For the separator spaces

For the separator spaces under E.10.1 and E.10.2 a specific capacity rate of 30 air changes
per hour is deemed to be sufficient. Higher air rates may be required due to heat generation within the
space.
E.11 Emergency generator rooms
E.11.1 The ventilation system serving the emergency generator room has to ensure a sufficient supply
of combustion and cooling air for the equipment installed.
E.11.2 In general, ventilators necessary to immediately supply the emergency generator room must
have coamings which comply with regulation 19(3) of LLC 1966, without weathertight closing appliances,
see also D.3.2. However, where due to vessels size and arrangement this is not practicable, lesser
heights for emergency generator room ventilator coamings may be accepted. In this case weathertight
closing appliances in accordance with regulation 19(4) of LLC 1966 in combination with other suitable
arrangements have to be provided to ensure an uninterrupted, adequate supply of ventilation to these
spaces 5.
E.11.3 Bulkheads between emergency generator room and open decks may have air intake openings
without means of closure, unless a fixed gas fire fighting system is fitted. However, for passenger vessels
carrying more than 36 passengers the ventilation openings are to be fitted with fire closures, which are to
be capable of being closed from outside the emergency generator room
