A Vehicle Conversion (CNG/LPG – Compressed Natural Gas / Liquefied Petroleum Gas) certificate of qualification is awarded to an individual who has successfully received a Certification of Qualification for both Vehicle Conversion (CNG) and Vehicle Conversion (LPG) offered by Technical Safety BC.

The scope of work of certification without endorsement(s) is limited to service, inspection and maintenance only. Installation and or alteration of approved vehicle fuel systems requires an additional endorsement specific to the applicable manufacturer’s fuel system. Approved training must be acquired on specific system(s) and an appropriate record of successful completion provided to Technical Safety BC. The endorsement will then be attached to the individual’s certification. In some cases, multiple endorsements may be required.

This Certification does not entitle the holder to work on CNG related systems as part of an LNG equipped vehicle. An LNG endorsement must be acquired for this purpose and attached to the certification.
