Proactive Action

Action organisation: Water Safety Service
Action number: MO-2011-007-NSA-004
Date: 05 April 2012
Action status: Closed

The company has advised the ATSB that it will place caution labels on all future oxygen cylinders.

These labels will draw attention to the fact that the re-filling and inspection of the cylinders must be carried out ashore; and that the cylinders should only ever be re-filled with oxygen.

   
Current issue status: Partially addressed
Status justification:

The company will place caution labels on all future OBA oxygen cylinders. These labels will draw attention to the fact that the re-filling and inspection of the cylinders must be carried out ashore; and that the cylinders should only ever be re-filled with oxygen. The company has taken actions to raise awareness but has not introduced any controls to prevent the inadvertent connection of an oxygen cylinder to an air system.
