4.10.1

Warnings and Cautions

Warnings and cautions attract attention to information that is essential to safe

performance; they usually consist of the conditions, design limitations, practices, and

procedures to be complied with to avoid loss of life, personal injury, health hazards, or

damage to equipment. An industry study of significant events attributed one-fourth of all

human performance events to a failure to provide proper warnings and cautions.

[1]

Review potential hazards with facility technical specialists to determine warnings

or cautions that need to be included.

[2]

Determine those parts of the procedure where the addition of information is

necessary.

[3]

Review each action step and list the potential hazards in warning or caution

format.

[4]

Position warnings and cautions so they are complete on one page and appear

immediately before and on the same page as the action step(s) to which they apply.
