Cargo tank vent outlets are not to be closer than 15m to inlets to the accommodation. In general these cargos are unsuitable for carriage in mild steel tanks (generally acids and petrochemical substances) B Low flash point e.g. Carbon tetrachloride Toxic Skin hazard Formaldehyde Benzene Are not as restrictive as the type A although they are toxic and many have a low flash point their problems with relation to water are not as great. Mild steel is suitable for tanks but aluminium and copper are not. C Low flash point acetone Asphalt Caustic soda Are less dangerous and most are not toxic in general. Most engineering materials are suitable for tank construction. There is some risk of contamination through water but it is not great 2
