ADMONISHMENTS
Important safety admonishments are used throughout this manual to warn of possible hazards
to persons or equipment. An admonishment identifies a possible hazard and then explains
what may happen if the hazard is not avoided. The admonishments — in the form of Dangers,
Warnings, and Cautions — must be followed at all times. These warnings are flagged by use
of the triangular alert icon (seen below), and are listed in descending order of severity of
injury or damage and likelihood of occurrence.
Danger: Danger is used to indicate the presence of a hazard that will cause severe personal
injury, death, or substantial property damage if the hazard is not avoided.
Warning: Warning is used to indicate the presence of a hazard that can cause severe
personal injury, death, or substantial property damage if the hazard is not avoided.
Caution: Caution is used to indicate the presence of a hazard that will or can cause minor
personal injury or property damage if the hazard is not avoided.
