SAFETY MESSAGES
General
The importance of safe operation and maintenance cannot
be overemphasized. Carelessness or neglect on the part of
operators, job supervisors and planners, rigging personnel,
and job site workers can result in their death or injury and
costly damage to the crane and property.
To alert personnel to hazardous operating practices and
maintenance procedures, safety messages are used
throughout the manual. Each safety message contains a
safety alert symbol and a signal word to identify the hazard’s
degree of seriousness.
