Understanding safety alert messages
Safety alert messages call attention to potential safety hazards and tell you how to
avoid them. These messages are identified by the signal words DANGER, WARNING,
CAUTION, or NOTICE, as illustrated below. To avoid possible property damage,
personal injury, or in some cases possible death, read and comply with all safety
alert messages.
Messages concerning personal injury
The signal words DANGER, WARNING, and CAUTION indicate hazards that could
result in personal injury or in some cases death, as explained below. Each of these
signal words indicates the severity of the potential hazard.
CAUTION indicates a potentially hazardous situation which, if not avoided,
could result in minor or moderate injury.
Messages concerning property damage
A NOTICE concerns property damage only.
NOTICE is used for advisory messages concerning possible property damage,
product damage or malfunction, data loss, or other unwanted results—but
not personal injury.
