The wwo lengthwise members of a trussed beam which are separated by truss or separation blocks.
Aspirator
A suction device for removing undesirable material from the throat of a victim.
Halyard
Rope used with extension ladders to extend the fly sections.
Cistern
A water storage container, usually below grade level, for emergency use including fire protection.
Turret
A vehicle-mounted master stream device; a heavy stream nozzel mounted on a pumper and connected by piping to the pump. (Also called a turret gun.)
Block and Tackle
The rope and pulley assembly used to obtain a mechanical advantage for hoisting and pulling.
Incipient
The first stage of the burning process with flames confined to the item(s) of origin orior to the ignition of any nearby combustibles.
Condensed
To change a substance to a denser form, as from a gas to a liquid.
Size-Up
A mental process of evaluating all the influencing factors at a fire before committing personnel and equipment to a course of action.
BLEVE
Acronym for Boiling Liquid Expanding Vapor Explosion.
Pressure Regulator
A device used to maintain a constant pressure within a pump while operating.
Gate Valve
A type of control valve with a solid plate operated by a handle and screw mechanism. Operation of the handle moves the plate down into and up out of the waterway.
Wye
A hose appliance to divide oe line into two or more working lines.
Butterfly Valve
A type of control valve that uses a flat baffle operated by a quarter turn handle.
Monitoring
The act of measuring radioactivity to detect and record with monitoring devices the radioactive emissions from a substance; to closely follow radio communication; to record and police operation; to observe and record the activities of an individual performing a function.
Class A Fire
Refers to a fire involving ordingary combustibles such as wood, paper, cloth, and so on.
Torque
A method of measuring usable engine power at the shaft.
Bag Mask
A device used to breathe for a non-breathing person.
Hose Hoist
A metal device having a roller that can be placed over a windowsill or roof's edge to protect a hose and make it easier to hoist.
Fly
The extendable sections (i.e., the upper section or top sections) of an extension or aerial ladder.
Trenching
Strip or trench ventilation is the process of opening a roof area the width of the building with a two foot wide opening to channel out fire and heat.
Building Survey
The portion of the pre-incident planning process during which the company travels to a building and gathers the necessary information to develop a pre-incident plan for the building.
Gooseneck
A slender, curving part of an apparatus; especially for use in hooking something something and thereby attaching to it.
Fire Retardant
A term used to indicate that materials or suvstances have been treated to retard ignition or the spread of fire.
Static Pressure
Stored potential energy that is available to force water through pipes, fittings, fire hoses, and adapters.
Aqueous Film Forming Foam Extinguisher
aqueous film forming foam type extinguishers are rated for use on both Class A and Class B fires. They are not suitable for use in freezing temperatures. An advantage of this type of extinguisher is its ability to coat the liquid surface when used on flammable liquid fires of appreciable depth. This helps to prevent reignition.
Inclement
Bad weather conditions, e.g., stormy, rainy.
Fire Resistive
Refers to material and building design meant to withstand the maximum effect of fire for a specific period of time.
Trumpets
Symbolic insignia of rank used throughout the fire service dating back to the time when fire officers gave commands through speaking trumpets.
Booster Line
A fabric reinforced, rubber-lined hose. Booster hose is generally carried on apparatus on a reel and is used for the initial attack and extinguishment of incipient and smoldering fires. (Also called a red line.)
Incentive
Somethng inciting one to action or effert; stimulus.
Fireproof
The word "fireproof" is a misnomer because it means that something will not burn. Other terms, such a "fire resistant" or "fire retardant" should be used to indicate the degree of resistance to fire, since most items will burn at some temperature.
Riser
A vertical water pipe used to carry water for fire protection systems above grade, such as a standpipe riser, or sprinkler riser.
Brigade
A group of people organized for a specific job or purpose.
Pulley
A wheel with a grooved rim through which a rope or chain is run for hositing or changing the direction of a pulling force.
Class C Fire
Refers to a fire involving energized electrial equipment.
Truss Blocks
The blocks used to separate hte beams of a truss beam ladder. (Also called beam block or rung block.)
Butt Spurs
Metal safety plates attached to the butt end of ground ladder beams.
Make-Up
All actions involved in connecting fire hose or apparatus to other equipment.
Cylinder
A tank or container.
Smoldering
Fire is barely visible, oxygen supply will be reduced to 15% and smoke will be dense. Carbon monoxide and combustible gases are produced and room temperture will rise.
Conflagration
A large, uncontrollable fire covering a cosiderable area and crossing natural fire barries such as streets; usually involves building in more than one block and causes a large fire loss. Forest fires can also be considered conflagrations.
Higbee Indicator
Notches or grooves cut into coupling lugs to identify by touch or sight the exact location of hte Higbee cut.
Differential Dry-Pipe Valve
A valve used in dry-pipe sprinkler systems in which air pressure is used to hold the valve closed and thus hold the water back.
Trussing
The beams, rods, etc., forming a rigid framework for supporting a roof, bridge, etc.
Counterclockwise
In a direction opposite of that in which the hands of clock move.
Relief valve
A spring-loaded decive used to bypass water in a pump when pressures exceed preset operating pressures.
Clockwise
In the direction in which the hands of a clock rotate.
Velocity
rapidity; speed
Flow Pressure
Flow pressure is that forward velocity pressure at a discharged opening while water is flowing.
Hoist
To raise or haul up; lift. An apparatus, such as a crane or winch, for hoisting.
Centrifugal
Force moving to the outside.
Ventilating
The systematic removal of heated air, smoke, and gases from a structure replacing these with cooler air to facilitate fire fighting.
Combustible
Capable of igniting and burning; a combustible substance.
