For the past 40 years, many home made explosives have been based on nitrogenous fertilisers. As the leading user of ammonium and ammonium nitrate-based fertilisers in the world, the UK has an important responsibility in keeping these materials safe from misuse. Blending, storing, transporting and using fertilisers all create opportunities for terrorists.
One simple way we can counter terrorism is simply by making it more difficult to get hold of the materials they need. If you store or transport fertiliser, be aware that it can be used for malicious ends and take steps to prevent it being stolen. Hauliers, importers, manufacturers, farmers and agricultural workers all have their part to play.
Regardless of the amount, we all have a responsibility to be vigilant and take security measures. You can find out more at the government website.
