A fire extinguisher is a portable device that discharges foam to control and get rid of small fires. In order to burn, fires require heat and oxygen. The foam from the fire extinguisher gets rid of the oxygen making the fire unable to spread.

The law then requires a minimum of Two Class A fire extinguishers, located on every storey of your building unless the office space is small, then one is sufficient.
The Fire Classifications
Class A – If the fire includes wood, paper, cloth, plastics etc.
Class B – If the fire contains flammable liquids like gasoline, oil, or kerosene. Class B is a lot stronger.
Class C – Fires including electrical equipment.
Class D – If the fires involve metals like sodium, titanium, magnesium, and lithium. Not controlled, this fire can get out of control fast and risk the lives of others.
Each year in the UK over 22,000 fires happen in the workplace. The most common cause of a fire in a workplace is faulty wires that have been damaged, therefore, fire safety is especially important in the workplace.

- CO2 Fire extinguishers need to be serviced every 12 months and every 10 years.
- Water-based fire extinguishers need to be serviced every 12 months and if the service is extended, then every 5 years.
- Powder-primarily sealed fire extinguishers must be serviced every 12 months like water-based extinguishers but the powdered seal extended service is every 10 years.

How do you stop combustion and extinguish a fire?
The fire triangle is 3 things when put all together can create a fire, when one is removed the fire cannot burn.
Removing Oxygen – Oxygen is one of the three components in a fire triangle. If a fire was to spread using a CO2 extinguisher or fire blanket can get rid of the fire. When the Co2 extinguisher is sprayed, it’ll get rid of the oxygen replacing it with Co2 which is inflammable. Using a Co2 Extinguisher for fires that have been caused by oil fires, electrical fires, or chip-pan fires.
Removing Heat – Removing heat can be done by throwing water onto the hazard but if the fire was from electrical wires, throwing water onto it can cause a serious electrical shock. House fire, paper, or wood friars, can be put out by water.
Removing Fuel – Using fire-resistant materials, fires that have a fuel source will keep burning regardless to get rid of it you’ll have to use fire-resistant materials. Fuel sourced fires are mostly forest fires. When getting removed the process is called Firebreak in which you remove the tress, so it doesn’t spread further.
