PLEASE NOTE: This document only applies to Catalina Cylinders, new and used, SCUBA cylinders and in no way is meant to apply to the SCUBA cylinders manufactured by different entities.
Prior to June 2006, Catalina Cylinders SCUBA cylinders, as-manufactured, were not specifically cleaned for oxygen service and therefore are under no circumstances to be charged with oxygen enriched air, air containing oxygen concentrations in excess of 23.5%, unless the SCUBA cylinders have been specifically cleaned for oxygen service by trained personnel and labeled as such.
As of June 2006 all 3000psi service pressure, or less, Catalina Cylinders SCUBA cylinders, as-manufactured, have been specifically cleaned for oxygen service and therefore can be charged with oxygen enriched air immediately after purchase.
To charge a Catalina Cylinders SCUBA cylinder with oxygen enriched air, the following items must be verified before charging:
-
- The cylinder is currently clean as if for oxygen service. It should be a new 3000psi or less Catalina Cylinders SCUBA cylinder or a used Catalina Cylinders SCUBA cylinder that has a cleaned for oxygen service and a label affixed stating as such.
-
- All accessories and components which will come in contact with the oxygen enriched air charge have been manufactured cleaned for oxygen service or have been cleaned and certified as clean for oxygen service by properly trained personnel.
-
- All lubricants used on Catalina Cylinders SCUBA cylinders, all accessories and components which come in contact with the oxygen enriched air charge are compatible with high pressure oxygen usage and aluminum.
-
- The o-rings and other non-metallic materials which come in contact with the oxygen enriched air charge are compatible with high pressure oxygen usage.
- All other items and materials that may come in contact with oxygen enriched air during the charging, use and/or storage of the Catalina Cylinders SCUBA cylinder and its components and accessories which have been cleaned for oxygen service, have been cleaned for oxygen service.
Warnings
-
- Failure to verify the above items have been addressed before charging a SCUBA cylinder with oxygen enriched air may lead to a catastrophic event that can cause property damage, serious injury or even death.
- The U.S DOT has interpreted its regulations stating that DOT-3AL (aluminum) SCUBA cannot be charged with oxygen enriched air to a service pressure greater than 3000psi. Thus, Catalina Cylinders 3300psi compact SCUBA cylinders cannot be charged with oxygen enriched air as mandated by the DOT. For more information on this matter please contact Catalina Cylinders.
