1.0 MEANING OF SAFETY SIGNAL WORDS
A safety related message is identi
fi
ed 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 de
fi
nitions of the four signal words are as follows:
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.
2.0 SAFETY
DANGER
An inadequate supply of pressure and/or
fl
ow will cause an ine
ff
ective stream and can result
in injury or death. Choose operating conditions to deliver adequate
fi
re suppression. See
fl
ow
graphs.
WARNING
This equipment is intended for use by trained personnel for
fi
re
fi
ghting. 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 signi
fi
cant amounts of water. Such
damage may be di
ffi
cult 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 quali
fi
ed personnel before being considered safe for use.
WARNING
Failure to restrain nozzle reaction can cause
fi
re
fi
ghter injury from loss of footing and/or stream
protection. Opening and closing other nozzles, hose line kinks, changes in pump settings, nozzle
pattern, or
fl
ushing 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
fl
owing, 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
fl
owing.
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 con
fi
rmed
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.
