3.6.1
Liabilities of the factory management and
the employee
All persons handling liquid gases are liable to acquaint
themselves with the special properties of the liquid gas-
es for hazard-free handling of operations. The current
documentation is always to be kept on hand.
3.6.2

Maintenance by expert

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 (occupa-
tion accident prevention regulations) "Use of liquid gas"
(BGV D34).
General applicable regulations are the guidelines for in-
specting vehicles whose engines are driven by lique-
fied gases of the Federal Transportation Minister.
3.6.3
Commissioning/Operations
Gas must always be drawn only from one cylinder.
Drawing gas from multiple cylinders simultaneously
can cause liquid gas from one cylinder flowing into the
other. This causes the over-filled cylinder to be subject-
ed to an unpermitted excess pressure when the cylin-
der 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
connection screw points vertically downward).
Perform the replacement of the gas cylinder carefully. Dur-
ing assembly and disassembly, 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 cylinders. Such cylin-
ders are to be emptied by slowly letting out the gas in
open spaces by conforming to all safety regulations
and are to be indicated as leaky. Also inform the issuing
company or its representative (the filling-station atten-
dant) in writing about the damage to the cylinder while
delivering or receiving the cylinders.
Before connecting the gas cylinder, check that its con-
nection 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 cylinders.
Use only dry fire extinguishers (with carbonic acid gas)
in case of fire caused by liquefied gases.
The entire LPG unit must be continuously checked to
ensure that there are no leaks and the unit is function-
ing 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 connec-
tion nut of the gas cylinder slowly because otherwise
the gas under pressure in the tube will flow out instant-
ly.
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 illuminate the LPG unit is strictly prohibited.
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 electrical unit of the
LPG vehicles . Sparks can cause explosions if the gas-
carrying 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 commission-
ing the vehicle or its electrical unit.
Immediately inform the trade association and the con-
cerned trade supervisory authority about accidents with
gas cylinders or LPG units. Store the damaged parts
carefully until all investigations have been completed.
3.6.4
In the installation and storage rooms as
well as the workshops
Propellants or LPG cylinders must always be stored ac-
cording to the regulations of TRF 1996 (Technical Reg-
ulations for Liquid Gases, refer DA to BGV D34,
Appendix 4).
Always store the gas cylinders in a vertical 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 ac-
cess. 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 respective State about the location
and structure of the parking areas for LPG-driven vehi-
cles.
Gas cylinders are to be stored in separate 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
protection cover.
Close all cylinder and main valves before working in re-
pair workshops and protect the gas cylinders against
effect of external heat.
A responsible person must check that all valves, espe-
cially 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 work-
shops must be ventilated properly. Please note that liq-
uefied gases are heavier than atmospheric air. They
get collected on the floor, in recesses and other holes
in the floors and form a gas-air mixture that can lead to
explosions.
