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.

symbols may appear next to DANGER, WARNING, or CAUTION to indicate a specific type of hazard (for
