PART VCRITERIA FOR ASCERTAINING PACKING GROUPS OF GOODS WHICH HAVE BEEN CLASSIFIED AS TOXIC SUBSTANCES IN ACCORDANCE WITH REGULATION 5 OF THESE REGULATIONS
Toxic substances shall be allocated into packing group I, II or III in accordance with the criteria given in the table below:
| (1) | (2) | (3) | (4) | (5) |
|---|---|---|---|---|
| Packing grouip | Oral toxicity LD50 (mg/kg) | Dermal toxicity of LD50 (mg/kg) | Inhalation toxicity of dust or mists LC50 (mg/m3) | Inhalation toxicity of vapours where V is the saturated vapour concentration produced by the substance at 20°C expressed by reference to LC50 (ppm) |
The above criteria are based on LC50 data relating to one hour exposure and where such information is available it should be used. However, where only LC50 data relating to 4 hour exposures is available, then: LC50 (4 hr) × 4 shall be considered equivalent to LC50 (1 hr) for dusts or mists, and LC50 (4 hr) × 2 shall be considered equivalent to LC50 (1 hr) for vapours. | ||||
| I | ≤5 | ≤40 | ≤500 | V≥10 × LC50 and LC50≤1000 |
| II | >5 to ≤50 | >40 to ≤200 | >500 to ≤2000 | V≥LC50 and LC50 ≤3000 but not placed in packing group I |
| III | solids: >50 to ≤200 liquids: >50 to ≤500 | >200 to ≤1000 | >2000 to ≤10000 | V≥0.2 × LC50 and LC50 ≤5000 but not placed in either packing group I or II |
