To jettison a load of water or retardant from an aircraft, or terminate a preplanned aircraft maneuver.

A designated area where unused quantities of water or fire retardant may be jettisoned, usually to permit an airtanker to land with less than a full load.

Term frequently used in aviation operations, usually in connection with a stated altitude.

Grinding or wearing away of a surface by rough materials.

A localized collection of pus surrounded by inflamed tissue.

According to the American Meteorological Society, (also called vapor density). In a system of moist air, the ratio of the mass of water vapor present to the volume occupied by the mixture; that is, the density of the water vapor component.

Act of soaking up and retaining a gas in liquid or in a solid; also retention of radiant energy.

Material (usually a flammable liquid) used to initiate or increase the spread of a fire.

The potential fire loss a community is willing to accept rather than provide resources to reduce such losses.

The burning of understory prior to the sale of forest products to improve the efficiency of timber marking and harvesting.

An event, usually managed by organizations external to the fire community, for which the primary focus is for dealing with an accident and assistance to potential victims. This category includes accidents such as: automobile, aircraft, train, watercraft, and industrial.

Agency-specific accounting data. Each agency assigns a specific accounting code to an incident.

Cost reports utilized for financial obligation purposes.

Description of the methods used to determine the certainty and precision of the fire location at the point of origin.

Any tactical plan developed by any element of ICS in support of the incident action plan.

A fire in which a solid flame develops in the crowns of trees, but the surface and crown phases advance as a linked unit dependent on each other.

Any fire that has not been called "out".

Resources checked in and assigned work tasks on an incident.

The thing that a person is doing when a wildland fire ignition occurs.

A device for connecting hoses of the same size with non-matching hose threads, or connecting a threaded coupling to a quick-connect coupling.

Bonding or adherence between rubber lining and the jacket.

According to the American Meteorological Society, a process in which a system does not interact with its surroundings by virtue of a temperature difference between them. In an adiabatic process any change in internal energy (for a system of fixed mass) is solely a consequence of working. For an ideal gas and for most atmospheric systems, compression results in warming, expansion results in cooling.

A public information description of the relative severity of the current fire danger situation.

A team that supports incident agencies by processing payments for resources. Resources may include emergency equipment, casuals, local vendors for supplies, etc.

Individual responsible for incident agency business management functions, such as personnel, procurement, fiscal, etc.

Moving a hose lay toward a specified area from the point where the hose-carrying apparatus has stopped.

That portion of the fire with rapid fire spread with higher intensity which is normally burning with the wind and/or up slope.
