Should technicians be able to navigate what ever code is adopted at the state level and demonstrate proficiency in that code?
Of course they should! The statute specifies the code to be used and that is the State Fire Code that adopts NFPA 54 the National Fuel Gas Code. We should mention that this code is not new and is in full force and effect at this time. It currently requires that people in this trade be technically qualified. The lack of licensing does not negate your responsibility for installing and maintaining to the code. So it goes without saying that at some point you need to have a base knowledge of the code and demonstrate a level of proficiency in using it. No one expects you to know the code by memory that is why we have recommended an open book test.
