WHAT IS THE FIRE TRIANGLE?
Oxygen, heat, and fuel are frequently referred to as the "fire triangle." Add in the fourth element, the chemical reaction, and you actually have a fire "tetrahedron." The important thing to remember is: take any of these four things away, and you will not have a fire or the fire will be extinguished.
WHAT ARE THE BASIC TYPES OF FIRE EXTINGUISHERS?
There are 5 main fire extinguisher types – Water, Foam, Dry Powder, CO2 and Wet Chemical.
To ensure you’re adequately protected, and you meet current fire safety regulations, you need to have the right types of fire extinguishers for your business premises. You’ll also need the right size and weight of each extinguisher.
HOW TO EXTINGUISH A FIRE?
Removing heat is one of the most effective methods of fire extinction available.
Remember: water is not an appropriate extinguishing material to use on electrical fires, as well as those caused by cooking oils/fats or other flammable liquids.
While cooling removes the heat/ignition element of the ‘fire triangle’, starving the blaze of its fuel source approaches extinction from a different angle.
As the other key component present in the chemical reaction that causes combustion, removing oxygen from the equation is the final way of extinguishing a fire.
Smothering is a technique that is mostly applicable to solid fuel fires, although some materials may contain enough oxygen within their own chemical makeup to keep the blaze burning.
HOW TO OPERATE A FIRE EXTINGUISHER?
Use the four-step PASS technique to properly operate a Fire Extinguisher.
Pull: Pull the pin, this will break the tamper seal.
Aim: Aim low, pointing the nozzle or hose at the base of the fire. Do not touch the horn on a CO2 extinguisher, it gets very cold and can damage the skin.
Squeeze: Squeeze the handle to release the extinguishing agent.
Sweep: Sweep from side to side at the base of the fire, the fuel source, until the fire is out.
