Medical device manufacturer, Philips Healthcare, has issued a field safety notice concerning Uninterruptable Power Supply (UPS) batteries used with Philips computed tomography and molecular imaging systems.
The manufacturer has become aware of UPS device failures that resulted in leaking of electrolyte (sulfuric acid), overheating and/or emission of fumes. Analysis has identified that these failures are most likely due to batteries within the UPS devices being held in service beyond their usable service life – typically three to five years.
Hazards involved as a result of UPS devices failing include chemical burn, thermal burn and eye, nose and/or throat irritation.
The manufacturer advises users to review the accompanying material and implement a UPS maintenance programme at their facility as recommended by the manufacturer of their UPS. To ensure continued safe and reliable performance from these devices, periodic maintenance is required - including possible battery replacement.
The manufacturer has provided a UPS information flyer outlining maintenance needs and a suggested maintenance strategy.
According to Philips Healthcare, the concerned UPS batteries are distributed in Hong Kong.
If you are in possession of the affected products, please contact your supplier for necessary actions.
