DANGER indicates a hazardous situation which, if not avoided, will result in death or serious injury.
WARNING indicates a hazardous situation which, if not avoided, could result in death or serious
injury.
CAUTION indicates a potentially hazardous situation which, if not avoided, could result in minor
or moderate injury.
NOTICE is used to address practices not related to physical injury.
An inadequate supply of pressure and/or flow will cause an ineffective stream and can result
in injury or death. Choose operating conditions to deliver adequate fire suppression.
Damage or injury could result from operating this equipment beyond the specified operating
pressure. Do not operate the device at pressures higher than the maximum operating pressure
stated in the specification section.
Kinks in the supply line may reduce water flow, causing injury or death to individuals dependent on
adequate water flow. Always avoid tight bends in the hoseline to minimize kinking.
This equipment is intended for use by trained personnel for firefighting. Use of this equipment for
other purposes may involve hazards not addressed by this manual. Seek appropriate guidance and
training to reduce risk of injury.
Equipment may be damaged if frozen while containing significant amounts of water. Such damage
may be difficult to detect visually. Subsequent pressurization can lead to injury or death. Any time
the equipment is subject to possible damage due to freezing, it must be tested and approved for
use by qualified personnel before being considered safe for use.
Sudden changes in valve position can cause pressure spikes (water hammer) and could lead to
hose or pipe failure or an out of control monitor. Open and close the valve slowly to avoid water
hammer.
Interrupting flow to the device could cause injury or death. Avoid situations that may interrupt
flow to the device such as: hose line kinks, traffic running over hose, and automatic doors or
devices that can pinch the hose.
To prevent mechanical damage, do not drop or throw equipment.
