SAFETY

1

1.1 GENERAL

Sullair Corporation and its subsidiaries design and

manufacture all of its products so they can be oper-

ated safely. However, the responsibility for safe op-

eration rests with those who use and maintain these

products. The following safety precautions are of-

fered as a guide which, if conscientiously followed,

will minimize the possibility of accidents throughout

the useful life of this equipment.

The compressor should be operated only by those

who have been trained and delegated to do so, and

who have read and understood this Operator’s

Manual. Failure to follow the instructions, proce-

dures and safety precautions in this manual can re-

sult in accidents and injuries.

NEVER

start the compressor unless it is safe to do

so.

DO NOT

attempt to operate the compressor with

a known unsafe condition. Tag the compressor and

render it inoperative by disconnecting and locking

out all power at source or otherwise disabling its

prime mover so others who may not know of the un-

safe condition cannot attempt to operate it until the

condition is corrected.

Install, use and operate the compressor only in full

compliance with all pertinent OSHA regulations and

all applicable Federal, State, and Local codes, stan-

dards and regulations.

DO NOT

modify the compressor and/or controls in

any way except with written factory approval.

While not specifically applicable to all types of com-

pressors with all types of prime movers, most of the

precautionary statements contained herein are ap-

plicable to most compressors and the concepts be-

hind these statements are generally applicable to all

compressors.

1.2 PERSONAL PROTECTIVE EQUIPMENT

Prior to installing or operating the compressor, own-

ers, employers, and users should become familiar

with, and comply with, all applicable OSHA regula-

tions and any applicable Federal, State and Local

codes, standards, and regulations relative to per-

sonal protective equipment, such as eye and face

protective equipment, respiratory protective equip-

ment, equipment intended to protect the extremi-

ties, protective clothing, protective shields and barri-

ers and electrical protective equipment, as well as

noise exposure administrative and/or engineering

controls and/or personal hearing protective equip-

ment.

1.3 PRESSURE RELEASE

A.

Install an appropriate flow limiting valve between

the service air outlet and the shut--off (throttle)

valve, either at the compressor or at any other point

along the air line, when an air hose exceeding 1/2”

inside diameter is to be connected to the shut--off

(throttle) valve, to reduce pressure in case of hose

failure,

per

OSHA

Standard

29

CFR

1926.302(b)(7).

B.

When the hose is to be used to supply a manifold,

install an additional appropriate flow limiting valve

between the manifold and each air hose exceeding

1/2” inside diameter that is to be connected to the

manifold to reduce pressure in case of hose failure.

C.

Provide an appropriate flow limiting valve at the

beginning of each additional 75 feet of hose in runs

of air hose exceeding 1/2” inside diameter to reduce

pressure in case of hose failure.

D.

Flow limiting valves are listed by pipe size and

rated CFM. Select appropriate valves accordingly,

in accordance with their manufacturer’s recommen-

dations.

E. DO NOT

use air tools that are rated below the

maximum rating of the compressor. Select air tools,

air hoses, pipes, valves, filters, and other fittings ac-

cordingly.

DO NOT

exceed manufacturer’s rated

safe operating pressures for these items.

F.

Secure all hose connections by wire, chain or oth-

er suitable retaining devices to prevent tools or hose

ends from being accidentally disconnected and ex-

pelled.

G.

Open fluid filter cap only when compressor

is not

running and is not pressurized.

Shut down the

compressor and bleed the sump (receiver) to zero

internal pressure before removing the cap.

H.

Vent all internal pressure prior to opening any

line, fitting, hose, valve, drain plug, connection or

other component, such as filters and line oilers, and

before attempting to refill optional air line anti--icer

systems with antifreeze compound.

I.

Keep personnel out of line with and away from the

discharge opening of hoses or tools or other points

of compressed air discharge.

J.

Use air at pressures less than 30 PSIG (207kPa)

for cleaning purposes, and then only with effective

chip guarding and personal protective equipment

per OSHA Standard 29 CFR 1910.242 (b).

K. DO NOT

engage in horseplay with air hoses as

death or serious injury may result.

1.4 FIRE AND EXPLOSION

A.

Clean up spills of lubricant or other combustible

substances immediately, when such spills occur.

B.

Shut off the compressor and allow it to cool. Then

keep sparks, flames and other sources of ignition

away and

DO NOT

permit smoking in the vicinity

when checking or adding lubricant or when refilling

air line anti--icer systems with antifreeze compound.

C. DO NOT

permit fluids, including air line anti--icer

system antifreeze compound or fluid film to accu-

mulate on, under, or around acoustical material, or
