Category of danger | Property (See Note 1) | Symbol-letter |
Notes 1. As further described in the approved classification and labelling guide. 2. The categories are specified in the approved classification and labelling guide. 3. In certain cases specified in the approved supply list and in the approved classification and labelling guide substances classified as dangerous for the environment do not require to be labelled with the symbol for this category of danger. | ||
PHYSICO-CHEMICAL PROPERTIES | ||
Explosive | Solid, liquid, pasty or gelatinous substances, which may react exothermically without atmospheric oxygen thereby quickly evolving gases and which, under defined test conditions, detonate, quickly deflagrate or upon heating explode when partially confined. | E |
Oxidizing | Substances which give rise to a highly exothermic reaction in contact with other substances, particularly flammable substances. | O |
Extremely flammable | Liquid substances having an extremely low flash point and a low boiling point and gaseous substances and preparations which are flammable in contact with air at ambient temperature and pressure. (See Note 2.) | F+ |
Highly flammable | The following substances— (a) substances which may become hot and finally catch fire in contact with air at ambient temperature without any application of energy, (b) solid substances which may readily catch fire after brief contact with a source of ignition and which continue to burn or to be consumed after removal of the source of ignition, (c) liquid substances having a very low flash point, or (d) substances which, in contact with water or damp air, evolve highly flammable gases in dangerous quantities. (See Note 2.) | F |
Flammable | Liquid substances having a low flash point. (See Note 2.) | None |
HEALTH EFFECTS | ||
Very toxic | Substances which in very low quantities cause death or acute or chronic damage to health when inhaled, swallowed or absorbed via the skin. | T+ |
Toxic | Substances which in low quantities cause death or acute or chronic damage to health when inhaled, swallowed or absorbed via the skin. | T |
Harmful | Substances which may cause death or acute or chronic damage to health when inhaled, swallowed or absorbed via the skin. | Xn |
Corrosive | Substances which may, on contact with living tissues, destroy them. | C |
Irritant | Non-corrosive substances which, through immediate, prolonged or repeated contact with the skin or mucous membrane, may cause inflammation. | Xi |
Sensitizing | Substances which, if they are inhaled or if they penetrate the skin, are capable of eliciting a reaction by hypersensitization such that on further exposure to the substance or preparation, characteristic adverse effects are produced. | |
Sensitizing by inhalation | Xn | |
Sensitizing by skin contact | Xi | |
Carcinogenic (See Note 3) | Substances which, if they are inhaled or ingested or if they penetrate the skin, may induce cancer or increase its incidence. | |
Category 1 | T | |
Category 2 | T | |
Category 3 | Xn | |
Mutagenic (See Note 3) | Substances which, if they are inhaled or ingested or if they penetrate the skin, may induce heritable genetic defects or increase their incidence. | |
Category 1 | T | |
Category 2 | T | |
Category 3 | Xn | |
Toxic for reproduction (See Note 3) | Substances which, if they are inhaled or ingested or if they penetrate the skin, may produce or increase the incidence of non-heritable adverse effects in the progeny and/or an impairment of male or female reproductive functions or capacity. | |
Category 1 | T | |
Category 2 | T | |
Category 3 | Xn | |
Dangerous for the environment (See Note 4) | Substances which, were they to enter into the environment, would present or might present an immediate or delayed danger for one or more components of the environment. | N |
