Carbon dioxide systems
Carbon dioxide systems are to comply with 7.1 in addition to the remaining requirements of this sub-Section.
For the purpose of this Chapter, the volume of free carbon dioxide is to be calculated at 0,56 m3/kg.
For machinery spaces:
- The quantity of carbon dioxide carried is to be sufficient to give a minimum volume of free gas equal to the larger of:30 per cent of the gross volume of the largest machinery space protected, including the casing;
- The fixed piping system is to be such that 85 per cent of the gas can be discharged into the space within two minutes; and
- The distribution arrangements are to be such that approximately 15 per cent of the required quantity of carbon dioxide is led to the bilge areas.
