Fire extinguishers are vital equipment that can extinguish flames and save lives.
Fire alarms are also essential to alert occupants quickly, with experts in installing fire alarms Northamptonshire and elsewhere available.
As well as being different colours, all fire extinguishers have a symbol to indicate what type of fire they are to be used for.
Green A
A letter A inside a green triangle indicates a water or foam fire extinguisher, which can put out fires involving ordinary combustibles. This means solid materials like wood, paper and plastics which are common in homes and offices.
Red B
A B inside a red square indicates a foam or CO? based extinguisher, designed for flammable liquid fires including things like petrol, oil or solvents. They work by smothering the fire.
Blue C
A C in a blue circle indicates a dry powder extinguisher, suitable for flammable gas such as propane. Gas supplies should be safely isolated before extinguishing.
Yellow D
A D in a yellow star is a more specialist type of extinguisher, used for combustible metal fires including magnesium and aluminium powders, which require specialised agents due to extreme heat.
K
Lastly, a black K symbol indicates a wet chemical extinguisher, often seen in commercial kitchens because it can effectively put out cooking oil and fat fires. It cools the fire and forms a soapy layer to stop it from reigniting.
So, whether you’re installing fire alarms in Northamptonshire or Nottinghamshire, consider expert services.
