Presentation Transcript
water sources for fire fighting
WATER SOURCES FOR FIRE FIGHTING
  • Municipal water systems
  • Private water systems
  • Natural supplies
  • Manmade sources

Water Supply

fire hydrants
FIRE HYDRANTS

Wet barrel

Used in warm climates

Water is always in the barrel

Operating nut at each outlet and on bonnet

Dry barrel

Used in cold climates (Georgia)

Water not in barrel

Operating nut on top of bonnet

Water Supply

connecting to a fire hydrant 2 outlet
CONNECTING TO A FIRE HYDRANT 2½” Outlet
  • Take needed equipment
  • Wrap hose one turn around hydrant
    • Place foot on hose & signal driver to lay hose
  • Place hydrant wrench on operating nut
  • Remove caps from outlet(s) to be used
  • Open hydrant to flush debris (10-20 sec.)
  • Close hydrant
  • Attach hose(s) to hydrant outlet facing fire
    • Attach valve to not-used 2½” outlet
  • Fully open hydrant on signal from pumper operator
  • After use close hydrant

Water Supply

hose lays
HOSE LAYS
  • Forward lay
    • Female coupling off truck first

Water Supply

hose lays6
HOSE LAYS
  • Reverse lay
    • Male coupling off truck first

Water Supply

hydrant maintenance
HYDRANT MAINTENANCE
  • As required locally
    • Obstructions to hydrant
    • Obvious damage
    • Rust and corrosion
    • Caps removable
    • Hydrant operational
      • Lubricate

Water Supply

drafting
DRAFTING

The process by which water is lifted by means of a vacuum from a static water source into a pump

Water Supply

equipment needed for drafting
EQUIPMENT NEEDED FOR DRAFTING
  • Pumper
  • Hard suction
  • hose
  • Strainer
  • Mallet

Water Supply

portable water tank
PORTABLE WATER TANK

A portable device that serves as a temporary reservoir for water

Folding Frame

Self-supporting

Water Supply

transfering water between portable tanks
TRANSFERING WATER BETWEEN PORTABLE TANKS
  • Simple Siphon Method
    • Utilizing a hard suction hose or other non-collapsible tube or pipe to allow water to flow from one portable tank to another by atmospheric pressure

Water Supply

mobile water supply operations
MOBILE WATER SUPPLY OPERATIONS

A method of transporting water from a water source to a fire attack apparatus by use of tankers, pumpers, or other apparatus

Water Supply

mobile water supply operations procedure
MOBILE WATER SUPPLY OPERATIONS Procedure
  • Supply apparatus transports water to the fire attack pumper
  • Supply apparatus off-loads water:
    • Supply apparatus pumps directly into tank on pumper
    • Pumper drafts directly from the supply apparatus
    • Water off-loaded into portable tank
  • After unloaded, supply apparatus goes to fill point
  • Supply apparatus is filled with water
  • Supply apparatus returns to fire attack pumper
  • Cycle is repeated

Water Supply

relay pumping operation
RELAY PUMPING OPERATION
  • A method of moving water a long distances by the use of two or more apparatus where as one apparatus pumps water to the next
  • May be needed when the length of hose line from the water source to the attack apparatus is such that there is insufficient water/pressure to provide the required fire flow

Water Supply

relay pumping operation procedures
RELAY PUMPING OPERATION PROCEDURES
  • Apparatus are spaced from the incident to the water source
  • Hose lines are laid from apparatus to apparatus
  • Pumping apparatus sets up at the water source
  • First Apparatus pumps from water source to the intake of the next pumper
  • The second apparatus pumps to the next and so on
  • The last apparatus will be operating at the scene
  • Operation can consist of as few as two apparatus or as many as required
