Parent topic: Chapter 6 Environmental Conditions

3.1 General

3.1.1 Ergonomic factors, consideration should be made for work in all parts of the dive system which does not involve just seated or standing operation at a workstation. Reference should be made to ISO 6385.

3.1.2 The working positions of the crew and the comfort of passengers are to be considered in order to maintain the maximum efficiency when working, assuming personnel of approximately average height and length of reach for the controls. Furniture such as seats, bunks, tables, lockers, etc., should be provided as appropriate. Figure 6.3.1 Console for operation sitting or standing is provided for guidance.

3.1.3 Where practicable, adjustable equipment should be considered to permit optimum use by personnel differing significantly in size.

3.1.4 The positioning of instruments, the shape and colour of switches and push buttons should be specially considered to minimize human error in operation, especially in the event of a lighting failure.

3.1.5 Manned submersibles should be provided with sufficient illumination in all areas to ensure efficient operation. Secondary illumination should be provided from a separate power source in living spaces, the secondary illumination should have a minimum level of 50 lx, and the normal average about 370 lx. Coloured lighting may be used as considered necessary. Reference is to be made to ISO 8995 or equivalent for illumination levels.
