2 Safety
2.1 General Safety !!! WARNING !!!
COMPRESSED GAS IS A HIGHLY DANGEROUS
SUBSTANCE
READ AND UNDERSTAND THIS SECTION OF
MANUALS
IT IS ESSENTIAL FOR THE SAFE OPERATION
OF EQUIPMENT
2.1.1. Systems must be entirely vented before repair or maintenance is carried
out.
2.1.2. The installation, operation, maintenance and repair shall be carried out
only by qualified personnel and in accordance with the corresponding
regulations for operation and safety.
2.1.3. No smoking or naked lights within 10m of any gas installation.
2.1.4. Do not adjust, remove or bypass any protective device.
2.1.5. Rotating machine parts represent a special danger. Covers and guards
must not be removed whilst the machine is operating.
2.1.6. Persons operating the compressor should use hearing protection.
2.1.7. Do not store flammable materials e.g. oily rags near the compressor
unit or engine drive.
2.1.8. Supply pipework and other components, which may not be included in
scope of supply, must be suitable for the respective working pressure.
2.1.9. If necessary they have to be tested and protected by a pressure-
unloading device.
2.1.10.Electrical cable must be Flameproof and must not be linked, or allowed
to contact rotating parts.

2.2 Maintenance Safety
!!! WARNING !!!
COMPRESSED GAS IS A HIGHLY
DANGEROUS SUBSTANCE.
BEFORE DISMANTING ANY PART OF
THE COMPRESSOR, ENSURE THAT THE
UNIT IS COMPLETELY DEPRESSURED
2.2.1. Maintenance and repair may be carried out only on the shutdown and
entirely vented compressor unit. If necessary isolate all storage
systems and blow-down all condensate traps and heat exchanger
collectors. Open all manual drain valves.
2.2.2. Isolate the equipment electrically by pad-locking the main switch in the
"OFF" position and fixing a corresponding warning sign.
2.2.3. Only use original spare parts and recommended products for
maintenance and repair works on the compressor unit.
2.2.4. Never do work that will produce heat, like welding near oil or gas
systems. Before working on oil or gas tanks empty them and clean
them carefully eg. by a steam jet or purge with nitrogen.
2.2.5. During maintenance and repair work observe strict cleanliness. Keep
impurities away, by covering dismounted parts and free openings with
a clean rag, paper or adhesive tape.
2.2.6. After having finished the works be sure that no tools, loose parts or
cleaning rags have been left on or in the compressor unit, or near the
engine air cleaner.
2.2.7. Do not use easily flammable solving agents for cleaning of parts, until
the unit has cooled thoroughly. After the use of solving agents
carefully rinse the parts and clean them with compressed air.
2.2.8. Be very careful, use eye protection, when working with compressed air
for cleaning equipment.
2.2.9. After modification or repair work on pressure vessels and safety
equipment, such as relief valves, all work must be tested and accepted
by the inspection authority concerned.
2.2.10.The switchboard may be opened only by qualified and authorized
persons. Even if the main switch is set to the "OFF" position, the poles
of the switch and feed cables of the terminal strip are alive. Therefore
do not touch anything on the switchboard, and do not carry out work,
with the mains current supply is not disconnected. Before starting
work check if the system is entirely free of power.
Intermech Ltd. BBR-6015-2 Compressor Service Manual

Page 12 of 85
2.2.11.Do not touch bare wires and live (current-carrying) parts, when the
electrical system is energized.
2.2.12.After modification or repair work to compressor, and before power is
supplied to machine, always manually turn compressor over by hand to
ensure compressor is running free.
2.2.13.Intermech takes no responsibility for personal injury or damage on the
unit, caused by the non-observance of the safety precautions during
handling, operation, maintenance or repair of compressor units or other
equipment.
