8 Reg. 9.2.1: S.R. No. 127/2000 as amended by S.R. No. 96/2005. - SCHEDULE 9

MAJOR HAZARD FACILITIES Regulation 1.1.5 MATERIALS AT MAJOR HAZARD FACILITIES
(AND THEIR THRESHOLD QUANTITY)

1. Definitions

In this Schedule- class has the same meaning as in the ADG Code; Packing Group
has the same meaning as in the ADG Code;

2. Relevant materials

The materials that characterise a workplace as a facility for the purposes of
these Regulations are the materials specifically mentioned in Table 1 and
materials that belong to the types, classes and categories mentioned in Table
2.

3. Threshold quantity of one material



3.1. In relation to each material referred to in clause 2, the third column of
each Table provides a quantity that is described as the threshold quantity of
that material.

3.2. If a material is mentioned in Table 1, the threshold quantity of the
material is that described in Table 1, whether or not the material also
belongs to a type, class or category mentioned in Table 2.

3.3. If a material is not mentioned in Table 1, and the material belongs to a
type, class or category mentioned in Table 2, the threshold quantity of that
material is that of the type, class or category to which it belongs.

3.4. If a material is not mentioned in Table 1, and the material appears to
belong to more than one of the types, classes or categories mentioned in Table
2, the threshold quantity of that material is that of the relevant type, class
or category which has the lower or lowest threshold quantity.

4. Threshold quantity of more than one material

If there is more than one material, a threshold quantity of materials exists
where, if a number of materials are present, the result of the following
aggregation formula exceeds 1- qx + qy + .... + qn Qx

Qy



Qn Where-
· x, y, ... and n are the materials present or likely to be present;
· qx, qy ..... and qn is the quantity of materials x, y, ... and n present or
likely to be present, other than-

   (i)  material that is present or likely to be present in an isolated
        quantity less than 2% of its individual threshold quantity;

   (ii) materials that are solely the subject of intermediate temporary
        storage, while in transit by road or rail;
· Qx, Qy ..... Qn is the individual threshold quantity for each material x, y
... and n;
· a material is present or likely to be present in an "isolated quantity", if
its location at the facility is such that it cannot, on its own, act as an
initiator of a major incident.

TABLE 1 The UN number listed against the named material is given for
information only. It does not restrict the meaning of the name, which also
applies to materials that fall outside the UN number, for example, because
they are too dangerous to transport or are part of mixtures covered by another
UN number. However, any materials that are covered by the listed UN numbers
must be included in the quantity of the material named.
