Gas vehicles
Leakage
WARNING!
Remove all ignition sources in the vicinity of a gas leakage during
evacuation.
WARNING!
The gas can cause suffocation in confined spaces.
WARNING!
Liquid vehicle gas, LNG, is extremely cold. Leakages can lead to personal
injury.
If a high-frequency high whining noise is heard, this indicates that the gas
system has a leak.
Gas leakage from CNG pressurised vehicle gas can also be identified by an
acrid odour if the gas has had an odour added.
Major LNG liquid vehicle gas leakages can be seen as a mist since the cold gas
makes the water in the air condense.
If a gas leakage has been identified, evacuate the area until no sound can be
heard, no mist can be seen and no odour detected.
Pressurised vehicle gas, CNG, is lighter than air and therefore rises in the event
of leakage. Take this into account if leakages occur, for example indoors or in a
tunnel.
Liquid vehicle gas, LNG, is initially heavier than air because it is cooled. It
rises as the temperature increases.
