2.1 LPG cylinders, regulators and safety devices
should be stowed on the open deck (where leakage will not accumulate)
or in a compartment that is vapour-tight to the vessels interior and
fitted with a vent and drain, so that gas which may leak can disperse
overboard.
2.2 The vent and drain should not be less than
19 mm in diameter, run to the outside of the craft and terminate 75
mm or more above the 'at rest' waterline. The drain and locker ventilation
should be 500 mm or more from any opening to the vessels interior.
2.3 The cylinders and associated fittings should
be positively secured against movement and protected from damage in
any foreseeable event.
2.4 Any electrical equipment located in cylinder
lockers should be certified safe for use in the potential explosive
atmosphere.
