Specifically, the decision on the 200 bar oxygen cylinders follows the regulations implemented in an increasing number of countries that eliminate the filling pressure of medical oxygen to below the 200-bar recommended in the Medical First Aid Guide (MFAG).

Thus, RMI recommends that all vessels, despite their size and type, that carry substances, material, or articles identified in the IMDG Code as marine pollutants are subject to the provisions of this Code.

 

 

RMI states that medical oxygen cylinders with less than a 200-bar filling pressure may be used provided that the total volume of oxygen delivered by multiple cylinders is at least equal to that contained in a 40 liter/200 bar cylinder or a 2 liter/200 bar cylinder.

The above can be achieved by supplying more cylinders. Yet, stakeholders should be advised by a manufacturer before using the cylinders onboard, to be informed about the correct volume.

The Marshall Islands recommend that:

  1. the filling pressure for all cylinders must be the same;
  2. the cylinders must be stored in a fixed position to prevent movements during bad weather conditions;
  3. the cylinders must be fitted with a pressure regulating unit and pressure gauge, with one extra key to open the cylinder; and
  4. all cylinders must have the same connectors and color.

The entire system must be inspected annually by a competent person in accordance with manufacturer’s instructions.
