To extinguish a class A fire which is the most appropriate extinguisher? Water CO2 Foam Foam trolley - Water Fuel can be in three physical states; solid, liquid and... Conduction Class A Steam Gaseous - Gaseous Fire spread of heat through thermal energy using water and air currents is? Conduction Convection Radiation Combustion - Convection The fire triangle is made up of three elements:

The three most important chemical elements particular to firefighting are - Carbon, Hydrogen, Oxygen Common materials that burn all contain the chemical element of - Carbon (Paper, wood, cloth, plastic, flammable liquids) When oxygen combines with a combustible material (fuel) and heat is introduced, the combination creates - Combustion Combustible materials contain energy of - Potential Heat energy always moves from - Warm to cool/Hot to cold Heat energy is measured in - BTU's The rea...
