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—
(a) substances and preparations which may become hot and finally catch fire in contact with air at ambient temperature without any application of energy,
(b) solid substances and preparations 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 substancesand preparations having a very low flash point, or
(d) substances and preparations which, in contact with water or damp air, evolve highly flammable gases in dangerous quantities. (See Note 2).
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.

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

Xn
Corrosive
Substances and preparations which, may on contact with living tissues, destroy them.
C
