Small fire apparatus mounted on a pickup-truck-sized chassis, usually with a pump having a rated capacity less than 500 gpm. Its primary advantage is speed and mobility, which enables it to respond to fires more rapidly than larger apparatus.



Apparatus sized between a mini-pumper and a full-sized department pumper, usually with a gross vehicle weight of 12,000 pounds or greater. The _______has a fire pump rated capacity generally not greater than 1,000 gpm.



Apparatus that serves as an engine and as a ladder truck; equipped with a fire pump, water tank, ground ladders, hose bed, and aerial device



Keeping equipment or apparatus in a state of usefulness or readiness.



To restore or put together something that has become inoperable or out of place



Inspecting an apparatus and equipment on the apparatus to ensure that all equipment is in place, clean and ready for service.

Operational Readiness Inspection


A visual inspection of an apparatus to ensure the major components of the chassis are present and in proper working condition.

Pretrip Road Worthiness Inspection


An electrical monitoring system that will shed electrical load in a predetermined order if the chassis voltage begins to drop below a predetermined level.

Load Management System


Operations of equipment or a conductor in excess of its rated ampacity; continuous ____ may result in overheating that damages the equipment.



Device in an electrical system that turns lights on at specified intervals, so that the start-up load for all of the devices does not occur at the same time.

Load Sequencer


Device that "watches" an electrical system for added loads that may threaten to overload the system.

Load Monitor


When an overload condition occurs, the load monitor will shut down less important electrical equipment to prevent the overload.

Load Shedding


Devices used in an air brake system that connect between the activation pads and the brake pads that compensate for brake pad wear.

Slack Adjusters


A specific inspection to an area of a chassis or apparatus to ensure that the unit is operating properly in accordance with the manufacture's initial design.

Post-Maintenance/Repair Inspection


An act of proceeding to do something with a conscious awareness of danger, while ignoring any potential consequences of so doing.

Reckless Disregard


Breach of duty in which a person or organization fails to perform at the standard required by law, or that would be expected by a reasonable person under similar circumstances.



Loss of braking function which occurs due to excessive use of the brakes

Brake Fade


Angle formed by level ground and a line from the point where the front tires touch the ground to the lowest projection at the front of the apparatus.

Angle of Approach


Angle formed by level ground and a line from the point where the rear tires touch the ground to the lowest projection at the rear of the apparatus

Angle of Departure


Angle formed by level ground and a line from the point where the rear tires touch the ground to the bottom on the frame at the wheelbase midpoint

Breakover Angle


Operation where a strong hydrant is used to supply two pumpers by connecting the pumpers intake-to-intake. The second pumper receives the excess water not being pumped by the first pumper, which is directly connected to the water supply source.

Dual Pumping


Short relay operation in which the pumper taking water from the supply source pumps water into the intake of the second pumper; the second pumper then boosts the pressure of the water even higher. This method is used when pressures higher than the capability of a single pump are required.

Tandem Pumping


Ability of an apparatus to traverse a body of standing water. Apparatus specifications should list the specific water depths through which trucks must be able to drive.



Force per unit area exerted by a liquid or gas measured in pounds per square inch (psi) or kilopascals (kPa)



Simple measure of weight, usually expressed in pounds or kilograms.



Force created by the rapid deceleration of water; causes a violent increase in pressure that can be powerful enough to rupture piping or damage fixtures. Generally results from closing a valve or nozzle too quickly.

Water Hammer


Generic term applied to any nozzle, wye, Siamese, deluge monitor, or other piece of hardware used in conjunction with fire hose for the purpose of delivering water.



Self-priming pump that utilizes a piston or interlocking rotors to move a given amount of fluid through the pump chamber with each stroke of the piston or rotation of the rotors. Used for hydraulic pumps on aerial devices' hydraulic systems and for priming pumps on centrifugal fire pumps.

Positive Displacement Pump


Positive-displacement pump using one or more reciprocating pistons to force water from the pump chambers

Piston Pump


Type of positive displacement pump commonly used in hydraulic systems. A rotor with attached vanes is mounted off-center inside the pump housing; pressure is imparted on the water as the space between the rotor and the pump housing wall decreases.

Rotary Vane Pump
