FATTY ACIDS - Subject to a natural loss in weight. If shipped to hot climates in metal drums a clearance of or 4 inches should be left between the surface of the arid and lid of the drum to allow for expansion.
Pressure from the acid, combined with corrosive effect, may hole or burst the drums in very hot weather.
Fatty acids should be packed in suitable drums allowing for contraction and expansion due to temperature change.
Distilled fatty acids, when coming into contact with a metal such as iron, cause a corrosion which will affect the color. This is a process of oxidation which can be controlled both chemically and physically. Ships tanks carrying such commodities should be submitted to a special treatment, e.g. coated with insulating material. See also IMDG Code & US CFR.
