Some also perform other maintenance duties, such as carpentry, plumbing, and electrical repairs. Many work one of three daily 8-hour shifts, and weekend and holiday work often is required. Engine rooms, power plants 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.
Workers spend much of their time on their feet.
They may also have to crawl inside boilers and work in crouching or kneeling positions to inspect, clean or repair equipment. Because stationary engineers work around boilers as well as electrical and mechanical equipment, they must be alert to avoid burns, electric shock and injury from moving parts. They also must be aware of exposure to hazardous materials such as asbestos and certain chemicals. Computer skills are essential, because industrial systems are becoming increasingly computerized. In addition, a good background can be obtained in the Navy or the Merchant Marine because marine engineering plants are similar to many stationary power and heating plants.
