Minnesota Boiler License Practice Exam

What grade license must the shift operator have where a chief engineer has charge of a plant of 500 boiler horsepower?

1. chief engineer

2. first class engineer

3. second class engineer

4. special engineers license

The correct answer is: second class engineer

In Minnesota, the licensing requirements for boiler operators are dictated by the horsepower rating of the boilers they will be operating. When a chief engineer is in charge of a plant with a total capacity of 500 boiler horsepower, the regulations specify the type of license required for other operators working under them. For a plant of this size, the shift operators must hold at least a second class engineer license. This level of certification indicates that the operator has received the necessary training and possesses a strong understanding of boiler operations, safety regulations, maintenance, and the management of potential hazards associated with running high-capacity boilers. The distinction in licensing levels helps ensure that operators have adequate knowledge and preparedness to manage the responsibilities involved, particularly in larger plants where the risks and technical operations are more complex. The requirement for a second-class license underscores the importance of having trained personnel capable of maintaining safe and efficient operations in environments handling significant boiler horsepower.
