4.1 Flammable solidsare readily comustible or may cause or contribute to fire through

friction, self-reactive substances which are liable to undergo astrongly exothermic reaction, solid desensitized explosives whichmay explode if not diluted sufficiently.

4.2 Substances liable to spontaneous combustionsolid and liquids which are liable to spontaneous heating under

normal conditions encountered in transport, or to heating up incontact with air, and being then liable to catch fire.

4.3 Substances which, in contact with water,emit flammable gasessolid and liquids wich by interaction with water, are liable to

become spontaneously flammable or give off flammable gases in

dangerous quantities.

Class 4 - FLAMMABLE SOLIDS

powdered, granular or pasty substances which are dangerous if theycan be easily ignited by brief contact with an ignition source,such as a burning match, and if the flame spreads rapidly.

Readily combustible solids

combustible solids and solids which may cause fire through friction.

4.1 Flammable solids

Self-reactive substancesAre thermally unstable substances liable to undergo a strongly

exothermix decomposition even without participation of oxygen.

Solid desensitized explosivesare explosives which are wetted with water or alcohols or arediluted with other substances to form a homogeneous solidmixture to suppress their explosive properties.
