A set of measures implemented in buildings and all types of structures to protect them against the effects of fire. Generally, these measures seek to achieve three objectives: save human lives, minimize economic losses caused by fire, and ensure that building activities can be resumed within the shortest possible time.

Among the objectives of the system are the identification of fire hazards, understanding the basic elements of fire chemistry, recognizing fire extinguishing agents and their application according to the type of fuel to be extinguished, among others.

The system is classified into two primary types of protection measures. The first is active protection, which includes actions involving the direct use of installations and equipment for fire protection and firefighting. The second is passive protection, which derives its effectiveness from being permanently present without requiring any direct action on the fire.
