Substances not accepted for carriage
Chemically unstable substances of Class 8 shall not be accepted for carriage unless the necessary
precautions have been taken to prevent the possibility of a dangerous decomposition or
polymerization under normal conditions of carriage. For the precautions necessary to prevent
polymerization, see special provision 386 of Chapter 3.3. To this end particular care shall be taken to
ensure that receptacles and tanks do not contain any substances liable to promote these reactions.
The following substances shall not be accepted for carriage:
- UN No. 1798 NITROHYDROCHLORIC ACID;
- chemically unstable mixtures of spent sulphuric acid;
- chemically unstable mixtures of nitrating acid or mixtures of residual sulphuric and nitric
acids, not denitrated;
- perchloric acid aqueous solution with more than 72% pure acid, by mass, or mixtures of
perchloric acid with any liquid other than water.
