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. See flow
graphs.
Injury or damage can occur from an inadequately supported monitor. The mounting must be
capable of supporting the nozzle reaction force which can be as high as 1500 lbs.
The stream exiting a nozzle is very powerful and capable of causing injury and property damage.
Make sure the nozzle is securely attached and pointing in a safe direction before water is turned
on. Do not direct water stream to cause injury or damage to persons or property.
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
On many vehicle installations, the monitor is the highest point on the apparatus. Damage or
injury could occur if there is not sufficient clearance to safely pass under doors or overhead
obstructions. Always check parked position of the monitor before moving.
The electric drives are current limited but may still produce enough force to cause injury. To avoid
injury from a moving monitor:
• Be aware that the monitor may be remotely operated
• Keep hands and fingers away from pinch points on the monitor
• Never operate the manual override while electric controls are in operation
