DANGEROUS MATERIAL CODES
Today more than one million chemicals are carried with sea transport. The difficulties of knowing so many ,with one by one different materials , acting accordingly is obvious. As a result of this difficulty, on 1960  Known as IMCO International Maritime Consultative Organization , the most important dangerous chemicals, has been gathered with classifying under short name IMDG - C (International Maritime Dangerous Goods - Code) .
