Meaning Of Safety Signal Words - Task Force Tips SAFE-TAK 1250 Operation And Maintenance Instructions

1.0 MEANING OF SAFETY SIGNAL WORDS

A safety related message is identifi ed by a safety alert symbol and a signal word to indicate the level of risk involved with a particular
hazard. Per ANSI standard Z535.6-2011, the defi nitions of the four signal words are as follows:
DANGER
WARNING
CAUTION
NOTICE
2.0 SAFETY
The operation of this monitor, particularly with the portable base can be dangerous.
The following must be observed at all times.
An inadequate supply of nozzle pressure and/or fl ow will cause an ineff ective stream and can
DANGER
result in injury, death, or loss of property. See fl ow graphs in section 3.0 or call 800-348-2686 for
assistance.
DANGER
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 the risk of instability, do not
DANGER
attempt to move the monitor with water fl owing.
Injury can occur from an inadequately supported monitor. When the monitor is used on a truck
WARNING
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.
A sliding monitor can cause injury. To protect against sliding:
WARNING
An unstable monitor can cause injury. If the safety valve trips, shut off the water to the monitor,
WARNING
correct the instability that caused the safety valve to trip, and only then reset the safety valve.
Do not attempt to reset the safety valve while fl owing.
The fl ow from the monitor may be vital to keep a fi refi ghter from injury or death. Avoid situations
WARNING
that may interrupt fl ow to the monitor such as: hose line kinks, traffi c running over hose, and
automatic doors or devices that can pinch the hose.
Some volatile liquids can be ignited by static discharge. Static build-up can occur from:

each use. The service life of the nozzle may be shortened due to the eff ects of corrosion and is
not covered under warranty.
Master streams are powerful and capable of causing injury and property damage. Make sure the

monitor is pointing in a safe direction before water to the nozzle is turned on. Use care in directing
the stream.

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.
Low nozzle elevation angles can cause portable monitors to slide or lift off the ground which
• make sure the base legs are locked in position with all leg spikes in contact with the ground.
• securely tie the monitor to an object capable of withstanding 900 lbs (400 kg) of force.
• use additional tie downs on hard surfaces such as concrete, asphalt, and metal.
• avoid lifting the monitor when moving the hoses around it.
• Electrochemical separation of charge as water drains through low conductivity, refi ned
products.
• Applying foam over a low conductivity liquid of suffi cient depth to retain the charge created
as the foam blanket drains.
• Streaming currents as water or foam is introduced into the storage tank.1
