Safety posters should be changed or rotated regularly

to different working areas to draw attention to them.

The use of tags and labels is not a substitute for

other safety measures, such as locking valves or

removing fuses from a fuse panel. Also, tags or labels

associated with tag-out procedures must never be used

for anything other than their intended purpose.

Remember, once a tag or label is used, it should

only be removed by signed authorization of the

authorizing officer. You should always follow your

command's procedures for logging and recording

tag-out actions.

3 inches wide, painted on the deck.

Operator caution areas, operator working areas,

and observer safe areas are designated for each
