Ball valve
valves used on nozzles, gated wyes, and engine discharge gates. Made up of a ball with a hole in the middle of the ball
combination attack
a type of attack employing both the direct and indirect attack methods
Conduction
is the travel of heat through a solid body
Convection
the travel of heat through the motion of heated matter
convection cycle
as the hot air and gases rise away from the fire, they begin to cool; as they do, they drop down to be reheated and rise again
crosslays
traverse hose beds
direct attack
firefighting operations involving the application of extinguishing agents directly onto the burning fuel
divided hose bed
a hose bed that is separated into two supply hose compartments running the length of the hose bed
double male and double female fittings

Fire tetrahedron
a more advanced concept of combustion includes a fourth element a chemical chain reaction phase
fire triangle
Oxygen, Fuel, Heat
Flashover
the ignition of combustibles in an area heated by convection, radiation, or a combination of the two
hydrant assist valve (HAV)
Also known as a four-way valve
indirect attack
firefighting operations involving the application of extinguishing agents to reduce the buildup of heat released from a fire without applying the agent directly onto the burning fuel
master stream appliance
A large- capacity nozzle that can be supplied by two or more hose lines or fixed piping. it can flow in excess of 350 gallons per minute. includes deck guns and portable ground monitors
Overhaul

standpipe system
a piping arrangement that carries water vertically and sometimes horizontally through a building for firefighting operations. It provides a means of getting water to a fire without long, time-consuming hose stretches.
Standpipe Class I

Standpipe Class II
1.5” connections. Use for first aid firfighting before the fire dept arrives.
Standpipe Class III
Combination of Class i and II. Full scale and first aid fire fighting.
static pressure
the pressure in the water pipe when no water is flowing
Supply hose
the hose used to deliver water from a source to a fire pump
