Structure fire that has gone out a window or other opening on one floor and ignited materials above, on another floor or other space

Sudden increase in fireline intensity or rate of spread of a fire sufficient to preclude direct control or to upset existing suppression plans

Refers to person or place designated for handling a call for help by alerting the specific resources necessary

Training during which an emergency is simulated and the trainees go through the steps of responding as if it were a real emergency

imminent risk of serious threat to person or property

A fire in which the primary source of heat is electricity, resulting in combustion of adjacent insulation and other materials; may be hazardous to attempt to extinguish using water

A route forming part of the means of escape from any point in a building to a final exit

Calculated time from the ignition until the time at which all occupants of a specified part of a building are able to reach place of safety

Removal of personnel from a dangerous area, burning building, or other emergency. Also refers to act of removing fire-fighters from a structure in danger of collapsing.

Doorway or other suitable opening giving access towards a place of safety

Signs which clearly indicate an exit

Property near fire that may become involved by transfer of heat or burning material from main fire

Warning of a fire originated by a person or by an automatic device

Device which give a signal in response to certain physical and/or chemical changes accompanying a fire

Public or private organization with the aim of safeguarding life and fighting fires

A process of a combustion characterized by emission of heat accompanied by smoke and/or flame

Combination of components giving and audible and/or visible and/or other perceptible alarms of fire. The system may also initiate other ancillary actions.

A building structure arranged outside to assist in safe evacuation of occupants during an emergency

Fire safety; standards for minimizing fire hazards

A qualitative description of the course of a fire with time, identifying key events that characterize the fire and differentiate it from other possible fires. It typically defines the ignition and fire growth process, the fully developed stage and decay stage, together with the building environment and systems that will impact on the course of the fire.

A predetermined place in which persons are in no immediate danger from the effect of fire

Fire protection strategy involving visits to potentially hazardous occupancies for inspection, follow-up analysis and recommendations for actions to be taken in case of specific incidents

Improvements made on properties that enhance the value or fix something outdated or broken

A visible suspension of solid and/or liquid particles in gasses resulting from combustion

A door set to reduce the rate of spread or movement of smoke during the fire

Important procedure in fire fighting in which the hot smoke and gases are removed from inside a structure, either by natural convection or forced, and either through existing openings or new ones provided by fire-fighters at appropriate locations
