General safety rules for the use of liquid gas facilities
Inspection of the gas system
• Have the gas system checked by an expert before the first use.
• The testing of the gas system and chimneys is to be repeated regularly
by a liquid gas expert according to the national regulations (eg in Ger
-
many every 2 years). This inspection should be documented on the
inspection certificate in accordance with the German Association
of Gas and Water Experts, worksheet G 607, and EN 1949.
• Regulator knobs, hoses and waste gas outlets should also be
inspected.
• The safety regulators and hose lines must be replaced at least every
10 years; high-pressure hoses after 5 years (from the date they were
manufactured. Should you discover tears, porous spots or similar de
-
fects in the hose, it must be replaced immediately.
• The owner/operator is responsible for arranging the inspection.
This also applies for vehicles that are not licensed to drive on public
roads.
The gas operation pressure is
30 mbar.
If you suspect that gas is leaking, take the following
measures immediately:
• Close the stop valve on the gas bottle.
• Ignition sources such as open flames or smoking
are strictly forbidden.
• Air the rooms.
• Clear the danger zone.
• Inform your immediate surroundings (groundsman)
and, if necessary, the fire brigade.
The gas fittings may only be taken into operation
again after they have been checked by an expert.
Installations and modifications
• Fixtures and changes to the gas system may only be carried out
by a recognised expert for liquid gas systems.
• Only devices with a uniform inlet pressure of 30 mbar may be
operated.
• Any change in the gas system requires a new inspection by an
expert and a gas safety certificate.
