What must be off before you go to stand by?

• A. The FLIR
• B. The CB
• C. The cage
• D. The chiller

Answer: (A)

The important idea here is that before you move into a standby or entry state, devices that can detect or reveal what’s happening in the area should be disabled to avoid false readings, misinterpretation, and unnecessary exposure or power use. The FLIR is an infrared imaging device; if it’s left on, it can continuously scan heat signatures, which may reveal your presence, confuse readings, or drain power. Turning it off provides a clean, stable baseline and reduces the risk of unintended activity or alarms during standby. The other items are not typically required to be turned off for standby: the circuit breaker is a power-disconnect that belongs to broader safety procedures like lockout/tagout, the cage is a safety barrier that remains in place, and the chiller is equipment that may continue operating for cooling.
