What do I need to do? - additional

Step 1 Identify what products are stored on the farm

Part1: Dangerous substances

Part 2: Ammonium nitrate (AN) fertilisers

NB: Not all ammonium nitrate fertiliser will carry an oxidising symbol. Those that do not have a symbol are not classed as dangerous substances.

19 different hazard warning symbols

Step 2: Do I need to notify?

What do you store or intend storing? Notify local Fire & Rescue Service Notify enforcing authority (HSE/LA) Mark site entrance with warning sign
A and B Yes Yes Yes
A only Yes Yes Yes
B only Yes No No
Neither A nor B No No No

Key

A - 25 tonnes or more of dangerous substances.

B - 150 tonnes or more of ammonium nitrate mixtures, where the nitrogen content (N) exceeds 15.75% of the mixture by weight (and the AN is not a dangerous substance).

Example scenarios

You make a note of the type and quantity of all products that carry a hazard warning symbol and the total amount of ammonium nitrate fertiliser.

Example 1:

You have:

  • 2 tonnes of flammable liquids
  • 5 tonnes of corrosive substances,
  • 8 tonnes of toxic substances, and
  • 200 tonnes of ammonium nitrate fertiliser where the nitrogen content is more than 15.75%. (70 out of the 200 tonnes carry the oxidising hazard symbol).

You add up the combined total of the products which have a hazard warning symbol to give the total amount of dangerous substances (2+5+8+70). This adds up to 85 tonnes of dangerous substances. You are also storing 200 tonnes of ammonium nitrate fertiliser.

Action: Using the table above, you are storing both A and B and must therefore notify HSE and your local Fire and Rescue Service. You must also mark the entrance of your site with a warning sign. Complete the notification form which can be downloaded from this site.


Example 2

You have:

  • 3 tonnes of corrosive substances
  • 2 tonnes of harmful substances
  • 5 tonnes of combustible substances, and
  • 500 tonnes of ammonium nitrate fertiliser where the nitrogen content is more than 15.75%. (10 out of the 500 tonnes carry the oxidising hazard symbol).

In this example you are storing 20 tonnes (3+2+5+10) of dangerous substances. You are also storing 500 tonnes of ammonium nitrate fertiliser.

Action: Using the table above, you are storing B only and must therefore notify your local Fire and Rescue Service (not HSE). Complete the notification form which can be downloaded from this site.


Example 3

You have:

  • 3 tonnes of liquids marked ‘dangerous for the environment’
  • 3 tonnes of toxic substances,
  • 9 tonnes of harmful substances, and
  • 50 tonnes of ammonium nitrate fertiliser where the nitrogen content is more than 15.75%. (None of the 50 tonnes carry the oxidising hazard symbol).

In this example you are storing 15 tonnes (3+3+9+0) of dangerous substances. You are also storing 50 tonnes of ammonium nitrate fertiliser.

Action: Using the table above, you are storing ‘neither’ (eg no quantities of A nor B which are above the notification thresholds). You do not therefore need to notify.
