SCHEDULE 3

[See rule 2(e) (iii), 5 and 6(1) (a)]
List of Hazardous Chemicals for Application of Rules 5 and 7 to 15

(a) The quantities set-out-below relate to each installation or group of installations belonging to the same occupier where the distance between the installations is not sufficient to avoid, in foreseeable circumstances, any aggravation of major-accident hazards. These quantities apply in any case to each group of installations belonging to the same occupier where the distance between the installations is less than 500 metres.

(b) For the purpose of determining the threshold quantity of a hazardous chemical in an industrial installation, account shall also be taken of any hazardous chemicals which is:-

    (i) in that part of any pipeline under the control of the occupier have control of the site, which is within 500 metres off that site and connected to it;

    (ii) at any other site under the control of the same occupier any part of the boundary of which is within 500 metres of the said site; and

    (iii) in any vehicle, vessel, aircraft or hovercraft under the control of the same occupier which is used for storage purpose either at the site or within 500 metres of it;

but no account shall be taken of any hazardous chemical which is in a vehicle, vessel, aircraft or hovercraft used for transporting it.
