Bilge overboard valves should be suitably marked. Specific warning notices should be posted to safeguard against the accidental opening of bilge overboard discharge valves. Valves should be lashed and sealed.Regrettably some vessel crews were interpreting this guidance to imply that chains or fixed iron bars should be used to make the opening of such valves impossible. This was of course not the intention of the guidance, however IMCA recognises that such an important issue must be addressed swiftly. Hence the guidance has been adjusted to read as follows:
Emergency bilge suction valves should be suitably marked and specific warning notices posted to safeguard against the accidental opening. They can also be fitted with a visible tag which does not prevent the operation of the valve.Any further information on this or any other aspect of the eCMID can be addressed to IMCA, for attention of Chris Baldwin.
