2.11 SAFETY MEASURES IN NORMAL OPERATION
•
Before switching on the pressure device, ensure that no-one can be put in a situation of danger due to
the pressure device start-up.
•
Check the pressure device for leaks and correct function of safety equipment at least once annually.
2.12 DANGER FROM ELECTRICITY
•
Have work on electrical components, display units and control units carried out only by a trained
electrician.
•
Check the electrical equipment of the system regularly. Rectify loose connections and damaged cable
immediately.
•
The switch cabinet and the electrical units must be kept closed. Access is restricted to authorized
personnel with key or tools.
2.13 DANGER FROM PRESSURE
•
Sections of the system and pressure lines which are to be opened must be depressurized before starting
repair work.
•
External influences such as high temperatures, heat radiation, impact and similar can cause gas
cylinders or pressurized parts of the system to heat up excessively or burst. Please take the appropriate
precautionary and safety measures.
2.14 PARTICULAR DANGERS FROM OUTWARD LEAKAGE
•
If very hazardous, hazardous or slightly hazardous gases are used, leaks from the pressure device can
cause danger to life and limb of the user.
•
Therefore, a directive according to § 20 GefStoffV, a current EU safety data sheet according to § 14
GefStoffV and accident instructions with information for the doctor must be kept at a suitable place.
•
Operators must be informed of the particular dangers associated with the gas and of any personal or
other protective measures.
2.15 INFORMATION ON SPECIAL GAS TYPES
•
All parts which come into contact with oxygen must be absolutely free of oil and grease, danger of fire
and explosion!
•
Use only lubricants with oxygen approval.
•
Please use special pressure regulators for corrosive, reactive or flammable gases or gas mixtures like
cylinder pressure regulator FMD 500/502-21 with external purging device.
2.16 EMISSION OF HARMFUL GASES AND VAPOURS
•
When safety equipment is open, or in case of malfunctions, harmful gases can escape (see above).
•
Ensure sufficient ventilation or extraction. Take special precautionary measures with dangerous media.
In particular, lead off relief valve and purge valve via rigid pipework and dispose of the substances in a
safety-conscious and environmentally responsible manner.
2.17 SERVICING AND MAINTENANCE, RECTIFICATION OF MALFUNCTIONS
•
Have prescribed setting, servicing and inspection work carried out punctually by the manufacturer or by
a specialist authorized firm.
•
Inform operating personnel and users before servicing and maintenance work starts.
•
All upstream and downstream equipment required for controlling the pressure devices and/or the system,
such as compressed air and hydraulic systems, must be secured against unauthorized start-up.
•
Before all servicing, maintenance and repair work, the associated equipment must be switched off
electrically. The main switch must be secured against unauthorized start-up.
•
Lock the main switch and remove the key.
•
Attach a warning sign to prevent it being switched on.
•
Check tightness of screwed connections which were released.
•
Check function of safety equipment after completion of servicing work.
2.18 CONSTRUCTIONAL ALTERATIONS TO THE PRESSURE DEVICE OR THE
SYSTEM
•
Do not make changes, additions or alterations to the pressure device without written approval from the
manufacturer.
•
Parts of the system which are not in perfect working order must be replaced immediately.
•
Use only original spare parts and wearing parts.
2.19 CLEANING PRESSURE DEVICES AND DISPOSING OF RESIDUES
Pressure devices which have been used and are awaiting repair must be purged with an inert gas (nitrogen,
argon). Solid gas residues must be handled and disposed of correctly. In particular, do not contaminate with
