A pressure vessel or boiler inspector inspects pressurized systems. Their duties include reading gauges to ensure the equipment is running at the proper pressure, checking the vessel for any signs of wear or damage, and making minor repairs as necessary. The responsibilities of a boiler inspector also involve the maintenance of safety devices that monitor pressure continuously. Qualifications for this career vary but may include a bachelor’s degree in engineering. Depending on the type of system, technical training and professional certification may be sufficient.
