In the event of a fire, when should piped oxygen be turned off?

The location of the Medical Gas shutoff valves should be known in your area. The process should follow something similar to this. However, sites containing medical oxygen should all have a detailed risk assessment and fire safety training for all users as to what to do.

  • Nurse in Charge will assess the situation from the staff
    to decide if the ward is to be evacuated therefore switch
    off, or stay in place and leave on.
  • If turning off – ensure portable cylinders are
    available as required.
  • Remove patients to a place of safety or assembly
    point.
  • If you have evacuated without turning them off, please
    inform Estates who can do this safely. Alternatively, inform
    the Fire Brigade when they arrive.

How do water fire extinguishers work?

Water has a cooling effect on the temperature of the fire, making it impossible for the fire to burn and eventually extinguishing the flames. Water fire extinguishers are equipped with a spray nozzle rather than a jet nozzle, meaning the water is able to quickly cover a much greater surface area, in order to rapidly put out the fire.

What are the fire extinguisher types and uses?

There are 5 main types of fire extinguisher. These are Water, AFF Foam, ABC Powder, CO2 and Wet Chemical. Each have their own strengths and weaknesses.
