Narrative:

I recently traveled in a boeing 777. The safety video went through its animated instructions on seatbelts; life-jackets; oxygen; etc. It also informed on the ten 'emergency exits' and that 'doors 3' should not be used if the aircraft 'lands' on water. I was in seat xxc on the 'port side' next to one of the 3 doors. I only knew this because when the captain asked for the doors to be armed and crosschecked (if that is the phrase); the steward used the telephone to confirm that doors 3A and 3B had been 'set and checked.' which one is 'a' and which is 'b;' I do not know (and this is in fact irrelevant). However; there were no numbers on the doors at all and I would have expected in big red lettering: 'not to be used on water landing.' or words to that effect; on 'doors 3.' I asked the steward about this and explained that if he wasn't here; how many people would know? He was polite and assured me he would be there. The gentlemen in the seat next to me and the steward did concede at the time that I may have a point. The steward said he would pass on my remarks to the captain. The 'exit numbers' are shown on the flight safety card but I would suggest that most passengers (certainly those sitting in the centre four seats) have no idea where they are inside the cabin. With no numbers on the doors for reference; I believe this may cause confusion. Doors 3 are; as you will know; in the centre of the cabin and (I believe) a disproportionate percentage of passengers would see these doors as the closest to them; regardless of whether they should be used or not. On my return flight a few days ago the situation remains the same. I am only a layman in terms of flight safety and I am only making a suggestion. This observation does not reflect on the air carrier and their professionalism and I would be extremely happy to fly with them again; whether or not my suggestion is taken on board; to coin a phrase.callback conversation with reporter revealed the following information: reporter stated that since the incident of the airbus landing in the water; he started thinking about exit doors on aircraft. He realized after listening to the cabin safety video; he may not be able to tell which door he should not use; because none of them were marked.
