Fire Extinguisher types.
Know the types of fires, and their appropriate extinguishers.
Each type of fire extinguisher is suitable for different types of burning media and will have a fire rating based on the volume of fire that they are capable of extinguishing. Below is an overview of each type including its suitable uses.
Powder fire extinguishers are ideal for use in mixed risk environments and offer excellent all round fire protection. With a unique class C rating, powder fire extinguishers are the only effective solution for fires involving flammable gases.
Foam fire extinguishers are ideal for use on fire involving solid combustible materials and are highly effective on flammable liquid fires. The layer of foam applied by these extinguishers helps to prevent re-ignition after the fire has been extinguished.
CO2 fire extinguishers are suitable for use on flammable liquid fires and are extremely effective at extinguishing fire involving electrical equipment. CO2 is also one of the cleanest extinguisher agents and leaves no residue behind.
Water fire extinguishers are suitable for use in environments containing solid combustible materials such as wood, paper and textiles. It is important to remember that water conducts electricity and should not be used around electrical equipment (unless water extinguishers with additive are used).
Wet chemical fire extinguishers have a unique class F rating and are usually supplied with a special application lance. The perfect solution for tackling large burning oil fires, wet chemical extinguishers are ideally suited to the kitchen environment.
Water Mist is a new technology that works on the basis of cooling fire, suffocating it and then cooling the burning media to prevent re-ignition using microscopic particles of water. Water mists extinguishers are ideal for covering areas of a building where multiple fire risks can be found.
