Final answer:
In the event of a fire alarm going off, a CPCT should immediately exit the building to ensure safety.
Step-by-step explanation:
In the event of a fire alarm going off in a facility, the first action a Certified Patient Care Technician (CPCT) should take is to immediately exit the building. Safety should be the top priority in such situations, as there is always the uncertainty of whether a serious fire or hazard awaits after an alarm. The potential for extreme physical danger exists, so it is crucial to evacuate as quickly and orderly as possible.
