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 nozzle pressure and/or fl ow will cause an ineff ective stream and can
result in injury, death, or loss of property. See fl ow graphs or call 800-348-2686 for assistance.
The nozzle may be damaged if frozen while containing signifi cant amounts of water. Such
damage may be diffi cult to detect visually and can lead to possible injury or death. Any time the
nozzle is subject to possible damage due to freezing, it must be tested by qualifi ed personnel
before being considered safe for use.
This equipment is intended for use by trained personnel for fi refi ghting. Their use for other
purposes may involve hazards not addressed by this manual. Seek appropriate guidance and
training to reduce risk of injury.
Failure to restrain nozzle reaction can cause fi refi ghter injury from loss of footing and/or stream
protection. Nozzle reaction will vary as supply conditions change: such as opening or closing
other nozzles, hose line kinks, changes in pump settings, etc. Changes in spray pattern or
fl ushing will also aff ect nozzle reaction. The nozzle operator must always be prepared in the
event of these changes.
If nozzle gets out of control or away from operator, retreat from nozzle immediately. Do not
attempt to regain control of nozzle while fl owing water. Injury from whipping can occur.
