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. The increasing complexity of the equipment with which they work has made a high school diploma or its equivalent necessary.
Many stationary engineers have some college education.
Apprenticeship programs are sponsored by the International Union of Operating Engineers, the principal union to which stationary engineers belong. An apprenticeship usually lasts 4 years. Those who acquire their skills on the job usually start as helpers to experienced stationary engineers or as boiler tenders. This practical experience may be supplemented by postsecondary vocational training in computerized controls and instrumentation. However, becoming a stationary engineer without completing a formal apprenticeship program usually requires many years of work experience.
