Stationary engineers also perform routine maintenance, such as lubricating moving parts, replacing filters, and removing soot and corrosion that can reduce operating efficiency. They also may test boiler water and add chemicals to prevent corrosion and harmful deposits. In a large building or industrial plant, a stationary engineer may be in charge of all mechanical systems in the building or an industrial powerplant or engine room. Engineers may direct the work of assistant stationary engineers, turbine operators, boiler tenders, and air-conditioning and refrigeration operators and mechanics. In a small building or industrial plant, there may be only one stationary engineer at any time.
Stationary engineers operate equipment which provide power to buildings.
Working Conditions Stationary engineers generally have steady year-round employment. Many work one of three daily 8-hour shifts, and weekend and holiday work often is required. Engine rooms, powerplants, and boiler rooms usually are clean and well lighted. Even under the most favorable conditions, however, some stationary engineers are exposed to high temperatures, dust, dirt, and high noise levels from the equipment. General maintenance duties may cause contact with oil and grease, as well as fumes or smoke.
