Pacific Consolidated Industries, LLC, and FDA notified healthcare professionals of the Class I Recall of the Mobile Oxygen Storage Tank manufactured and distributed between January - March 2007, because the device's pressure gauge may rupture and may catch fire as a result of hydraulic fluid present in the pressure gauge tubing. The mobile oxygen storage tank is used in military aircraft for treating wounded patients and in disaster areas to quickly supply oxygen to patients. Facilities with the Mobile Oxygen Storage Tank should keep the device in quarantine until arrangements are made to ship the device back to the manufacturer.
