Minnesota Boiler License Practice Exam

A special engineer may serve as an apprentice in what size maximum vapor boiler plant?

1. 100 hp high or low pressure plant

2. In any plant under direct supervision of the properly licensed engineer

3. 50 horsepower high or low pressure plant

4. All plants regardless of size

The correct answer is: 100 hp high or low pressure plant

A special engineer is typically limited in their operational scope depending on the specific regulations governing engineers' licenses. In the context of Minnesota's rules, the maximum size limit for a vapor boiler plant where a special engineer may serve as an apprentice is clearly defined as 100 horsepower for both high and low pressure plants. This regulatory framework is designed to ensure that special engineers gain sufficient experience and training while still being overseen by someone who holds the appropriate licensure. While it may seem conceivable that they could operate in any size plant under supervision, the regulations are specifically constructed to maintain safety standards and operational integrity. The limitation to 100 hp serves to balance the need for apprentices to gain hands-on experience with the necessity of ensuring that they are not left in control of larger systems that could pose more significant risks without the requisite knowledge and skill level developed through extensive training. Therefore, the correct answer highlights the regulatory parameter that oversees the apprentice’s involvement in such boiler plant operations, ensuring they work within a framework that prioritizes both legal compliance and safety.
