1.0 MEANING OF SAFETY SIGNAL WORDS
A safety related message is identified by a safety alert symbol and a signal word to indicate the level of risk involved with a particular
hazard. Per ANSI Z535.6, the definitions of the four signal words are as follows:
2.0 SAFETY
DANGER
DANGER indicates a hazardous situation which, if not avoided, will result in death or serious injury.
WARNING
WARNING indicates a hazardous situation which, if not avoided, could result in death or serious
injury.
CAUTION
CAUTION indicates a potentially hazardous situation which, if not avoided, could result in minor
or moderate injury.
NOTICE
NOTICE is used to address practices not related to physical injury.
DANGER
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.
WARNING
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.
WARNING
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.
WARNING
Failure to restrain nozzle reaction can cause injury from loss of footing and/or stream protection.
Opening and closing other nozzles, hose line kinks, changes in pump settings, nozzle pattern, or
flushing will cause changes in nozzle reaction. Nozzle operator must always be prepared in the
event of these changes.
WARNING
If nozzle gets out of control while flowing, violent whipping motion will occur. Serious injury or
death could result. Retreat from the nozzle immediately. Do not attempt to regain control of nozzle
while flowing.
WARNING
Application of water or foam solutions on energized electrical equipment could cause
electrocution. Serious injury or death could result. Assume circuits are energized until confirmed to
be de-energized. Do not apply water or foam to energized electrical equipment.
WARNING
The stream exiting a nozzle is 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.
NOTICE
To prevent mechanical damage, do not drop or throw equipment.
