The work involves responsibility for supervising the operation of a Boiler Power Plant involving the safe and efficient operation of automatic high or low-pressure boilers to produce steam, hot water and heat to one or more large buildings. The boilers may be either fire tube or water tube design, powered by either fuel oil or gas; and internal pressures of the boilers may vary in range. The Power Plant Supervisors may also plan, layout and supervise plumbing and steamfitting work for the facility. Work is periodically reviewed by a higher level employee through observation and/or inspection of the power house operation and work performed by power plant staff. Supervision is exercised over a number of Boiler Operators and Boiler Operator Maintenance Workers.
