Schedule 15—Hazardous chemicals at major hazard facilities (and their threshold quantity)
Chapter 9
1—Definitions
In this Schedule—
Class has the same meaning as in the ADG Code;
Division has the same meaning as in the ADG Code;
Packing Group has the same meaning as in the ADG Code;
subsidiary risk has the same meaning as in the ADG Code.
2—Relevant hazardous chemicals
The hazardous chemicals that characterise a workplace as a facility for the purposes of these regulations are the chemicals specifically referred to in table 15.1 and chemicals that belong to the types, classes and categories referred to in table 15.2.
3—Threshold quantity of one hazardous chemical
(1) In relation to each hazardous chemical referred to in clause 2, column 3 of tables 15.1 and 15.2 provides a quantity that is described as the threshold quantity of that chemical.
(2) If a hazardous chemical is referred to in table 15.1, the threshold quantity of the chemical is that described in table 15.1, whether or not the chemical also belongs to a type, class or category referred to in table 15.2.
(3) If a hazardous chemical is not referred to in table 15.1, and the chemical belongs to a type, class or category referred to in table 15.2, the threshold quantity of that chemical is that of the type, class or category to which it belongs.
(4) If a hazardous chemical is not referred to in table 15.1, and the chemical appears to belong to more than 1 of the types, classes or categories referred to in table 15.2, the threshold quantity of that chemical is that of the relevant type, class or category which has the lower or lowest threshold quantity.
4—Threshold quantity of more than 1 hazardous chemical
If there is more than 1 hazardous chemical, a threshold quantity of chemicals exists where, if a number of chemicals are present, the result of the following aggregation formula exceeds 1:
where—
(a) x, y, [....] and n are the hazardous chemicals present or likely to be present;
(b) qx, qy, [....] and qn is the total quantity of hazardous chemicals x, y, [....] and n present or likely to be present, other than—
(i) a hazardous chemical that is present or likely to be present in an isolated quantity less than 2% of its threshold quantity;
(ii) hazardous chemicals that are solely the subject of intermediate temporary storage, while in transit by road or rail (unless it is reasonably foreseeable that, despite the transitory nature of the storage, hazardous chemicals are or are likely to be present frequently or in significant quantities);
(c) Qx, Qy, [....] and Qn is the individual threshold quantity for each hazardous chemical x, y, [....] and n;
(d) a hazardous chemical is present or likely to be present in an isolated quantity, for the purposes of paragraph (b)(i), if its location at the facility is such that it cannot, on its own, act as an initiator of a major incident.
5—How table 15.1 must be used
(1) The UN number listed in table 15.1 against the named hazardous chemical does not restrict the meaning of the name, which also applies to hazardous chemicals that fall outside the UN number.
1 The hazardous chemicals are too dangerous to be transported.
2 The hazardous chemicals are part of mixtures covered by a different UN number.
(2) Any hazardous chemicals that are covered by the listed UN numbers must be included in the quantity of the chemical named.
6—How table 15.2 must be used
(1) The quantities specified for explosives in table 15.2 relate to the weight of explosive exclusive of packagings, casings and other nonexplosive components.
(2) If explosives of different hazard divisions are present in the same area or storage, all of the explosives must, before table 15.2 is applied, be classified in accordance with the following table:
