RECOMMENDED PRACTICES - ELECTRIC POWERED HOISTS
Because
R&M Materials Handling, Inc.
has no direct control over the hoist and its operation, conformance with
good safety practice is the responsibility of the user and operating personnel. ANSI/ASME B30.16 has been
used as a guide in preparing this list of
SHALLs
and
SHALL NOTs
. Ask your supervisor for a copy. Each is
identified according to
ANSI / NEMA Z535.4
with either the signal word
CAUTION
or
WARNING
to indicate the
degree of seriousness

operate beyond the limits of the load chain
travel.
