The Ammonium Nitrate Materials (High Nitrogen Content) Safety Regulations 2003
These Regulations, which extend to Great Britain, implement article 7 of Council Directive 80/876/EEC (OJ No. L250, 23.9.80 p. 7) in providing for checks to be carried out by the enforcing authority to establish that any ammonium nitrate based fertiliser manufactured chemically and containing more than 28% by weight of nitrogen, and described as an `EC fertiliser' satisfies the detonation resistance test (regulation 8(2) and Schedule 2). They also introduce equivalent safety controls for other ammonium nitrate material, where the material contains more than 28% nitrogen by weight derived from ammonium nitrate unless a person who has such material (that is not sold or to be used as a fertiliser) has been granted an exemption certificate by the Health and Safety Executive (`HSE') in accordance with regulation 10.
