The Marion Veterans Affairs Medical Center (VAMC) has a central boiler plant to provide steam for heating and air conditioning, domestic hot water, kitchens, and sterilization. Boiler plant safety, reliability, efficiency, and equipment longevity are paramount concerns of VAMC management. Boilers are extremely dangerous if not maintained properly. Malfunctioning burners or controls can cause catastrophic events resulting in injuries and death as well as massive property damage. Inaccurate or inadequate data management and monitoring systems can fail to warn of unsafe or inefficient performance. Regular inspections, testing and calibration by expert technicians are an essential part of a program to address these concerns. Veterans’ Health Administration (VHA), Directive 1810 requires annual and/or semi-annual Boiler and associated plant equipment inspection, safety device testing, calibration, and combustion tuning. VHA Directive 1810 requires these services to be performed by a qualified professional third party that has documented knowledge and experience in the design and construction and VA’s standards for construction and testing of safety devices. In addition, the individual shall have demonstrated experience in conducting equipment assessments and performing testing in compliance with the VA safety device testing manual.
