Product Code:SAE AIR1059
Title:Transfilling and Maintenance of Oxygen Cylinders
Issuing Committee:A-10 Aircraft Oxygen Equipment Committee
Scope: Recharging of small portable oxygen cylinders by the user is a practice both condemned and discouraged by the Compressed Gas Association (CGA) and the National Fire Protection Association (NFPA). Their condemnation is based on the firm conviction of the majority of the Association members that 'transfilling' and oxygen cylinder by 'unqualified' personnel is basically unsafe and should not be performed. By logic, therefore, it must be deduced that all personnel assigned to transfilling must be qualified. The purpose of this document is to list the best available information and guidelines for the qualification of personnel who are responsible for the filling of fixed or portable aircraft oxygen cylinders. It is a matter of record that the commercial airlines, aircraft manufacturers, and aircraft service stations have been involved in, and will continue to follow, the practice of filling the small portable oxygen units and fixed oxygen cylinders in commercial and general aviation. This practice has developed over the last twenty years and, while there have been occasional accidents, the practice will not be stopped. The lost time, paper work, cost, etc., involved in sending cylinders to a commercial gas supplier is economically unsound. As this is the case, it logically follows that a standardized procedure should be established for charging high pressure oxygen cylinders in those aviation facilities which are required by circumstances to perform oxygen cylinder filling.
