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 standard Z535.4-1998 the definitions of the three signal words are as follows:
DANGER
WARNING
CAUTION
2.0 SAFETY
The operation of this monitor, particularly with the portable base can be dangerous.
The following must be observed at all times.
DANGER
DANGER
WARNING
TABLE OF CONTENTS
DANGER indicates an imminently hazardous situation which, if not avoided, will result in death or
serious injury.
WARNING indicates a potentially hazardous situation which, if not avoided, could result in death or
serious injury.
CAUTION indicates a potentially hazardous situation which, if not avoided, may result in minor or
moderate injury.
Low nozzle elevation angles can cause portable monitors to slide or lift off the ground which can
result in injury or death. Do not operate the monitor on the portable base below the elevation safety
stop.
An out of control monitor can cause injury or death. To reduce risk of instability, do not attempt to
move the portable monitor with water flowing.
Injury can occur from an inadequately supported monitor. When the monitor is used on a truck the
mounting must be capable of supporting 900 lbs (400 KG) of nozzle reaction force. Note: the
storage bracket is intended for storage of the monitor only. It is not strong enough to withstand the
forces of monitor operation. Flanges and pipe made from plastic are inadequate for monitor
mounting and must not be used.
