Lifting; Entrapment - Sullair SN55 User Manual

ments or repairs to exposed live parts of the electrical
system. Make all such adjustments or repairs with
one hand only, so as to minimize the possibility of
creating a current path through the heart.
C. Attempt repairs in clean, dry and well lighted and
ventilated areas only.
D. DO NOT leave the compressor unattended with open
electrical enclosures. If necessary to do so, then discon-
nect, 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.
All field equipment must be tested for electro-
static fields prior to servicing or making contact
with the machine using the following or equiva-
lent test equipment:
• 90 – 600 VAC: Volt detector such as Fluke
Model 1AC-A
• 600 – 7000 VAC: Voltage detector such as
Fluke Networks Model C9970
It is the responsibility of each organization to
provide/arrange training for all their associates
expected to test for electrostatic fields.

1.9 Lifting

A. If the compressor is provided with a lifting bail, then
lift by the bail provided. If no bail is provided, then lift
by sling. Compressors to be air-lifted by helicopter
must not be supported by the lifting bail but by slings
instead. In any event, lift and/or handle only in full
compliance with OSHA standards 29 CFR 1910 sub-
part N and/or any applicable Federal, State, and
Local codes, standards and regulations.
B. Inspect 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 struc-
ture has been inspected, is in good condition and has
a rated capacity of at least the weight of the com-
pressor. If you are unsure of the weight, then weigh
compressor 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 compressor 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
compressor whenever it is suspended.
H. Lift compressor no higher than necessary.
Keep lift operator in constant attendance whenever
I.
compressor is suspended.
J. Set compressor down only on a level surface capa-
ble of safely supporting at least its weight and its
loading unit.
K. When moving the compressor by forklift truck, utilize
fork pockets if provided. Otherwise, utilize pallet if
provided. If neither fork pockets or pallet are pro-
vided, then make sure compressor is secure and well
balanced on forks before attempting to raise or trans-
port it any significant distance.
L. Make sure forklift truck forks are fully engaged and
tipped back prior to lifting or transporting the com-
pressor.
M. Forklift no higher than necessary to clear obstacles
at floor level and transport and corner at minimum
practical speeds.
N. Make sure pallet-mounted compressors are firmly
bolted or otherwise secured to the pallet prior to
attempting to forklift or transport them. NEVER
attempt to forklift a compressor that is not secured to
its pallet, as uneven floors or sudden stops may
cause the compressor to tumble off, possibly causing
serious injury or property damage in the process.

1.10 Entrapment

A. If the compressor enclosure, if any, is large enough
to hold a man and if it is necessary to enter it to per-
form service 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 of compressor
before closing and latching enclosure doors.
