The Reserve Air Supply System (RASS) is worn by NOAA Divers on their right side, as shown in the illustration below.
If a NOAA Diver wishes to use the RASS in a different configuration, a waiver request must be submitted through the diver's Unit Diving Supervisor to the Line or Staff Office Diving Officer.
- RASS cylinder valves are never to have a cap. The cap and string may interfere with opening the valve and/or removing the second stage from the bag.
- Don’t forget to remove RASS cylinders from the pouch to minimize cylinder oxidation. The bottom of the cylinders are especially prone to damage.
