Hydrant and Water Supply
Reduced water Volume or pressure from hydrants can result from this situation, such as when demand exceeds system capacity.
Greater demand than the system can provide
THis appliance has one female inlet and multiple male outlets to devide one supply hoseline into two or more lines.
Wye
Applying water to this specific layer in a compartment will reduce radiant heat flux from the upper layer.
Hot Gas Layer
When attacking a vehicle fire, firefighters should extinguish any fire near these compartment first.
Occupant
The three main influences on ground cover fire behavior are fuel type, topography and this..
Weather
Standard fire hydrants must have at least this many 2 1/2" hose outlet nozzles
Two
This type of valve is used in siamese appliances to allow water to flow in only one direction.
Clapper valve
Aiming a solid stream at an item that is on fire unitl it is no longer burning is an example of this attack type.
Direct
This hazard is a primary concern when fighting fires in exterior stacked or piled class A materials.
Collapse
This type of fire is a wind-driven, high-intensity fire that moves through the tops of trees.
Crown fire
This type of hydrant only has water in it when the stem nut is operated to open the control valve, preventing it from freezing in cold climates.
Dry-barrel
This hose lay involves deploying the hose from the water source to the incient scene.
Forward lay
This attack type involves applying water from the outside of the structure to reduce flashover potential and make the environment more survivable for interior crews.
Transitional
Biological waste and aerosol cans are hazards likely to be present in this specific type of fire.
Trash
This is the part of a ground cover fire opposite the head that usually burns slowly and quietly.
Heel
These types of hydrants are usually installed in climates that do no have long periods of below-freezing temperatures.
Wet-barrel
This specific hose load should deploy with fewer kinks and bends than other common loads.
Minuteman
This method of extinguishment involves closing the valve on a natural gas tank to stop the emission of gaseous fuel.
This specific nozzle can safely be used to extinguish fire under the hood of a vehicle.
Piercing nozzle
These are defined as patches of unburned fuel inside the perimeter of a ground cover fire.
Islands
These static water sources, such as lakes, and ponds, may provide water for firefighting through these specific operations.
Drafting
This type of hose stream is created by specialized nozzles such as cellar nozzles, piercing nozzles, or chimney nozzles.
Broken
When perfoming suppression operations in a building protected by automatic sprinklers, the fire department should take this action first.
Supply the FDC
This piece of equipment is designed to prevent damage to fire hose when vehicles must drive over it.
