(1) The strength of the deckhouses used for the
accommodation of the crew shall be to the satisfaction of the Administration.
(2) Efficient guard rails or bulwarks shall be
fitted on all exposed parts of the freeboard and superstructure decks.
The height of the bulwarks or guard rails shall be at least 1 metre
(39½ inches) from the deck, provided that where this height
would interfere with the normal operation of the ship, a lesser height
may be approved if the Administration is satisfied that adequate protection
is provided.
(3) The opening below the lowest course of the
guard rails shall not exceed 230 millimetres (9 inches). The other
courses shall be not more than 380 millimetres (15 inches) apart.
In the case of ships with rounded gunwales the guard rail supports
shall be placed on the flat of the deck.
(4) Satisfactory means (in the form of guard rails,
life lines, gangways or underdeck passages etc.) shall be provided
for the protection of the crew in getting to and from their quarters,
the machinery space and all other parts used in the necessary work
of the ship.
(5) Deck cargo carried on any ship shall be so
stowed that any opening which is in way of the cargo and which gives
access to and from the crew's quarters, the machinery space and all
other parts used in the necessary work of the ship, can be properly
closed and secured against the admission of water. Effective protection
for the crew in the form of guard rails or life lines shall be provided
above the deck cargo if there is no convenient passage on or below
the deck of the ship.
