The fire triangle is a model that illustrates the three elements necessary for a fire to occur: fuel, heat, and oxygen.

• The fire triangle consists of three components: fuel, heat, and oxygen.

• Fuel refers to any material that can burn, such as wood, paper, or gasoline.

• Heat is the energy required to raise the temperature of the fuel to its ignition point.

• Oxygen is necessary for the combustion process to occur.

• Removing any ...read more

The cooling method in fire and safety involves the use of water, foam, or gas to reduce the temperature and extinguish the fire.

• Water is commonly used as a cooling method in firefighting, as it absorbs heat and cools down the fire.

• Foam is another effective cooling agent, as it forms a blanket over the fire and prevents oxygen from reaching it.

• In some cases, gases like carbon dioxide or halon are used to displace oxygen...read more
