With a current state of MN Chief Engineer's license (grade C), what boilers would you be allowed to operate?

Boilers of unlimited hp not to exceed 250 degrees F or 160 psi hot water and 15 psi steam
Boilers of unlimited hp and above 250 degrees F or 160 psi hot water and at 15 psi steam pressure
Boilers of unlimited hp above 15 psi but below 250 degrees F or 160 psi hot water
Boilers of 250 hp only at atmospheric pressure

The correct answer is: Boilers of unlimited hp not to exceed 250 degrees F or 160 psi hot water and 15 psi steam

A holder of a Minnesota Chief Engineer's license, Grade C, is authorized to operate certain types of boilers with specific limitations on temperature and pressure. The key aspect of this type of license allows operation of boilers of unlimited horsepower, but they must not exceed a temperature of 250 degrees Fahrenheit or a pressure of 160 psi for hot water boilers, and a maximum of 15 psi for steam boilers. This means that facilities which operate within these parameters can be managed by individuals holding this license, ensuring both safety and compliance with state regulations. The limitations help to ensure that engineers are handling systems that match their training and licensing level, promoting safe operation practices in accordance with the standards established by Minnesota regulations regarding boiler operation. The other options outline conditions that exceed the limitations defined for a Grade C license, such as higher temperature thresholds or pressures which are not permitted for this classification, thus confirming that the parameters of option A are consistent with the qualifications laid out for the license.
