What is the appropriate license for managing a boiler that is rated at 600 horsepower?

  1. First class engineer

  2. Second class engineer

  3. Chief engineer

  4. Special engineer's license

The correct answer is: Chief engineer

The appropriate license for managing a boiler rated at 600 horsepower is the Chief Engineer license. In Minnesota, the licensing system categorizes the authority to operate industrial equipment based on the size and horsepower of the boilers. A Chief Engineer license is required for high-capacity boilers, generally those that exceed certain horsepower thresholds, which include boilers rated at 600 horsepower. This designation indicates that the holder has attained the necessary training and expertise to manage such large and potentially complex systems safely and efficiently. The other license types, while also important in various contexts, do not cover the operation of large boilers. For example, the First Class Engineer license is typically designated for boilers of specific sizes, while the Second Class Engineer license and Special Engineer's license have even more limited scopes.
