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 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.
Messages concerning
property damage A NOTICE concerns property damage only.
DANGER
DANGER indicates a potentially hazardous situation which, ifnot
avoided, will result in death or serious injury.
WARNING
WARNING indicates a potentially 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 for advisory messages concerning possible
property damage, product damage or malfunction, data loss, or
other unwanted results—but not personal injury.

Safety symbols The generic safety alert symbol
calls attention to a potential personal injury hazard. It appears
next to the DANGER, WARNING, and CAUTION signal words
as part of the signal word label. Other symbols may appear next
to DANGER, WARNING, or CAUTION to indicate a specific
type of hazard (for example, fire or electric shock). If other
hazard symbols are used in this document they are identified in
this section.
Additional symbols This document uses the following hazard symbols:
Indicates a safety alert message that concerns a
potential electric shock hazard.
Indicates a safety alert message concerning a
potentially hazardous situation in which you could
fall.
Indicates a safety alert message concerning a
potentially hazardous situation in which you could
be exposed to radio frequency energy.
