Safety precautions for portable compressor

Introduction

The policy of Atlas Copco is to provide the users of their
equipment with safe, reliable and efficient products.

Factors taken into account are among others:

- the intended and predictable future use of the products, and

the environments in which they are expected to operate,

- applicable rules, codes and regulations,
- the expected useful product life, assuming proper service and

maintenance,

Before handling any product, take time to read the

relevant instruction manual. Besides giving detailed

operating instructions, it also gives specific information
about safety, preventive maintenance, etc.
These precautions are general and some statements will

therefore not always apply to a particular unit.
When handling, operating, overhauling and/or

performing maintenance or repair on Atlas Copco

equipment, the mechanics are expected to use safe
engineering practices and to observe all relevant local

safety requirements and ordinances. The following list is

a reminder of special safety directives and precautions
mainly applicable to Atlas Copco equipment.
This brochure applies to machinery processing or

consuming air. Processing of any other gas requires
additional safety precautions typical to the application

and are not included herein.
All responsibility for any damage or injury resulting from
neglecting these precautions or by non-observance of

ordinary caution and due care required in handling,

operating, maintenance or repair, also if not expressly
mentioned in this instruction manual, is disclaimed by

Atlas Copco.
If any statement does not comply with local legislation,
the stricter of the two shall be applied. Statements in this

manual should not be interpreted as suggestions,

recommendations or inducements that it should be used in
violation of any applicable laws or regulations.

General safety precautions

1 The owner is responsible for maintaining the unit in a

safe operating condition. Unit parts and accessories

must be replaced if missing or unsuitable for safe

operation.

2 Use only lubricating oils and greases recommended or

approved by Atlas Copco or the machine manufacturer.

Ascertain that the selected lubricants comply with all

applicable safety regulations, especially with regard to

explosion or fire risk and the possibility of

decomposition or generation of hazardous gases.

3 The supervisor, or the responsible person, shall at all

times make sure that all instructions regarding

machinery and equipment operation and maintenance

are strictly followed and that the machines with all

accessories and safety devices, as well as the

consuming devices, are in good repair, free of

abnormal wear or abuse, and are not tampered with.

4 Maintenance, overhaul and repair work shall only be

carried out by adequately trained personnel; if

required, under supervision of someone qualified for

the job.

5 Whenever there is an indication or any suspicion that

an internal part of a machine is overheated, the

machine shall be stopped but no inspection covers shall

be opened before sufficient cooling time has elapsed;

this to avoid the risk of spontaneous ignition of oil

vapour when air is admitted.

6 Maintenance work, other than routine attention, shall

only be undertaken when the machine is turned off.

7 Before dismantling any pressurized component, the

compressor or the equipment shall be effectively

isolated from all sources of pressure and be completely

vented to atmosphere. In addition, a warning sign

bearing a legend such as "work in progress; do not

open" shall be attached to each of the isolating valves.

8 Before a machine is being repaired, steps shall be taken

to prevent inadvertent starting. In addition, a warning

sign bearing a legend such as "work in progress; do not

start" shall be attached to the starting equipment. The

battery shall be disconnected and removed or the

terminals covered by insulating caps.

9 Normal ratings (pressures, temperatures, speeds, etc.)

shall be durably marked.

10 Never operate a machine or equipment beyond its rated

limits (pressure, temperature, speed, etc.).

11 Maintenance and repair work should be recorded in an

operator's logbook for all machinery. Frequency and

nature of repairs can reveal unsafe conditions.

12 The machinery and pneumatic equipment shall be kept

clean, i.e. as free as possible from oil, dust or other

deposits.

13 To prevent an increase in working temperature, inspect

and clean heat transfer surfaces (cooler fins,

intercoolers, water jackets, etc.) regularly. For every

machine establish a suitable time interval for cleaning

operations.

14 All regulating and safety devices shall be maintained

with due care to ensure that they function properly.

They may not be bypassed.

15 Care shall be taken to avoid damage to safety valves

and other pressure relief devices, especially to avoid

plugging by paint, oil coke or dirt accumulation, which

could interfere with the functioning of the device.

16 Pressure and temperature gauges shall be checked

regularly with regard to their accuracy. They shall be

replaced whenever outside acceptable tolerances.

17 Parts shall only be replaced by genuine Atlas Copco

replacement parts.

18 Safety devices shall be tested as described in the

maintenance schedule of the instruction book(s) to

determine that they are in good operating condition.

19 Never use flammable solvents or carbon tetrachloride

for cleaning parts. Take safety precautions against

toxic vapors when cleaning parts in or with cleaning

products.

20 Observe scrupulous cleanliness during maintenance

and repair. Keep away dirt by covering the parts and

exposed openings with clean cloth, paper or tape.

21 Protect the engine, alternator, air intake filter, electrical

and regulating components, etc. to prevent moisture

ingress, e.g. when steam-cleaning.

To be read attentively and acted accordingly before towing, lifting, operating, performing maintenance

or repairing the compressor.
