G2 Gas Fitter Practice Exam

Are the provisions outlined in a B149 annex mandatory?

1. Always mandatory

2. Nomenclature only

3. Depends on the reference made to them in the base code

4. Not mandatory in any case

The correct answer is: Depends on the reference made to them in the base code

The stipulation that the provisions outlined in a B149 annex are mandatory is contingent upon the reference made to them in the base code. This means that while the annex may provide essential guidelines or recommendations, their enforceability is defined by how they are incorporated into the main code. If the base code explicitly states that certain annex provisions must be followed, then those provisions become mandatory. However, if the code merely references the annex without imposing compliance, then those provisions may not hold the same mandatory status. In essence, the applicability of the annex provisions largely hinges on the context provided in the base code. This flexibility allows for a tailored approach to gas fitting regulations, accommodating different situations while still providing comprehensive safety standards when required.
