How to use Water Fire Extinguishers
I’m often asked, when completing fire extinguisher maintenance or fire risk assessments, which extinguishers are for use on which fires and how to use them.
So, in the first of a short series of Blogs, I shall be explaining the basic method of operation and type of use for fire safe use of fire extinguishers.
Let’s start by looking at Water Extinguishers.
These are for use on “Carbonaceous” Class A Fires, involving Wood, Paper or Textiles.
As these extinguishers contain water, they are not suitable for use on live electrical equipment or flammable liquid fires.
Water Extinguishers are either coloured Red or finished in Stainless Steel, but will always feature a RED label indicating the extinguisher contents.
Water extinguishers come in three, six or nine litre sizes, ranging in weight from 5 to 16 kilograms, but can be used from a floor standing position if required.
To use the extinguisher, firstly remove it from it’s Wall Bracket or Stand by simply lifting away and placing on the floor.
Next locate and remove the safety pin, by either twisting and pulling out or simply pulling out of the extinguisher handle. (Pull)
Then locate and remove the nozzle from it’s retainer on the base or side of the extinguisher and point the nozzle at the base of the fire. (Aim)
Now squeeze the extinguisher handles together to operate the extinguisher, not forgetting to aim the nozzle directly at the base of the fire. (Squeeze)
Move the nozzle in a sweeping motion at the base of the fire. (Sweep)
You may find it helpful to remember the word PASS

Remember you can control discharge of the extinguisher by simply squeezing or releasing the handles.
Vertical spreading fires must always be attacked at the lowest point and then followed upwards.
After the fire is extinguished, identify any hot spots to prevent re-ignition.
And don’t forget to contact a qualified maintenance supplier like http://www.renovatio.uk.com, to refill and recharge your extinguisher, even after partial use!
