Businesses in the explosives sector manufacture, store, supply or use explosive materials for authorised commercial and industrial purposes. Products may include explosives used in quarrying, mining, tunnelling and demolition, along with detonators and related blasting equipment. Some businesses specialise in supplying materials, while others provide services such as blast planning, controlled blasting, site assessment and the removal or management of explosive materials. These activities are subject to strict controls because of the risks involved. Depending on their role, businesses may need licences or other permissions covering the manufacture, storage, supply, transport or use of explosives. In Great Britain, the Health and Safety Executive administers key explosives licensing requirements and publishes guidance on safe management.
