SECURITY OF AMMONIUM NITRATE

1 SECURITY OF AMMONIUM NITRATEA Guide to theSecurity ofAmmonium Nitrateused in BlastingQuarry Leaflet 17/12/04 10:29 Page 32 SECURITY OF AMMONIUM NITRATEE ssential Guidelines Throughout this document AN meansany AMMONIUM NITRATE used for blastingpurposes. This document seeks to offer practicaland cost effective guidance, in line withHSE safety recommendations, to preventthe unlawful acquisition of ammoniumnitrate from quarries, mines and opencastsites. It is recommended that sites using ANfor blasting purposes should considercarefully the acquisition and storage ofthe product. Coordinating deliveries of ANwith blasting operations should allow youto limit the amounts of AN that arerequired to be stored at the site. Wherepossible, existing stocks of AN should bedepleted before fresh stocks are acquired. Consider using other blasting methodssuch as a blend supplied by contractorson the day of blasting so that AN neednot be stored on site at all.

2 Avoid storing outside where there ispublic access or where it is visible from aplace to which the public have access. Do not transfer/sell AN to others. Be familiar with and observe theguidance in the HSE safety document Storing and Handling AmmoniumNitrate INDG230. Record all AN deliveries - amounts,type and manufacturer. On receipt and if practical , considermarking AN bags with a unique reference( postcode) - this may assist theauthorities in identifying any recoveredAN. Record accurately all usage andreturns. Carry out regular stock checks againstwritten inventory. Report any theft/stock loss orsuspicious activity to police Leaflet 17/12/04 10:29 Page 43 Wherever possible and with regard toHSE guidance store AN in alockedcompound or building. Where AN is stored outside, alwaysfully cover to conceal the product and toassist in detecting any tampering. Maintain a list of persons authorised bythe site manager to access the AN storeand deny access to those who are notauthorised.

3 Maintain strictkey control for accessto stores of AN and ensure that the storekeys are themselves secured and can beaccounted for. Where AN stores are accessed by a key-code ensure that the code does notbecome known by unauthorised personsand change the code regularly. Ensure that existing SECURITY measuresare well maintained, regularly inspectedand working correctly fences,lighting, locks, alarms, CCTV OF AMMONIUM NITRATEQ uarry Leaflet 17/12/04 10:29 Page 94 FencingIf AN is to be secured in an externalcompound within the site then aneffective way is to construct thecompound using SECURITY fencing(recommended standards listed below),correctly installed and fitted withappropriate locking gate(s).The service life of fences will varydepending on the type of fence, theincidence of accidental or deliberatedamage combined with environmentalfactors and any should be given to HSEguidance relating to vehicle access andegress (in particular the risks associatedwith reversing/manoeuvring largevehicles).

4 It is strongly recommended that suchfences are fitted with a hostile toppingsuch as barbed wire, barbed tape orrevolving spikes to discourage , it is recommended that whereappropriate, a concrete sill is constructedbeneath the fenceline to prevent accessby that planning permission may berequired for such fenced enclosures andthere are restrictions and conditionsimposed by the Occupiers Liability Acts1957 and 1984 and Section 164 of theHighways Act OF AMMONIUM NITRATEQ uarry Leaflet 17/12/04 10:29 Page 65 Welded Mesh Anti-Intruder Fence Welded Mesh Anti-Intruder Fence should have a service life of at least 10 years if properlymaintained. It should be 3m high.

5 The fence should comply with BS1722 Part 10: 1990 SECURITY OF AMMONIUM NITRATEQ uarry Leaflet 17/12/04 10:29 Page 7 GatesGates should be of the same securitystandard as the fence that they areattached to and be fitted with anti-lifthinges. Consideration should be given tominimising gaps between posts and inparticular the clearance beneath thebottom edge of the gate(s) to preventunauthorised used to secure gates should beof the closed or concealed shackle type(unless a shroud is provided on the gateitself), be suitable for external use and betested or evaluated to BS EN Standard12320 or in BuildingsAN may be stored in buildings butcareful consideration mustbe given toHSE safety guidance relating toconfinement, ignition and fuel sources,ventilation and door-sets (which includes thedoor itself, door-frame, hinges and locks)giving access to buildings used to storeAN should be certified to a minimum ofLPS (Loss Prevention Standard) 1175 SECURITY Rating 2 or equivalent.

Windows which are particularlyvulnerable may be protected by externalsecurity grilles which should meet LPS1175 SR 2 or Shipping ContainersA fenced compound is recommendedsince it offers the best combination ofboth SECURITY and safety.

7 If ISO shippingcontainers are used they should beprovided with a vent with an open areaof at least this vent willreduce the likelihood that a fire in thecontainer will cause conditions that maylead to an explosion, storage in fencedcompounds is preferable. Measures tosecure the container so that it cannot bemoved must be Plant andMachineryIt is important that steps are taken toproperly secure any on-site tools, plantand vehicles that might be used to gainaccess to your AN store. Where possibletools should be locked away and mobileplant (such as ANFO mixers) and vehiclesshould be immobilised. It isrecommended that, where possible,ANFO mixers are drained of AN and oilwhen not in use to prevent Leaflet 17/12/04 10:29 Page 5 Produced by the National Counter Terrorism SECURITY Office in conjunction with QNJAC Useful FURTHER SPECIFIC ADVICE, PLEASE CONTACT YOUR LOCAL POLICESECURITY OF AMMONIUM NITRATEQ uarry Leaflet 17/12/04 10:29 Page 2
