Liquids having toxic vapours

Liquids having toxic vapours shall be assigned to the following packing groups, where “V” is the saturated vapour concentration in mℓ/m3 air at 20 °C and standard atmospheric pressure:

Packing group I:                If V ≥ 10 LC50 and LC50 ≤ 1,000 mℓ/m3.

Packing group II:               If V ≥ LC50 and LC50 ≤ 3,000 mℓ/m3, and do not meet the criteria for packing group I.

Packing group III:             If V ≥ 5/1 LC50 and LC50 ≤ 5,000 mℓ/m3, and do not meet the criteria for packing groups I or II.

Tear gas substances shall be included in packing group II even if their toxicity data correspond to packing group III values.
