In this Schedule —

  • “brick-built” means having an outer structure which is wholly or mainly of brick, concrete, stone or other similar material;

  • “bridleway” has the same meaning as in the Highways Act 198036;

  • “distance”, save in the definition of “reference zone”, means the minimum distance;

  • “footpath” has the same meaning as in the Highways Act 1980;

  • “footway” has the same meaning as in the Highways Act 1980;

  • “lightly-used road” means a road used ordinarily by more than 20 and no more than 500 vehicles every 24 hours;

  • “major road” means a road used ordinarily by more than 10,000 vehicles every 24 hours;

  • “metal-built” means built wholly or mainly of steel or other metal;

  • “minor road” means a road used ordinarily by more than 500 vehicles every 24 hours, other than a major road;

  • “mounded” means surrounded by suitable mounds;

  • “place of public resort” means a place where more than one hundred persons are present, or are likely to be present, at any one time on a weekly or more frequent basis;

  • “reference zone” means the area around a store having the radius from the centre point of the store specified in column 5 of the relevant Table;

  • “road” means any thoroughfare on which the movement of vehicles is allowed ; and

  • “vulnerable building” means a building of four storeys or more above ground with a curtain-wall construction, that is to say where the masonry, glass or other cladding is suspended from the structural framework of the building.

2

Any reference in this Schedule to a thoroughfare (however described), waterway or railway line does not include any part of a thoroughfare, waterway or railway line within the site —

a

in which the store is situated; and

b

which are occupied by the person storing the explosives.

3

Any reference in this Schedule to a quantity of explosives shown in column 1 of a Table is to a quantity stored which is more than the lower figure but not more than the higher figure in column 1 in the same row of the Table.

4

Any reference in this Schedule to a building is to a building in or at which people are, or are likely to be, present either all the time or from time to time.

5

For the purposes of this Schedule, where explosives of different hazard types are in one store, the explosives shall be treated as belonging to the hazard type which would require the greatest separation distance for the total quantity of those explosives and the separation distance shall be determined in relation to that total quantity.

6

For the purposes of this Schedule, the radius for a reference zone applying in a particular case is the number in the entry in column 5 of the relevant Table corresponding to the quantity of explosives shown in column 1 of the Table.

7

For the purposes of this Schedule, any reference to “bridleway”, “footpath”, “footway” or “waterway” does not include, respectively, a bridleway, footpath, footway used, or waterway navigated, by no more than, ordinarily, 20 persons in any 24 hour period.

2

Where the storage is —

a

of hazard type 1 explosive in a brick-built mounded store, Table 1;

b

of hazard type 1 explosive in a brick-built unmounded store, Table 2;

c

of hazard type 1 explosive in a metal-built mounded store, Table 3;

d

of hazard type 1 explosive in a metal-built unmounded store with no detonator annex attached, Table 4;

e

of hazard type 1 explosive in a metal-built unmounded store with a detonator annex attached, Table 5;

f

of hazard type 2 explosive, some or all items being of more than 0.7 kg net mass, Table 6;

g

of hazard type 2 explosive, every item being of 0.7 kg net mass or less, Table 7;

h

of hazard type 3 explosive, Table 8;

i

of hazard type 4 explosive, Table 9,

shall apply, and any reference in this Schedule to a relevant Table is a reference to the Table which applies by virtue of this paragraph.

3

Subject to paragraphs 4 and 5, the distance between a store and any building, place of public resort or major road shall be the distance specified in the entry in column 2 of the relevant Table corresponding to the quantity of explosives shown in column 1 of the Table.

4

Subject to paragraph 5, where —

a

Table 1, 3, 4 or 5 applies; and

b

the number of dwellings in the reference zone is greater than the number specified in the entry in column 6 of the Table corresponding to the quantity of explosives shown in column 1 of the Table,

the distance between the store and any dwelling shall be the distance (if any) specified in the corresponding entry in column 3 of the Table.

5

The distance between a store and any vulnerable building shall be the distance (if any) specified in the column headed “Vulnerable building distance” corresponding to the quantity of explosives shown in column 1 of the relevant Table.

6

The distance between a store and —

a

any minor road or any railway line shall be half; and

b

any bridleway, footpath, footway, waterway or lightly-used road shall be one-third,

the distance shown in column 2 of the Table corresponding to the quantity of explosives shown in column 1 of the Table.
