When should a fire watch be posted during a flame effect sequence?

• A. Only before ignition.
• B. Only during ignition.
• C. Only after ignition and shutdown.
• D. Throughout operation and for a defined post-operation period after ignition.

Answer: (D)

Fire watch must be present throughout the entire flame effect sequence and for a defined period after ignition because hazards can arise at any phase. Before ignition, you need to verify the area is prepared and safe; during ignition, there’s potential for flare-ups, mis-timed ignition, or fuel leaks to cause sudden danger; during operation, ongoing combustion and hot surfaces can produce embers or unexpected flames; after ignition, residual heat or vapors can rekindle even as the sequence winds down. Having a continuous watch ensures rapid detection and response to smoke or fire, protecting people and property and meeting safety protocols. If you only post the fire watch before ignition, you might miss issues that occur during ignition or after; if you post it only during ignition, hazards during the rest of the sequence aren’t covered; if you wait until after ignition and shutdown, dangers during ignition and ongoing operation aren’t addressed.
