1 Safety Precautions for Portable Compressors
To be read attentively and acted accordingly before towing, lifting, operating,
performing maintenance or repairing the compressor
1.1 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 book. 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 or inert gas. Processing of any other gas
requires additional safety precaution typical to the
application and are not included herein.
All responsibility for any damage or injury resulting from
neglecting these precaution: or by non-observance of
ordinary caution and due care required in handling,
operating, maintenance or repair, also if not expressly
mentioned in this brochure or the instruction book(s), 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.
1.2 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,
including the entire compression or vacuum system with
pipes, valves, connectors, hoses, etc., 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. No inspection covers shall be opened before
sufficient cooling time has elapsed; this is to avoid the risk of
spontaneous ignition of the oil vapor when air is admitted.
6 Maintenance work, other than routine attention, shall only be
undertaken when the machine is standing still.
7 Before dismantling any pressurized component, the
compressor or the equipment shall be effectively isolated
frorn 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
operators 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.
