Pump Panel Operation
CAUTION !
- Before opening a handline discharge valve make sure that the
nozzles are held tightly - danger of water hammer effect!
- Release pressure before disconnecting a hose!
CAUTION !
Do not operate the pump with closed pressure outlets - dangerous
increase of temperature will result!
Water and foam compounds are conducting electricity!
Remain a safe distance from electricity conductors!
Some materials will increase in volume and/or weight when mixed
with water.
Because of the possibility of chemical reactions, some materials
must not come into contact with water!
FAILURE TO FOLLOW THIS PROCEDURE COULD CAUSE
PERSONAL INJURY!
When the flow of water through the fire hose or pipe is suddenly
stopped, the resulting surge is referred to as "water hammer".
Water hammer can often be heard as a distinct, sharp clank, very
much like a hammer striking a pipe. This sudden stoppage results
in a change in the direction of energy and this energy is instanta-
neously multiplied many times. These excessive pressures can
cause considerable damage to water mains, plumbing, fire hoses,
and fire pumps.
Nozzle controls, hydrants, and valves should be operated slowly to
prevent water hammer.
Use nozzles for fire fighting purposes only.
Never aim the jet at people.
