Primary duties: Gas plant operators oversee the storage, production and transport of different types of gas. They control and monitor compressors, pipelines and distribution tanks to keep gases at pressurization and temperature levels. Most gas plant operators work for oil and utility companies where they check gauges and maintain equipment as necessary.
Requirements: To start a career in plant operations, candidates must have at least a high school diploma or equivalent. Also, due to the dangerous nature of the job, employers usually require candidates to complete technical training programs and pass extensive licensing examinations. In the U.S., most states require new gas plant operators to pass licensing examinations that test their knowledge of various terminologies, legal and safety issues and basic procedures.
