Code Characteristics
H1 Explosive
An explosive substance is a waste, whether solid or liquid and is likely to produce gas by any chemical reaction generating temperature and pressure which may be harmful for the individuals or environment .
H 3 Flammable liquids
Flammable liquids are liquids, or mixtures of liquids, such as paints, varnishes, lacquers, which produce a flammable vapor at temperatures of 60º C.
H 4.1 Flammable solids
Solids, or waste solids, other than those classed as explosives, which may be readily combustible, or may cause fire through friction, during its transportation.
H 4.2 Substances or wastes liable to spontaneous combustion
Substances or wastes which are known for spontaneous heating even at room temperature during the transport, or for heating by coming in contact with air resulting in fire.
H 4.3 Substances or wastes which, in contact with water emit flammable gases
Substances or wastes which, may become spontaneously flammable or produce flammable gases in dangerous quantities.
H 5.1 Oxidizing
Substances or wastes which are not combustible themselves but may contribute to the combustion or other materials by yielding oxygen.
H 5.2 Organic Peroxides
Organic substances or wastes which contain the bivalent-o-o-structure are thermally unstable substances which may undergo exothermic self-accelerating decomposition.
H 6.1 Poisons
Substances or wastes which may cause death or serious injury or harm the human health if swallowed or inhaled or by skin contact.
H 6.2 Infectious substances
Substances or wastes containing viable micro-organisms or their toxins which are known or suspected to cause disease in animals or humans.
H 8 Corrosives
Substances or wastes which, by chemical action, will cause severe damage when in contact with living tissue, or, in the case of leakage, will materially damage, or even destroy, other goods or the means of transport; they may also cause other hazards.
H 10 Liberation of toxic gases in contact with air or water
Substances or wastes which, by interaction with air or water, are liable to give off toxic gases in dangerous quantities.
H 11 Toxic (delayed or chronic)
Substances or wastes which, if they are inhaled or ingested or if they penetrate the skin, may involve delayed or chronic effects, including carcinogenicity).
H 12 Eco-toxic
Substances or wastes which if released, present or may present immediate or delayed adverse impacts to the environment by means of bioaccumulation or toxic effects upon biotic systems or both.
