Warnings
Risk of accident and injury!
Risk of accident and injury due to non-functioning or improperly used safety
devices!
Serious injury to persons and damage due to water hammer effect!
If water delivery via a pipe or hose is interrupted abruptly, a pressure impact
known as the water hammer effect occurs; this is noticeable as a harsh
noise (like a hammer hitting a pipe). This water hammer can cause severe
injury when handling fire-fighting equipment, as well as damage to lines,
hoses, pumps, valves or other pieces of equipment.
Risk of death due to electric shock!
Water, fire fighting foam and metallic components conduct electricity.
WARNING!
Do not bypass safety and protective equipment.
Do not tamper with or render ineffective safety and protective
equipment.
Check safety and protective equipment is functioning properly.
Perform adjustments of nozzles, hydrants, valves etc. slowly.
Before opening a discharge outlet, keep a tight hold on the tips and
nozzles.
Release pressure before disconnecting any hose.
Actuate valves slowly to avoid pressure impacts.
In case of danger for persons (e.g. due to a burst hose) immediately
reduce the pump speed or close the affected discharge outlet. Switch
off the pump system if needed.
Do not point turrets or nozzles (extinguishing agent jet) directly at high
voltage lines or other electrical installations.
Observe the safety distance from live parts at all times.
Foam ban for firefighting involving electrical systems.
Never park vehicle under or near overhead lines.
Take special care with vehicles with roof structures, e.g. extendable
light mast or turret.
Do not handle or use metal ladders near high voltage lines or other
electrical installations.
Only extinguish live systems or system components in compliance with
VDE 0132.
