How do
bushfires technologies work?
As noted before
the main method for controlling a bushfire is using
water.
The water can be
delivered in a number of ways:
- Hoses, self
contained high pressure water tanks.
- Aircraft -
helicopters or fixed wing aircraft.
Hoses are the first line of defence
Helicopters can carry small
amounts of water perhaps to target small out
breaks quickly
water bombing aircraft can
deliver very large quantities of water.(from
waterbomber.com)

Bush
fires are also controlled and partly prevented
by:
- Back burning
in appropriate conditions. This reduces the
amount of potential fuel that could burn out of
control.
- Fire breaks
that are spaces where there are no trees and are
kept clear. This has a similar effect as back
burning but tends to be more permanent.

How does water
extinguish a fire?
Essentially water is effective
because it reduces the access of oxygen to the
fire.
The water hits
the flame and the heat is absorbed in the water
which then disipates as steam
Water blocks access to of oxygen to
the fuel by covering the flame in a layer of water
extinguishing the flame.
