Safety regulations for LPG vehicles
Hauptverband der gewerblichen Beruf-
sgenossenschaften e.V. (HVBG / Germa-
ny). Liquefied gases (propellants) are bu-
tane and propane or a mixture of butane/
propane. They are available in special cyl-
inders. The operating pressure of these
gases depends on the outside tempera-
ture.
Danger
Risk of explosion! Do not handle liquified
gas like petrol. Petrol evaporates slowly,
liquified gas immediately turns into gas.
The risk of gas spreading in the room and
getting ignited is thus higher in case of liq-
uefied gas than in petrol.
Danger
Risk of injury! Use only liquefied gas cylin-
ders with propellant filled according to DIN
51622 of A or B quality, depending on the
surrounding temperature.
CAUTION
Use of cooking gas is strictly prohibited. For
the gas engine, use only liquid gas mix-
tures of propane/ butane or their mixtures
where the mixing ratio lies between 90/10
to 30/70. On account of better cold start be-
haviour even at low outside sub-zero tem-
peratures (below 0° C / 32 °F) always pre-
fer a mixture with a higher propane share
because evaporation takes place even at
low temperatures.
Liabilities of the factory management
and the employee
– All persons handling liquid gases are li-
able to acquaint themselves with the
special properties of the liquefied gases
for hazard-free handling of operations.
The current documentation is always to
be kept with the sweeper.
