Robertshaw Controls Company is attempting to locate approximately 900 demand-type resuscitators which may fail if damaged or improperly reassembled.
The company said the Model 4201 demand valve resuscitator is commonly used in ambulances, dispensaries and other emergency life support areas to provide emergency oxygen.
Robertshaw said damage to the valve could cause failure of a rubber diaphragm in the pressure regulating mechanism which could result in a dangerously excessive oxygen supply pressure being administered to a patient. The units sought are of an early design.
Owners of Robertshaw Model 3201 demand valve resuscitators, serial numbers 0001 through 1800, should remove those units from service and contact Robertshaw Controls Company at 714-535-8151.
Units with serial numbers above 1800 are not involved, but should be tested periodically as recommended in the manufacturer’s operating instructions.
