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.
