Class 4.1 contains solids which are easily ignited by sparks or flames, (e.g nitrocellulose film) or which may contribute to fire or cause fire through friction. (e.g matches and desensitised explosives). Some substances may need to be refrigerated as they may be unstable if allowed to warm up.

This class also contains self-reactive and related substances that are liable to undergo strongly exothermic reaction and solid desensitised explosives that may explode if not ‘diluted’ properly.

All our Class 4 Dangerous Goods Labels are fully compatible with IATA/ ICAO, UN ADR/RID and IMDG/IMO requirements.
