In One of the major hazards associated with firefighting operations is the toxic environment created by combusting materials. The four major hazards associated with these situations are Smoke' Oxygen deficient atmosphere Elevated temperatures Toxic atmospheres To combat these potential effects, firefighters carry self-contained breathing apparatus

Additional risks of fire include fall,  structural collapse.

The first step of a firefighting operation is a reconnaissance to search for the origin of the fire and identification of the specific risks and any possible casualties.

A fire can be extinguished by water. fuel removal.chemical flame inhibition.

One of the main risks of a fire is the smoke: it carries heat and poisonous gases, and obscures vision. Paul Grimwood introduced the concept of tactical ventilation in the 1980s to encourage a better thought-out approach to this aspect of firefighting.

In the US, fires are sometimes categorised as "one alarm", "all hands", "two alarm", "three alarm" (or higher) fires. There is no standard definition for what this means quantifiably, though it always refers to the level response by the local authorities. In some cities, the numeric rating refers to the number of fire stations that have been summoned to the fire. In others, the number counts the number of "dispatches" for additional personnel and equipment.
