A project inspection procedure requires potential defects to be documented and referred for qualified assessment. An inspector finds visible corrosion on refrigerant piping. Which action follows that procedure?
- AOrder a complete replacement of the piping system
- Issue a notice of deficiency
- CPerform a visual inspection only
- DRequest a maintenance contract
Where to look it up
Explicit exercise assumptions; not a universal code requirement.
Why B is correct
Document the observed corrosion as a potential deficiency and refer it for assessment and required corrective action. The observation alone does not establish that the whole system must be replaced. Urgent hazards require appropriate immediate controls; this question does not prescribe an IFGC enforcement procedure.
