Separating partial bulkheads of spaces
If a space is divided by partial bulkheads into two (or
more) smaller areas such that they form enclosed spaces, then the
enclosed spaces should be surrounded by bulkheads and decks in accordance
with tables7.4-1 and 7.4-2, as applicable. However, if the separating
bulkheads of such spaces are at least 30 % open, then the spaces may
be considered as the same space.
Cabinets having a deck area of less than 2 m2 may
be accepted as part of the space they serve provided they have open
ventilation to the space and do not contain any material or equipment
which could be a fire risk.
