G2 Gas Fitter Practice Exam

Is a holder of a valid G.2 certificate allowed to work on a propane powered highway vehicle's carburation system?

1. Yes, they are fully certified for such work

2. No, they are not certified to work on that system

3. Only if they have additional training

4. Yes, but only under supervision

The correct answer is: No, they are not certified to work on that system

A holder of a valid G.2 certificate is not certified to work on a propane-powered highway vehicle's carburation system due to specific regulatory limitations surrounding the scope of their certification. The G.2 designation typically focuses on residential and commercial gas fitting, including appliances and connections but does not extend to the intricacies involved in vehicular systems. Working on vehicle carburation systems usually requires specialized knowledge and certifications that are geared towards automotive systems and propane use in that context. This specialization is essential due to the unique challenges and safety considerations associated with vehicle operations, which differ significantly from those encountered in stationary gas installations. As such, individuals with a G.2 gas fitter certification must refrain from engaging in work on propane-powered vehicle carburation systems unless they possess the additional qualifications or certifications specifically tailored for that area. This ensures that all work done adheres to safety regulations and best practices, protecting both the worker and the public.
