Firefighting Agents and Extinguishers

Waten The standard method is to pour water onto the fire. This reduces the heat, hopefully to the point that the fire can no longer burn. However, water is not suitable for liquid fuel fires, because it is likely to spread the fuel and make the fire larger, nor for electrical fires because of the risk of electric shock. 

Foam Foam is put onto fires fuelled by liquid fuel. It works by preventing oxygen getting to the fire but does not spread the fuel around. 

Powder Powder is used on electrical fires, as it does not conduct electricity. Like foam, it works by cutting off the oxygen supply to the fire. 

Fire beaters and rakes Fire beaters and rakes are low-tech ways to fight small fire in scrab. They work by spreading the fire out, thus reducing the concentration of heat, and by removing the source of fuel from the fire. 

Extinguishers Fire extinguishers are canisters of water, foam, or powder that can be carried by one person to the fire. They are of limited capacity but can be used to stop a fire before it becomes large.
