11. TRANSPORTING COMPRESSED AIR CYLINDERS

Operator’s Manual
Compressed air as a pressurized gas mixture class 2, point 2a is subject to the dangerous goods motor regulations
(GGVS).
For the transportation of all dangerous goods one has to carry a transport sheet according to Rn. 2002 par. 3 of GGVS.
One can do without this, according to exception No. 55 of the dangerous goods regulation exceptions (GGAV), when the max. allowable
total gross quantity of each transportation unit according to Rn. 0011 does not exceed, with compressed air, 1000 kg ( equivalent
to approx. 70, 10 liter steel compressed air diving bottles).
In this case the compressed air cylinders are to be marked with the designation of the goods, the class, the point, and the letter of
the list of substances --in this case air, class 2 point 2a.
-- In every case the compressed air cylinders must be marked according to Rn. 2224 para. 1 with a danger label No. 2 (gas cylinder
black or white on green* background, small number ”2” in the bottom corner), see Fig. 33.
-- According to Rn 2203 para.1 gas containers -- including pressurized air -- must be closed and tight as to exclude any gas leakage.
-- The shut--off valves must be protected effectively, according to Rn.,2213 para. 2, with protecting caps. The protecting cap can
be done without of, if the compressed air cylinders are packed in protective boxes.
-- Compressed air cylinders must be, according to Rn. 21414, stowed in the vehicles in such a way that they cannot fall over or drop
off. Cylinders that are stable enough or those transported in the corresponding devices which protect them from falling over, can
be loaded upright. Horizontal bottles must be secured in such a way as to keep them from sliding.
-- According to Rn. 10011 of the enclosure B of the GGVS the regulations (e.g.: driver’s training, equipping of vehicles, caution
boards, accident bulletins) mentioned in Rn. 10011 do not have to be followed when transporting compressed air cylinders up
to a gross mass of 1000 kg per transport unit.
-- In general the following is valid with every transport of dangerous goods: During transportation smoking is forbidden, also during
loading within a parimeter of 10 meters.
-- Empty compressed air cylinders, in other words residual pressure below 2 bar are not subjectto the dangerous goods regulations.
