6.2 Documentation

 An operation manual should be supplied based on these operational recommendations and should include a plan of the ventilation system, showing fans, supply air and exhaust air openings and doors, ramps, hatches, etc. The location of the control panel for the ro-ro cargo space ventilation system should also be marked.

The plan should show the various options for operation of the ventilation system. It should include details of the design air flow and of the estimated number of different types of vehicles in the different ro-ro cargo spaces under various loading and unloading conditions.

The plan should be periodically revised and/or supplemented on the basis of the experience gained from the normal vehicle loading and unloading conditions. A number of blank drawings should therefore be kept on board.

On the basis of such experience, it should also be possible to draw up guidelines for the maximum number of vehicles that should be allowed to operate simultaneously.

The air flow should be indicated in colour on the plan in accordance with the following recommended standard taken from ISO 5571, Identification Colours for Schemes for Ventilation Systems:

  Supply air, natural ventilation - Yellow
  Exhaust air, natural ventilation - Brown
  Supply air, mechanical ventilation - Green
  Exhaust air, mechanical ventilation - Grey

 The operation manual should include guidance for the service and maintenance of the systems.
