cured during lifting and rigging by
temporary supports and restraints until
equipment is permanently fastened and
set in its final location.
All unit temporary and permanent sup-
ports must be capable of safely sup-
porting the equipment’s weight and any
additional live or dead loads that may
be encountered. All supports must be
designed to meet applicable local codes
and ordinances.
