BASIS say the explosion in Beirut has focussed attention on ammonium nitrate and the need to store it properly.

In a statement BASIS said the need for safe storage is well recognised in the UK and all FACTS advisers should be aware of storage requirements for ammonium nitrate (and all oxidising agents – any fertiliser with a yellow diamond marked ‘oxidising agent’ and ‘5.1’ on the bag).

Government advice on storage can be found here.

BASIS reiterate the ‘5 point plan’ that should always be followed:

1. Wherever possible use a Fertiliser Industry Assurance Scheme (FIAS) approved supplier.
2. Wherever possible keep in a secure area such as a building or sheeted away from public view.
3. Carry out regular stock checks and report any loss to the Police immediately (call 101).
4. Avoid leaving fertiliser in a field overnight – never leave fertiliser in the field for a long period of time.
5. Remember it is illegal to sell ammonium nitrate without the correct documentation
