Large buildings and industrial facilities — hospitals, universities, high-rises,\nfactories — depend on central plants that produce and distribute heat, cooling,\nsteam, compressed air, and power, and on the boilers and pressure vessels at their\nheart, which store enough energy to level a building if they fail. Stationary\nengineering exists to operate and maintain that machinery safely and efficiently:\nrunning the boilers, chillers, pumps, and HVAC systems that keep a facility\nfunctioning, and above all keeping the high-pressure equipment from the catastrophic\nfailure it's capable of. The stationary (or operating) engineer is the licensed\nprofessional who runs the building's central plant — the reason the hospital has\nheat, the high-rise has air conditioning, and the boiler that could explode never\ndoes. Without them, the facility's environment fails and its pressure equipment\nbecomes a hazard.

They report to facilities managers (who own the\nbuilding operation and budget) and coordinate with boiler inspectors and regulators\n(who certify the pressure equipment's safety), water-treatment vendors, and the\noccupants whose comfort and critical operations (e.g. hospital sterilization,\nresearch) the plant serves. The defining relationships are the shift turnover\n(continuity of safe operation) and the boiler-inspection regime (independent\nverification of the equipment that could explode). In critical facilities, the\nengineer's reliability directly enables operations that can't lose heat, steam, or\ncooling.
