Driving LPG is safe !!
LPG is a very safe fuel, whether it is to LPG or CNG. Serious accidents with LPG installations in cars have never occurred. Namely the government places high demands on LPG installations and companies that install them. A gas tank in the car is normally under a pressure of about 10 bar at an LPG plant and 200 bar with a CNG system.
In addition, each car gas system features an array of safety features. The gas flow, for example, automatically closed when the engine is switched off or dies accidentally. In order to prevent the pressure in the gas tank becomes too high, gas tanks are provided with a pressure relief valve, which in a LPG tank opens at 27 bar and 250 bar with CNG. In this manner is adjusted to the pressure tank in case of fire to safely allowable value. And on the right is a LPG tank provided with a filling plug 80% so that there is taken into account the possible expansion of the LPG at high temperatures and then has sufficient room to expand. Should the pressure in the gas tank car, for example, as a result of a fire nevertheless become too high, there occurs a pressure relief valve in operation, which immediately reduces the back pressure. In the event of a leakage the lekgas will always be carried away outside of the vehicle. ATTENTION to leaking, LPG is heavier than air and will therefore spread along the ground / soil, CNG is lighter than air and will therefore evaporates.
The LPG producers also add a fragrance to be sure to LPG, which is odorless naturally. One can thus smell the gas and become alerted if leaking refueling. All these safeguards, reduces the risk of accidents.
With regard to the safety of the LPG system components must comply with the European regulation R67. A CNG system shall comply with the regulations R110. This approval numbers must be present in all components so that they also can be verified.
