with open electrical enclosures. If necessary to do
so, then disconnect, lock out and tag all power at
source so others will not inadvertently restore
power.
E. Disconnect, lock out, and tag all power at source
prior to attempting repairs or adjustments to rotating
machinery and prior to handling any ungrounded
conductors.
1.9 LIFTING
A. If the Vacuum System is provided with a lifting
bail, then lift by the bail provided. If no bail is pro-
vided then lift by sling. Vacuum Systems to be air
lifted by helicopter must not be supported by the lift-
ing bail, but by slings instead. In any event, lift only
in full compliance with OSHA Standards 29 CFR
1910 subpart N.
B. Inspect lifting bail and points of attachment for
cracked welds and for cracked, bent, corroded or
otherwise degraded members and for loose bolts or
nuts prior to lifting.
C. Make sure entire lifting, rigging and supporting
structure has been inspected, is in good conditions
and has a rated capacity of at least the weight of the
Vacuum System. If you are unsure of the weight,
then weigh the Vacuum System before lifting.
D. Make sure lifting hook has a functional safety
latch or equivalent, and is fully engaged and latched
on the bail or slings.
E. Use guide ropes or equivalent to prevent twisting
or swinging of the machine once it has been lifted
clear of the ground.
F. DO NOT attempt to lift in high winds.
G. Keep all personnel out from under and away
from the Vacuum System when it is suspended.
H. Lift Vacuum System no higher than necessary.
I. Keep lift operator in constant attendance whenev-
er Vacuum System is suspended.
J. Set Vacuum System down only on level surfaces
capable of supporting at least its weight and unit
loading.
K. When moving Vacuum System by forklift truck,
utilize fork pockets if provided. If neither fork pock-
ets or pallet are provided, then make sure machine
is secure and well balanced on forks before
attempting to raise or transport it any significant dis-
tance.
L. Make sure forklift truck forks are fully engaged
and tipped back prior to lifting or transporting the
Vacuum System.
M. Forklift no height than necessary to clear obsta-
cles at floor level, and transport and corner at mini-
mum practical speeds.
N. Make sure pallet mounted Vacuum Systems are
firmly bolted or otherwise secured to the pallet prior
to attempting to forklift or transport them. Never
attempt to forklift a Vacuum System that is not
secured to its pallet, as uneven floors or sudden
stops may cause the Vacuum System to tumble off,
possibly causing serious injury or property damage
in the process.
1.10 ENTRAPMENT
A. If the Vacuum System enclosure, if any, is large
enough to hold a person, and it it is necessary to
enter it to perform service or adjustments, inform
other personnel before doing so, or else secure and
tag the access door in the open position to avoid the
possibility of others closing and possibly latching
the door with personnel inside.
B. Make sure all personnel are out Vacuum System
before closing and latching enclosure doors.
