Piped oxygen should be turned off in the event of a fire to prevent the oxygen from feeding or intensifying the fire. The specific timing to turn off piped oxygen generally follows these guidelines:
- When there is a confirmed fire in the area where medical gases, including oxygen, are in use, the zone valve controlling oxygen flow to that area should be shut off immediately to reduce fire risk.
- This action is typically performed by an authorized individual such as a charge nurse or unit manager, who must balance patient safety and fire safety.
- When shutting off oxygen, it is critical to provide for patient oxygen needs through alternative means (such as portable oxygen cylinders) and evacuate patients to safety if necessary.
- Turn off the oxygen supply when instructed by fire and rescue services or when a continuous fire alarm is sounding, indicating a serious fire situation.
- Piped oxygen should not be turned off casually or without proper authority because it may compromise patient safety; the decision involves assessment of the fire risk and patient condition.
- After shutting off, only designated facility or fire safety personnel should turn the oxygen supply back on.
In summary, piped oxygen should be turned off immediately if there is an imminent fire hazard in the area using oxygen, or when directed by fire authorities or a continuous fire alarm. The shutoff must be done by trained authorized personnel who ensure patient safety and coordinate evacuation or alternative oxygen provision.
