- Fire tetrahedron
A model connecting fuel, oxidizer, heat and sustained chemical chain reaction in the explanation of combustion.
- Flash point
The lowest temperature under a specified test at which a liquid produces vapor that can ignite with an external source.
- Autoignition
Ignition without a separate flame or spark under the relevant material and environmental conditions being considered.
- Convection
Heat transfer associated with fluid motion, important when hot smoke and gases move through building spaces.
- Thermal radiation
Transfer of energy by electromagnetic radiation, allowing a fire to heat surfaces without direct flame contact.
- Flashover
A rapid transition toward widespread compartment involvement associated with thermal feedback, whose occurrence depends on the actual conditions.
- Wet-pipe sprinkler
A sprinkler arrangement with water normally present in the distribution piping, distinct from dry-pipe or preaction configurations.
- Preaction arrangement
A system configuration using a defined detection and valve sequence before discharge, whose actual logic depends on the approved design.
- Flow rate
The volume of fluid passing a point per unit time, distinct from pressure or total stored volume.
- Pressure loss
The reduction in fluid pressure associated with specified flow and system conditions, including friction and relevant fittings.
- Trouble signal
An indication of a fault or abnormal system condition that should be distinguished from a fire alarm indication.
- Impairment
A condition in which a protection system or part of it cannot provide its intended function until appropriately restored.

- Oxidizer
A material capable of supporting or intensifying combustion under relevant conditions, requiring compatibility assessment with other stored substances.
- Water-reactive material
A substance that can generate hazardous heat or products on contact with water, requiring material-specific handling and response controls.
- Flammable range
The interval of fuel concentration that can support flame propagation under specified test and environmental conditions.
- Designated-quantity multiple
The dimensionless ratio of a stored material quantity to its applicable designated reference quantity under the stated classification.
