In Alberta, which boilers are Power Engineers required to operate?

In Alberta, the regulations governing the operation of boilers specify that Power Engineers must have the appropriate credentials to operate certain types of boilers based on their size and classifications outlined in the Alberta Safety Codes Act. The correct response indicates that Power Engineers are required to operate Section I boilers over a capacity of 20 kW and Section IV boilers that exceed 750 kW.

Section I boilers generally include water tube and high-pressure steam boilers, which are typically used in applications requiring high steam pressures and have a large capacity. Therefore, certification to operate these boilers is necessary due to the safety considerations associated with their operation. These boilers tend to be more complex in design and operation compared to some other classes.

Section IV boilers, which often include lower-pressure steam heating systems, also have specified thresholds where the expertise of a Power Engineer becomes necessary. A rating above 750 kW denotes larger installations, which further justifies the need for professional oversight to ensure safe operation.

The other choices do not align with the regulatory requirements as they either include boilers of sizes that do not necessitate the same level of operational training or overlook important size thresholds that categorize boilers requiring licensed Power Engineers. Thus, the selected response accurately reflects the requisite knowledge and capabilities for Power Engineers within Alberta's boiler operation
