Classes of hazard of freight
class 1 - explosive materials (EM);
class 2 – compressed, liquefied gases and gases dissolved under pressure;
class 3 - inflammable liquids (IL);
class 4 - inflammable solids (IS), self-igniting substances (SS), substances, extracting inflammable gases during interaction with water;
class 5 - oxidizing agents (OA) and organic peroxides (OP);
class 6 - poisonous substances (PS) and infectious agents (IA);
class 7 - radioactive materials (RM);
class 8 - caustic and/or corrosive substances (CCS);
class 9 – other hazardous substances.
