2.6.2.2.4.5 The criteria for inhalation toxicity of vapours in 2.6.2.2.4.3 are based on LC50 data relating<br />

to 1 hour exposure, and where such information is available it shall be used. However, where only LC50 data<br />

relating to 4 hours exposures to the vapours are available, such figures can be multiplied by two and the product<br />

substituted in the above criteria, i.e. LC50 (4 hours) × 2 is considered to be the equivalent of LC50 (1 hour).<br />

2.6.2.2.4.6 Mixtures of liquids that are toxic by inhalation shall be assigned to packing groups according<br />

to 2.6.2.2.4.7 or 2.6.2.2.4.8.<br />
