MERCHANT SHIPPING (SEAFARERS) (CREW ACCOMMODATION) REGULATION - SECT 12

Pipes, etc.

(1) Except where no other arrangement is reasonably practicable, steam supply
and exhaust pipes for steering gear, winches and similar equipment shall not
pass through the crew accommodation. Where any such pipes do pass through the
crew accommodation they shall pass through passageways only, shall be properly
encased, and in the case of supply pipes-

   (a)  shall be constructed of solid drawn steel or other suitable material;

   (b)  shall be of a scantling sufficient to withstand the maximum pressure
        from the ship's boiler system;

   (c)  shall have all connections made by faced flanges properly jointed; and

   (d)  shall be fitted with adequate drainage arrangements.

(2) Steam pipes, hot water pipes and calorifiers in the crew accommodation
shall be efficiently lagged wherever necessary for the protection of the crew
against injury or discomfort. Cold water pipes in the crew accommodation shall
be lagged where necessary for the prevention of condensation.

(3) Where any parts of chain pipes and ventilator trunks to cargo spaces or
tanks pass through the crew accommodation, they shall be made of steel or
other suitable material and be gastight.

(4) Pipes used for crew accommodation services shall be of adequate dimensions
having regard to their particular purpose and, in addition, soil pipes and
waste pipes shall be so constructed as to minimize the risk of obstruction and
to facilitate cleaning.

(5) Soil pipes shall not pass overhead in mess rooms, sleeping rooms, dry
provision store rooms, galleys or the hospital, except where it is
impracticable to place them elsewhere.

(6) No soil pipe or waste pipe shall pass through drinking water tanks or
other fresh water tanks.

(7) Hawse pipes shall not pass through the crew accommodation. (Enacted 1995)
