Chain of Command
Illness, Sharp or Severe, having a rapid onset and short duration.
Acute
Equipment designed and approved for use in flammable atmospheres that is incapable of releasing sufficient electrical energy to cause the ignition of a flammable atmosphere mixture.
Intrinsically Safe Equipment
Wood with high moisture content.
Green Wood
A chemical process of oxidation that occurs at a rate fast enough to produce heat and usually light in the form of either a glow or flame.
Combustion
Guide to decision making in an organization.
Policy
To make less harsh or intense; to alleviate.
Mitigate
The person who initiates the message using both verbal and nonverbal communication.
Sender
Expansion of excess moisture within masonry materials due to the heat of a fire, resulting in tensile forces within the material, causing it to break apart.
Spalling
A form of energy characterized by vibration of molecules and capable of initiating and supporting chemical changes and changes of state.
Heat
Step-by-Step written plan that is closely related to a policy.
Procedure
Any agent, condition, or experience that causes stress.
Stressor

Pyrolysis
A set of principles, protocols, or procedures that explain how to do something.
Standard
Allowing firefighters to rest, re-hydrate, and recover during an incident.
Rehabilitation
Roll call of all units (crews, teams, groups, companies, sectors) assigned to an incident.
Personnel Accountability Report (PAR)
Construction that does NOT meet the requirements for noncombustible construction.
Combustible construction
The kinetic energy associated with the random motions of the motions of the molecules of a material or object; often used interchangeably with the terms heat and energy. Measured in Joules or BTUs.
Thermal Energy
A collection of rules and regulations that has been enacted by law in a particular jurisdiction.
Code
Perception of the surrounding environment, and the ability to anticipate future events.
