The following bulletin was issued by NGVAmerica and the Clean Vehicle Education Foundation(CVEF). Though aimed at the US market, the safety message is relevant to most other markets as well.
As gasoline and diesel prices continue to rise, many people are considering converting their car or light truck to run on compressed natural gas (CNG). CNG is a clean, inexpensive (currently selling for less than half the cost of gasoline) domestic fuel. Best of all, it uses zero imported (or domestic) petroleum. And government rebates are available to help with the cost of conversion and to further lower the cost of CNG fuel. But conversion from gasoline to CNG should not be done by unqualified technicians, using unapproved conversion kits or unsafe high-pressure gas cylinders.
The US Environmental Protection Agency (EPA) has rules concerning the manufacture, sale and installation of alternative fuel engine conversion systems. The California Air Resources Board has similar and even more stringent emission rules for conversions in that state. Only EPA and/or CARB-certified conversion systems are permitted to be installed on vehicles. While a variety of non-certified systems are sold on the Internet and/or offered by some automotive shops, EPA has taken the position that installation of these systems is "tampering with a federally approved emission control system", a federal violation punishable by a substantial financial penalty. Installation of non-certified systems can also cause a vehicle to fail emissions inspection.
