– Propellant-operated units are to be
checked at regular intervals, at least
once a year, by an expert against leaks
(according to BGG 936) and ensure
that the unit is functioning properly.
– The inspection must be certified and
documented. The inspection guidelines
are § 33 and § 37 UVV (occupation ac-
cident prevention regulations) "Use of
liquid gas" (BGV D34).
– General applicable regulations are the
guidelines for inspecting vehicles
whose engines are driven by liquefied
gases of the Federal Transportation
Minister.
– Gas must always be drawn only from
one cylinder. Drawing gas from multiple
cylinders simultaneously can cause liq-
uid gas from one cylinder flowing into
the other. This causes the over-filled
cylinder to be subjected to an unpermit-
ted excess pressure when the cylinder
valve is closed later (refer B.1 of these
guidelines).
– Ensure the correct positioning of the
cylinder with the "bottom" marking while
connecting a full cylinder (the connec-
tion screw points vertically downward).
Perform the replacement of the gas cylin-
der carefully. During assembly and disas-
sembly, the gas outlet nozzle of the
cylinder valve must be sealed by means of
a cap nut that is tightened using a wrench.
– Discontinue the use of leaky gas cylin-
ders. Such cylinders are to be emptied
by slowly letting out the gas in open
spaces by conforming to all safety reg-
ulations and are to be indicated as
leaky. Also inform the issuing company
or its representative (the filling-station
attendant) in writing about the damage
to the cylinder while delivering or re-
ceiving the cylinders.
– Before connecting the gas cylinder,
check that its connection neck is in a
proper state.
– After connecting the cylinder, regularly
check that it is not leaky by using a
foaming agent.
– Open the valves slowly. Do not use
hammers to open and close the cylin-
ders.
– Fight liquid-gas fires only from a safe
distance and with protection.
- use only dry powder carbon dioxide
extinguishers or carbon dioxide gas ex-
tinguishers.
- use abundant water to cool the gas
tank.
– The entire LPG unit must be continu-
ously checked to ensure that there are
no leaks and the unit is functioning
properly. Using the vehicle with a leaky
gas unit is strictly prohibited.
– First close the cylinder valve before
loosening the pipe or tube connection.
Unscrew and loosen the connection nut
of the gas cylinder slowly because oth-
erwise the gas under pressure in the
tube will flow out instantly.
– If the gas is refilled from a larger tank,
then ask the sales agent of the LPG
about the important regulations to be
followed.

Danger
Risk of injury!
– LPG in a liquid state can cause frost
bites on bare skin.
– After disconnecting the cylinder, tighten
the closing nut firmly on the connecting
threading of the cylinder.
– Use soap water or some such foaming
agent to check whether the cylinder is
leaking. The use of open flames to illu-
minate the LPG unit is strictly prohibit-
ed.
– Follow the manufacturer's installation
specifications while changing individual
parts of the LPG unit. Close all cylinder
and locking valves while doing so.
– Regularly check the status of the elec-
trical unit of the LPG vehicles . Sparks
can cause explosions if the gas-carry-
ing parts of the unit are leaky.
– If a LPG-driven vehicle has been idling
for a long time, then first ventilate the
setting room before commissioning the
vehicle or its electrical unit.
– Immediately inform the trade associa-
tion and the concerned trade superviso-
ry authority about accidents with gas
cylinders or LPG units. Store the dam-
aged parts carefully until all investiga-
tions have been completed.
– Propellants or LPG cylinders must al-
ways be stored according to the regula-
tions of TRF 1996 (Technical
Regulations for Liquid Gases, refer DA
to BGV D34, Appendix 4).
– Always store the gas cylinders in a ver-
tical position. Use of open flames and
smoking at the installation site of the
cylinders and during repairs is strictly
prohibited. Protect the stored cylinders
against unauthorised access. Close all
empty cylinders properly.
– Close the cylinder and main locking
valves immediately when you switch off
the vehicle.
– Follow the regulations for garages and
the construction guidelines of the re-
spective State about the location and
structure of the parking areas for LPG-
driven vehicles.
– Gas cylinders are to be stored in sepa-
rate rooms away from the parking areas
(refer DA to BGV D34, Appendix 2).
– The electrical hand-held lamps used in
the rooms are to be equipped with
closed, sealed case and a strong pro-
tection cover.
– Close all cylinder and main valves be-
fore working in repair workshops and
protect the gas cylinders against effect
of external heat.
– A responsible person must check that
all valves, especially the cylinder
valves, are closed during operational
breaks and before closing the factory.
Do not carry out any jobs involving fire -
such as cutting and welding jobs - in the
vicinity of the gas cylinders. Do not
store gas cylinders, not even empty
ones, in the workshops.
– The parking and storage rooms and the
repair workshops must be ventilated
properly. Please note that liquefied gas-
es are heavier than atmospheric air.
They get collected on the floor, in re-
cesses and other holes in the floors and
form a gas-air mixture that can lead to
explosions.
