That phase of a fire where the fuel is ignited and consumed by flaming combustion.

A legal limit on the level of atmospheric contamination. The level is established as the concentration limits needed to protect all of the public against adverse effects on public health and welfare, with an adequate safety margin. Primary standards are those related to health effects. Secondary standards are designed to protect the public welfare from effects such as visibility reduction, soiling, material damage and nuisances. 

Emergency care or treatment given to an ill or injured person before regular medical care can be obtained. First aid is generally provided by someone other than a physician. On incidents, most first aid is provided in the field or camp by medical unit personnel such as Emergency Medical Technicians (EMT).

Measurement of pressure (e.g., pump pressure, nozzle pressure, friction loss in hose, pressure loss or gain due to elevation).

Fuel breaks built in timbered areas where the trees on the break are thinned and pruned to reduce the fire potential yet retain enough crown canopy to make a less favorable microclimate for surface fires.

In fire service, the number of feet (meters) of vertical lift from the surface of the water to the center of the pump impeller. In testing, e.g., fire department pumpers are required to discharge their rated capacity at 150 pounds (1034 kPa) net pump pressure at a 10-foot (3 meter) lift. The suction gauge would indicate the vertical suction lift in inches of mercury when the pump was primed with no appreciable water flowing. 

Permanent facility at which aircraft are stationed for use in air attack operations.

An airfield where airtankers are reloaded but not permanently stationed.

Flashlight, ordinarily worn by firefighter on the front of the helmet.

Card or documentation required to be on board the aircraft which approves use and indicates specific types of use.
