Stationary engineers and boiler operators typically do the following:
Most large commercial facilities have extensive heating, ventilation, and air-conditioning systems that maintain comfortable temperatures all year long. Industrial plants often have additional facilities to provide electrical power, steam, or other services. Stationary engineers and boiler operators control and maintain boilers, air-conditioning and refrigeration equipment, turbines, generators, pumps, and compressors.
Stationary engineers and boiler operators start up, regulate, repair, and shut down equipment. They monitor meters, gauges, and computerized controls to ensure that equipment operates safely and within established limits. They use sophisticated electrical and electronic test equipment to service, troubleshoot, repair, and monitor heating, cooling, and ventilation systems.
Stationary engineers and boiler operators also perform routine maintenance. They may completely overhaul or replace defective valves, gaskets, or bearings. In addition, they lubricate moving parts, replace filters, and remove soot and corrosion that can make a boiler less efficient.
Stationary engineers and boiler operators need at least a high school diploma. Students should take courses in math, science, and mechanical and technical subjects.
With the growing complexity of the work, vocational school or college courses may benefit workers trying to advance in the occupation.
Some state and local governments require licensure for stationary engineers and boiler operators. These governments typically have several classes of stationary engineer and boiler operator licenses. Each class specifies the type and size of equipment the engineer is permitted to operate without supervision. Many employers require stationary engineers and boiler operators to demonstrate competency through licenses or company-specific exams before they are allowed to operate the equipment without supervision.
A top-level engineer or operator is qualified to run a large facility, supervise others, and operate equipment of all types and capacities. Engineers and operators with licenses below this level are limited in the types or capacities of equipment they may operate without supervision.
Applicants for licensure usually must meet experience requirements and pass a written exam. In some cases, employers may require that workers be licensed before starting the job. A stationary engineer or boiler operator who moves from one state or city to another may have to pass an examination for a new license because of regional differences in licensing requirements.
