| Explosives building | Hazard type present | Table |
|---|---|---|
| Brick-built mounded building | Hazard Type 1 | Table 3 (mounded) |
| Brick-built unmounded building | Hazard Type 1 | Table 3(unmounded) |
| Metal-built mounded building without detonator annex | Hazard Type 1 | Table 4 |
| Metal-built unmounded building without attached detonator annex | Hazard Type 1 | Table 5A |
| Metal-built unmounded building with detonator annex | Hazard Type 1 | Table 5B |
| Building of any construction | Hazard Type 2 | Table 6 |
| Building of any construction | Hazard Type 3 | Table 7 |
| Building of any construction | Hazard Type 4 | Table 8 |
Where a building contains a mixture of Hazard Types 1, 3 or 4, add the quantities of the various hazard types together and treat as the lowest numbered hazard type for example treat 20 kg of Hazard Type 1 plus 30 kg of Hazard Type 3 as 50 kg of Hazard Type 1.
Where a building contains a mixture of Hazard Types 2, 3 or 4, add the quantities of the various types together and treat as the lowest numbered hazard. For example, treat 50 kg of Hazard Type 2 and 50 kg of Hazard Type 4 as 100 kg of Hazard Type 2.
Where a building contains a mixture which includes Hazard Type 1 and 2 with or without other hazard types, add the quantities of the various hazard types together and treat as Hazard Type 1 or Hazard Type 2, whichever requires the larger separation distance.
