You may need this permit if you intend to manufacture, import, transport, supply, store, use or dispose of ammonium nitrate or another security-sensitive dangerous substance (e.g. type 3 fireworks, propellant or blasting explosive).
If you have employees, they will not need a separate permit, but you will need to nominate those employees who will have unsupervised access to the security-sensitive dangerous substance (responsible worker), and they will have to undergo security checks. If successful, they will be issued with an identity card that they must carry with them when working with the substance.
Please consult the Contact Officer for more information, including whether the ammonium nitrate or explosive substance you intend to work with requires this permit.
