  I read that article and another article about EEBDs [1], and one thing wasn't quite clear to me. Unless I'm really misunderstanding what I read, it sounds as if there could be fewer EEBDs than there are people who might need them in an emergency. In the section on passenger ships, it says "Where the ship carries more than 36 passengers there must be four EEBD’s in each main fire zone within the accommodation spaces." What if there are more than 4 passengers in a fire zone?

    The EEBDs are not primarily for the passengers. If there's a fire passengers should be evacuated. Unless the vessel is likely to sink or capsize imminently the safest place for the passengers is probably on deck. For serious fires the passengers will probably self-evacuate, humans are scared of fire. Correct operation of the EEBD requires training, the intent is that your fire response teams can use EEBDs to keep themselves safe while entering spaces without breathable air, particularly if using CO2 extinguishers (very common in machinery spaces on ships).
