Using Hydrant Boosters

Personnel Required

  • 4 - 5 crew
  • Crew Leader

Equipment required

  • Four 65 mm x 10 m lengths lay flat hose (boosting)
  • Two 65 mm x 30 m lengths lay flat hose (feeding)
  • Three 65 / 65mm controlled breechings
  • WD-40 lubricant (isolation valves)
  • Standpipe
  • Storz spanners
  • Personal protective clothing

Types of Booster Systems

(Thanks to Rick Dawson, Captain, NSW Fire & Rescue, Bega)

There are two types of Booster systems that we may come across - systems installed prior to 1994 and those installed after (known as AS 2419.1). 

Mains Sizes

  • Two boost inlets = 100 mm main
  • Four boost inlets = 150 mm main
  • Six boost inlets = 200 mm
  • Eight boost inlets = 250 mm main.

If there are two boost inlets, you must supply two feeder outlets, etc...

Procedure / Systems prior 1994

With this system, the feed hydrant is separate from the booster assembly. You will find a hydrant situated close to the assembly

 

  • Locate the nearest hydrant to the assembly and ship a standpipe.
  • Attach a 65 to 65 mm controlled breeching to the standpipe. Feed hydrants - (2 lines - 65 mm lay flat)
  • Start the pump and set to idle.
  • Connect Feed Hydrants to Valves 1/2 using a 65 mm controlled dividing breech.
  • Connect Boost inlets to 65 mm Delivery valve using a 65 mm controlled dividing breech. 
  • Open Feed Hydrants and change Valve 1 to 2.
  • Open pump delivery lines. Remember, the pump is in idle mode.
  • Crew Leader informs Incident Controller that the appliance is ready to commence boosting the internal main.
  • Await instructions from the IC to commence boosting
  • The booster is now in Standby Mode.
  • Close the Main Wheel Isolation Valve. All the water is now entering internal mains via the appliance.
  • Slowly and cautiously increase pressure to required level.
  • Maintain pressure.
