| Physico-chemical properties | ||
| Explosive | Solid, liquid, pasty or gelatinous substances and preparations which may also 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 and preparations which give rise to a highly exothermic reaction in contact with other substances, particularly flammable substances. | O |
| Extremely flammable | Liquid substances and preparations 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 and preparations, namely—
| F |
| Flammable | Liquid substancesand preparations having a low flash point. (See Note 2). | — |
| Health effects | ||
| Very toxic | Substances and preparations 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 and preparations which in low quantities cause death or acute or chronic damage to health when inhaled, swallowed or absorbed via the skin. | T |
| Harmful | Substances and preparations which may cause death or acute or chronic damage to health when inhaled, swallowed or absorbed via the skin. | Xn |
| Corrosive | Substances and preparations which, may on contact with living tissues, destroy them. | C |
| Irritant | Non-corrosive substances and preparations which, through immediate, prolonged or repeated contact with the skin or mucous membrane, may cause inflammation. | Xi |
| Carcinogenic (See Note 3) | Substances and preparations which, if they are inhaled or ingested or if they penetrate the skin, may induce cancer or increase its incidence. | |
