moved. Valves should be closed when the cylinder is empty.
Cylinder valves controls and associated fittings should be kept free from oil, grease and paint. Controls should not be operated with oily hands.
Gas cylinders should be clearly marked with the name of the gas, its chemical formula or symbol and the body should be coloured according to its contents. AS/NZS 4484-/NZS-2004 Gas cylinders for industrial, scientific, medical and refrigerant use – Labelling and colour coding or its equivalent, sets out the requirements for the labelling of gas cylinders. A colour-coding card should be provided.

   9.      Welding, flame cutting and other hot work
Risks associated with welding, flame-cutting and other hot work must be controlled using the permit-to-work system and in accordance with the ship's safety management system.
General guidance on how to manage risks associated with welding is available in Safe Work Australia's Code of Practice Welding processes.
The operator must provide appropriate training, information and instructions to seafarers that will be required to operate welding and flame-cutting equipment.
The equipment should be inspected before use by a competent person to ensure that it is in a serviceable condition.
Harmful fumes can be produced during these operations from galvanising paint and other protective materials. Oxygen in the atmosphere can be depleted during these operations. Adequate ventilation should be provided during flame cutting and welding operations in confined spaces (refer to section 7). Compressed gas cylinders must not be brought into confined spaces.
Where portable lights are needed to provide adequate illumination, they should be clamped or otherwise secured in position with leads kept clear of the working area.
The equipment operator and other persons involved in the work process should wear appropriate PPE, for example:
       a welding shield or welding goggles with a suitable shade of filter lens (goggles are only recommended for gas welding and flame cutting);
       leather gloves;
       fire resistant apron (e.g. leather) when appropriate; and
       long-sleeved natural-fibre boiler or other approved protective clothing.

9.1              Precautions against fire and explosions
Before any work begins, inspections and tests should be carried out to ensure there are no combustible solids, liquids or gases at, or in any compartments adjacent to, the work area which might be ignited by heat or sparks from the work. An assessment of the task in the context of other work being done on board should be undertaken by a responsible officer.
All surfaces to be welded, or upon which hot work is to be conducted, should be free of oil, grease or any flammable or combustible materials. If necessary, combustible materials and dunnage should be moved to a safe distance before commencing hot work. Such working surfaces should also be
