What equipment can a first-class engineer's license Grade B allow for operational responsibility?

Low-pressure boilers and their appurtenances
Low and high-pressure boilers
Total boiler horsepower not to exceed 50 horsepower liquid or vapor boilers and their appurtenances
Any boiler type regardless of horsepower

The correct answer is: Total boiler horsepower not to exceed 50 horsepower liquid or vapor boilers and their appurtenances

A first-class engineer's license Grade B specifically allows for operational responsibility that is limited to boilers with a total horsepower not exceeding 50. This includes both liquid and vapor boilers and their associated appurtenances. This restriction is designed to ensure that engineers operate within a defined scope that matches their level of training and experience, promoting safety and efficiency in boiler operations. This approach is consistent with regulatory standards aimed at ensuring that operators are properly qualified for the equipment they manage. Operating larger or more complex systems typically requires a higher level of expertise and certification, which is why broader options, such as low and high-pressure boilers or any type of boiler regardless of horsepower, would extend beyond what a Grade B license permits. Such limitations help protect operators, facilities, and the public from the risks associated with improperly managed boiler systems.
