The control panel on the ship should be installed in a convenient
                           location.
                        
                        
                        
                        
                        A plan of the ship's ro-ro cargo spaces, showing the location
                           of fans and openings, should be kept at the control panel. Each fan
                           should be given an individual designation.
                        
                        
                        
                        
                        Indications
                           as to which fans should be used for a given ro-ro cargo space under
                           various loading conditions should also be on display at the control
                           panel.
                        
                        
                        
                        
                        For safety reasons and to facilitate control of
                           the ventilation system, the control panel should include means of
                           indicating which fans are running.
                        
                        
                        
                        
                        The individual control
                           and indicator lights should be marked with the same designation as
                           the fans to which they relate.
                        
                        
                        
                        
                        As far as possible, indicator
                           lights and controls for fans that normally operate simultaneously
                           should be located in groups. This will help to make the function of
                           the controls readily apparent and will therefore facilitate correct
                           use of the controls.
                        
                        
                        
                        
                        Reference is made to the IMO Code
                           on Alarms and Indicators.
