FIRE BEHAVIOR & FIRE SAFETY TERMS

Absolute Pressure – pressure based on a zero-reference point, the perfect vacuum.

Acceptable Entry Conditions – conditions that must exist in a space to allow entry and ensure that employees can safely enter into and work within the space.

Acceptable Level of Risk – the minimum risk occurrence magnitude that is accepted by the stakeholders in the community.

Boil-Over – an event in the burning of certain oils in an open-top tank when, after a long period of quiescent burning, there is a sudden increase in fire intensity associated with expulsion of burning oil from the tank.

Combustion – chemical process that involves oxidation sufficient to produce light or heat (fire). Combustible objects are objects capable of being set on fire.

Compliance – adherence or conformance to laws and standards.

Discharge Pressure – water pressure on the fire pump discharge manifold at the point of gauge attachment.

Fire Control – the process of controlling the size of a fire by dumping water on it to decrease the combustion of items caught in the fire.

Foam – an aerated fire-extinguishing solution created by mixing air into foam solution to form bubbles.

Ionization Smoke Detection – the principle of using a small amount of radioactive material to ionize the air between two differentially charged electrodes to sense the presence of smoke particles. Smoke particles entering the ionization volume decrease the conductance of the air by reducing ion mobility. The reduced conductance signal is processed and used to convey an alarm condition when it meets preset criteria.

Kink Test Pressure – a pressure equal to at least 1.5 times the service test pressure.

Line Supervision – automatic monitoring of circuits and other system components for the existence of defects or faults that interfere with receiving or transmitting an alarm.

Non-Fire-Resistive Building – building of a certain type of construction in which the structural members, including walls, partitions, columns, floors, and roofs, do not qualify as fire-resistive.

Photoelectric Light-Scattering Smoke Detection – principle of using a light source and a photosensitive sensor arranged so that the rays from the light source do not normally fall onto the photosensitive sensor. When smoke particles enter the light path, some of the light is scattered by reflection and refraction onto the sensor. The light signal is processed and used to convey an alarm condition when it meets preset criteria.

Occupancy – the purpose for which a building or portion thereof is used or intended to be used.

Water Hammer – a sudden surge of pressure caused when fast moving water is abruptly blocked. This pressure can be as much as seven or more times more powerful than static pressure!

Working Pressure – the maximum allowable pressure to which a sprinkler system, pipe or hose can be subjected to safely.
