Article 35 Storage of flammable liquids, toxic liquids, toxic gases and compressed gases

In every vessel of 12 metres in length and over to which these Rules apply cylinders containing flammable, toxic or other dangerous gases, and expended cylinders shall be properly stowed and secured on open decks, and all valves, pressure regulators and pipes leading from such cylinders shall be protected against damage. Such cylinders may be stowed in compartments which meet the requirements set out in paragraph (2) of this Rule.

In every such vessel highly flammable liquids, toxic liquids, toxic gases, and liquefied gases, other than liquefied petroleum gas shall be stored in compartments having direct access from open decks. Such compartments shall have boundary bulkheads constructed from non-combustible materials. Pressure adjusting devices and relief valves, if any, shall exhaust within the compartment. Where boundary bulkheads of such compartments adjoin other enclosed spaces they shall be gas tight and adequately insulated and provided with ventilation arrangements which are separate from other ventilation systems. Ventilation shall be arranged at high and low levels and the inlets and outlets of ventilators shall be positioned in safe areas and fitted with spark arresters.

In every such vessel electrical wiring and fittings shall not be installed within compartments containing highly flammable liquids or liquefied gases except where necessary for service within the space. Where such electrical fittings are installed they shall be suitable for use in a flammable atmosphere.

In every such vessel where cylinders containing flammable or other dangerous compressed gases are carried below deck, cylinders containing one type of compressed gas shall be stowed separately from cylinders containing another type. Compartments containing cylinders of such compressed gases shall not be used for stowage of other combustible products or for tools or objects not belonging to the gas distribution system.
