Schedule 8 Identification of a major hazard facility
(Clause 175A)
Determination of threshold quantities
The following rules apply to the determination of threshold quantities from Table 1 and Table 2:(a) if the material is specifically listed in Table 1, the threshold quantity is to be determined from Table 1, and
(b) if a material is not specifically listed in Table 1, the appropriate threshold quantity is to be determined from Table 2 from the description which best applies to the material, and
(c) if more than one of the descriptions in Table 2 applies to a material, the description with the lowest threshold quantity is to be used.

Notes to Table 1.1 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 material that falls outside the UN number, for example, because it is too dangerous to transport or is part of a mixture covered by another UN number. However, any material that is covered by the listed UN numbers must be included in the quantity of the material named.
2 If a Schedule 8 material is part of a mixture, the equivalent quantity should be calculated as shown by Example 2 in Chapter 16 of the “National Code of Practice for the Control of Major Hazard Facilities” [NOHSC: 2016 (1996)].

3 Packing Group means the particular Packing Group determined from the current edition of the Australian Code for the Transport of Dangerous Goods by Road and Rail.
4 Materials referred to in the Table belong to a Class or Packing Group regardless of whether or not they are packaged for transport or under pressure.
5 The quantities specified for explosives relate to the weight of explosive exclusive of any non-explosive components.
6 If explosives of different Hazard Divisions are present in the same area or storage, all of the explosives shall be classified in accordance with Table 3 to this Schedule.
Table 3:
Determination of precedence of hazard division
Hazard Division | 1.1 | 1.2 | 1.3 | 1.4 | 1.5 | 1.6 |
1.1 | 1.1 | 1.1 | 1.1 | 1.1 | 1.1 | 1.1 |
1.2 | 1.1 | 1.2 | 1.1 | 1.2 | 1.1 | 1.2 |
1.3 | 1.1 | 1.1 | 1.3 | 1.3 | 1.1 | 1.1 |
1.4 | 1.1 | 1.2 | 1.3 | 1.4 | 1.5 | 1.6 |
1.5 | 1.1 | 1.1 | 1.1 | 1.5 | 1.5 | 1.5 |
1.6 | 1.1 | 1.2 | 1.1 | 1.6 | 1.5 | 1.6 |
Notes to Table 3.1 The precedence of hazard division of explosives of two different hazard divisions is the hazard division determined by taking the hazard division of one explosive in the vertical hazard division column of Table 3, and the hazard division of the other explosive in the horizontal hazard division column of the Table, and reaching the place in the Table where the two columns intersect.
2 If explosives of more than two hazard divisions are present together, the precedence of hazard division of those explosives is determined by taking any two of those hazard divisions and determining their precedence of hazard division in accordance with Note 1, then taking that collective hazard division and another of the hazard divisions and determining their precedence of hazard division in accordance with Note 1 and then continuing this process until all hazard divisions present have been considered.
