Minnesota Boiler License Practice Exam

In what size water or other liquid or steam or other vapor boiler may a special engineer serve as an apprentice?

1. In any plant regardless of the size, under direct supervision of the properly licensed engineer

2. Only in plants that do not exceed 300 bhp

3. 30 bhp high or low pressure

4. 200 bhp or more high or low pressure

The correct answer is: In any plant regardless of the size, under direct supervision of the properly licensed engineer

A special engineer may serve as an apprentice in any plant regardless of the size, as long as they are under the direct supervision of a properly licensed engineer. This provision allows apprentices to gain experience and training in a variety of boiler operations, which is essential for their development and competency in the field. Being able to operate within any size plant provides a broader exposure to different systems, processes, and operational practices. This real-world experience is invaluable for developing the skills and knowledge necessary to obtain a full license in the future. The requirement for direct supervision ensures a safety net for the apprentice, as they can learn in a controlled environment where a licensed engineer can provide guidance and intervention when necessary. The restrictions mentioned in the other options limit the range of experience an apprentice can gain, making it less effective for comprehensive training. By allowing apprentices to work in any plant size under supervision, the training becomes more versatile and applicable to the diverse situations they may encounter in their careers.
