If piped in oxygen (O2) is contributing to a fire, what should you do?

Shutting off the oxygen at the source, if possible, is a critical action during a fire where piped in oxygen is involved. Oxygen is a key element that fuels combustion, and if the supply of oxygen can be cut off, it will help to mitigate the severity of the fire and reduce its ability to sustain itself. This action should be taken carefully and only if it can be done safely, as the urgency to act quickly can often lead to hasty decisions.

Other options do not address the primary issue of controlling the fuel for the fire. Evacuating the building is important for safety, but if the oxygen supply continues to feed the flames, the risk remains. Using water may not be effective or safe, especially in the presence of certain fire types, such as those involving electrical equipment or flammable gases. Waiting for the fire department might lead to unnecessary damage or injury if immediate action can be taken to stop the oxygen supply. Ultimately, managing the oxygen source is a key step in fire control strategies, particularly in environments where oxygen is piped in.
