevents ignition unless conditions are verified as safe. In flame effects safety, it continuously monitors sensors and control signals, and if something is unsafe, a sensor fails, or a control signal is invalid, it immediately shuts off fuel to stop a flame from starting or continuing. This behavior is why it’s the correct description: ignition only happens under verified safe conditions, and fuel is cut off when faults are detected. It doesn’t speed up ignition, substitute for testing, or handle lighting cues—those are separate functions outside the interlock’s safety role.
