Problem with laird water chiller/heat exchanger which cools the fluoroscopy machine in the hospital's interventional radiology (ir) dept.The water chiller's capacitator failed causing a fire.Patient was not in room at time of fire.Equipment had been turned on in preparation for procedure, but fluoroscopy machine was not yet in use on patient.Staff walking by the room heard loud cracking/popping noises in the equipment cooling room.Staff then noted flames shooting out of the water chiller.Smoke caused fire alarm activation.Fire was contained and extinguished itself after equipment was turned off.Overheating error alarm had occurred one month prior; biomed serviced the chiller and added water to it.Biomed did not note any leak in the system; however, there were towels noted on the floor in the equipment room suggesting the machine may have been leaking fluid.Ir staff reported the machine had been "running hot" that week.After the fire, the chiller was drained, noting only 1l of fluid.Chiller normally contains 4l.Suggestive of possible leak.However, biomed opined that capacitator failure/defect caused the device to overheat, causing the fire.
