10. Performance – The Criteria Fire Suppression –
The sharp reduction of the rate of heat release of a fire an the prevention of re growth.
Fire Control –
The limitation of the growth of a fire by pre wetting adjacent combustibles and controlling ceiling gas temperatures to prevent structural damage.
Fire Extinguishment –
The complete suppression of a fire until there are no burning combustibles.
