A holder of a Certificate of Competency may operate, repair, and advise on all things pertaining to which type of facility?

The correct answer is that a holder of a Certificate of Competency may operate, repair, and advise on all things pertaining to a power plant. This certification specifically equips individuals with the necessary knowledge and skills to handle various equipment and systems within a power generation facility. Power plants involve complex machinery, including boilers, turbines, and auxiliary systems, all of which require a solid understanding of thermodynamics, fluid dynamics, and safety protocols.

In contrast, places like a welding shop, an automotive shop, and a fish plant primarily focus on different trades that do not fall under the jurisdiction or expertise covered by a Certificate of Competency in power engineering. The training for a power engineer includes specialized topics such as steam generation, electrical systems, and compliance with safety regulations specific to the power industry, which are not applicable in those other facilities.
