ADR special packing provision B8

The pure substance may not go in IBCs: its vapour pressure is above 110 kPa (50 °C) or above 130 kPa (55 °C).

Where Table A assigns B8 with IBC02, the substance in its pure form may not be put in IBCs at all, because its vapour pressure is known to be above 110 kPa at 50 °C or above 130 kPa at 55 °C. The provision names no UN numbers; it attaches to the entry through Table A.

Note. Also printed in IBC03 (page 148) with the same effect; the only difference is the wording ("carried" instead of "transported").
