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 Z535.6-2011, the definitions 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.

SAFETY INSTRUCTIONS (or equivalent) signs indicate specific safety-related instructions of procedures.

2.0 SAFETY

DANGER

An inadequate supply of nozzle pressure and/or flow will cause an ineffective stream and can 

result in injury, death, or loss of property. See flow graphs or call 800-348-2686 for assistance.

WARNING

The  nozzle  may  be  damaged  if  frozen  while  containing  significant  amounts  of  water.  Such 

damage may be difficult 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 qualified personnel 

before being considered safe for use.

WARNING

This  equipment  is  intended  for  use  by  trained  personnel  for  firefighting.  Their  use  for  other 

purposes may involve hazards not addressed by this manual. Seek appropriate guidance and 

training to reduce risk of injury.

WARNING

Failure to restrain nozzle reaction can cause firefighter 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 

flushing will also affect nozzle reaction. The nozzle operator must always be prepared in the 

event of these changes.

WARNING

If nozzle gets out of control or away from operator, retreat from nozzle immediately. Do not 

attempt to regain control of nozzle while flowing water. Injury from whipping can occur.

WARNING

Water is a conductor of electricity. Application of water on high voltage equipment can cause 

injury or death by electrocution. The amount of current that may be carried back to the nozzle 

will depend on the following factors:

•  Voltage of the line or equipment

•  Distance from the nozzle to the line or equipment

•  Size of the stream

•  Whether the stream is solid or broken

•  Purity of the water

CAUTION

Fire streams are capable of injury and damage. Do not direct water stream to cause injury or 

damage to persons or property.
