SAFETY

3

supplying respirators or other breathing air utiliza-
tion equipment and 

DO NOT 

discharge air from

these systems into unventilated or other confined
areas.

C.

Operate the compressor only in open or ade-

quately ventilated areas.

D.

Locate the compressor or provide a remote inlet

so that it is not likely to ingest exhaust fumes or
other toxic, noxious or corrosive fumes or sub-
stances.

E.

Coolants and lubricants used in this compressor

are typical of the industry. Care should be taken to
avoid accidental ingestion and/or skin contact. In
the event of ingestion, seek medical treatment
promptly. Wash with soap and water in the event of
skin contact. Consult Material Safety Data Sheet for
information pertaining to fluid of fill.

F. 

Wear goggles or a full face shield when adding

antifreeze compound to air line anti-icer systems.

G. 

If air line anti-icer system antifreeze compound

enters the eyes or if fumes irritate the eyes, they
should be washed with large quantities of clean
water for fifteen minutes. A physician, preferably an
eye specialist, should be contacted immediately.

H. DO NOT 

store air line anti-icer system antifreeze

compound in confined areas.

I.

The antifreeze compound used in air line

antifreeze systems contains methanol and is toxic,
harmful or fatal if swallowed. Avoid contact with the
skin or eyes and avoid breathing the fumes. If swal-
lowed, induce vomiting by administering a table-
spoon of salt, in each glass of clean, warm water
until vomit is clear, then administer two teaspoons
of baking soda in a glass of clean water. Have
patient lay down and cover eyes to exclude light.
Call  a physician immediately.

1.8 ELECTRICAL SHOCK

A.

This compressor should be installed and main-

tained in full compliance with all applicable Federal,
State and Local codes, standards and regulations,
including those of the National Electrical Code, and
also including those relative to equipment ground-
ing conductors, and only by personnel that are
trained, qualified and delegated to do so. 

B. 

Keep all parts of the body and any hand-held

tools or other conductive objects away from
exposed live parts of electrical system. Maintain dry
footing, stand on insulating surfaces and 

DO NOT

contact any other portion of the compressor when
making adjustments 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 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 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 hel-
icopter 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 subpart 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

structure has been inspected, is in good condition
and has a rated capacity of at least the  weight of
the compressor. 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 lift-
ed 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.

I. 

Keep lift operator in constant attendance whenev-

er compressor is suspended.

J. 

Set compressor down only on a level surface

capable 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
