SECTION 3 - HANDLING, STORAGE, AND INSTALLATION
Rigging and lifting should only be done by a professional rigger in accordance with a written rig
-
ging and lifting plan. The most appropriate rigging and lifting method will depend on job specific
factors, such as the rigging equipment available and site needs. Therefore, a professional rigger
must determine the rigging and lifting method to be used, and it is beyond the scope of this manual
to specify rigging and lifting details.
