– The entire LPG system must be monitored continuously to ensure that it is
in a safe operating condition and, in particular, is not leaking. The vehicle
must not be used if the gas system is leaking.
– The cylinder valve must be closed before disconnecting the pipe or hose
connection. The connection nut on the cylinder must be opened slowly
and only slightly at first, otherwise the gas which is still under pressure in
the line will flow out spontaneously.
Caution:
Liquified gas which comes into contact with skin causes frostbite!
– Following disassembly, the lock nut must be screwed firmly onto the
connecting thread.
– Soap water, a soap bubble solution or other foaming agents should be
used when testing for leaks. It is forbidden to inspect the LPG system
using a naked flame.
– The installation directions of the manufacturer should be observed when
replacing individual system parts. The cylinder and main shut-off valves
should be closed when doing this.
– The condition of the electrical system of LPG vehicles should be monito-
red continuously. Sparks may cause explosions if system parts which
convey gas are leaking. If an LPG vehicle has been stored for a prolonged
period the storage room should be thoroughly ventilated before putting the
vehicle or its electrical systems into operation.
– The Industrial and Commercial Association and the responsible Trade
Supervisory Office must be informed immediately of any accidents which
occur in connection with gas cylinders or the liquified gas system. Dama-
ged components must be kept until the investigation has been concluded.
In storage rooms and in repair workshops
– The storage of power gas and liquefied-gas cylinders must be effected in
accordance with the stipulations of TRF 69 (Technical Regulations for
Liquefied Gas).
– LPG motor vehicles must not be stored in the same room with generator
vehicles.
– The cylinder and main shut-off valves should be closed immediately after
putting the motor vehicle into storage.
– The terms of the relevant legislation on garages and the relevant state
building regulations apply to the location and nature of the storage places
for fuel gas motor vehicles.
– The gas cylinders should be stored in special areas which are separate
from the storage rooms. Refer to “Handling and Storage of Filled Tanks” of
the Technical Principles of the “Statutory Regulation on Pressure Gas”.
– The electrical hand lamps which are used in these places must have a
closed, sealed globe and a rigid basket guard.
– When carrying out work in repair workshops the cylinder and main shut-off
valves should be closed and the fuel gas cylinders protected against heat.
Before interrupting or ending work a responsible person should check
whether all valves, in particular cylinder valves, are closed. Work involving
the use of naked flames, in particular welding and cutting work, must not
be carried out in the vicinity of fuel gas cylinders. Fuel gas cylinders must
not be stored in the workshops, even if they are empty.
– The storage rooms and workshops must be well ventilated. It is important
to remember that fuel gases are heavier than air. They concentrate on the
ground, in repair pits and other floor recesses and may form explosive
gas-air mixtures.
