Formaldehyde
From Cargo Handbook - the world's largest cargo transport guidelines website
Shipped in drums, barrels, bottles or carboys and used in the manufacture of fertilisers, dyes, disinfectants and germicides.
Usually sold and transported as a 40% aqueous solution, and under certain circumstances may become a white solid.
If carried in kegs or barrels there is usually a loss in weight and corrosion of the fastenings if these are of metal.
May develop acidity; this causes considerable depreciation and is usually due to the presence of inherent impurities.
If packed in a freight container, on unpacking, time should be allowed for dispersal of any fumes, before entering container.
Moderate fire risk. Toxic by inhalation. Strong irritant carcinogenic (solution).
Hazard: IMDG Class 3.3 Flammable liquid.
