Engineers are the people who drive and operate the
apparatus. The qualifications to become an engineer are
Wisconsin State Certified Firefighter I and Driver
Operator-Pumper. In order for someone to drive and
operate the aerial ladder truck, one must also be
Wisconsin State Certified Driver Operator-Aerial.
The engineers have an important responsibility on all
fire calls of safely getting to the scene in a timely
manner. Once on scene of a working fire, the engineer
must get water to the firefighters on the hose line at
the right pressure. If it is night, the engineer must
also light up the fire scene. Engineers also monitor the
amount of water that is left on the engine in order to
alert crews to back out of a building in case a supply
has not been established. Once a water supply has been
established, the engineer monitors the pressures and
water flow for all the hose lines operating off the
engine to make sure the water supply is adequate for the
amount of fire.
Engineers who operate the aerial
ladder must position the truck in a location that the
stabilizers can be extended and where the ground will
support the weight of the truck. In that position the
aerial ladder must also be able to reach the desired
target without obstruction from trees and wires. The
engineer must also know the load that is carried in the
basket of the ladder for safe operation.
In the
thirty square miles that the Cedarburg Fire Department
covers, only about 10% of that area has a municipal water
system with hydrants. With the hydrants, water supply can
be set up quickly. Typically the first in engine will
attack the fire, while the second engine connects to a
hydrant and supplies the first engine water with 5” hose.
In the other 90% of the area, a water shuttle is
used. On a rural working fire, the first in engine drops
a 5” supply hose on the driveway and then attacks the
fire. The second engine connects to the end of the supply
hose and begins to feed the first in engine with water
from its tank. Once a folding tank arrives and is set up,
water is drafted from the tank by the second engine.
Drafting is the process of lowering the pressure inside
the pump and intake pipes to allow outside atmospheric
pressure to push the water from the folding tank into the
pump. In order to supply the folding tank with water,
tenders are called in from the surrounding departments to
dump water into the tank. The tenders are filled at a
fill site, which is either at a hydrant, dry hydrant
(pipe connected to a pond or stream), or cistern. It is
unlikely that a water source such as a pool or a small
pond on a property would be used because of difficult
access, unknown soil conditions, and small volume.
