Safety Aspects of CNG Cars

The results of a study of major safety aspects of the use of natural gas as fuel for automobiles are presented. First the risks involved in the parking of CNG automobiles (Compressed Natural Gas) in underground parking lots are identified and a comparison is made with the risks connected with gasoline and LPG driven cars. In the second part of the paper the risks of a so-called “slow fill” compression device with which a CNG tank can be filled at home is analyzed.
