Substances that must be stabilised for transportation by temperature control in order to prevent dangerous reactions are not permitted for transportation by air according to special provision A209.

In the case of chemical stabilisation, special provision A209 must also be observed. This substance was therefore assigned special provision A209 for the Dangerous Goods Database in addition to the information in Table 3-1.

If, when transported in packagings, the substance has a self-accelerating polymerisation temperature (SAPT) of more than 75°C and a heat of reaction not exceeding 300 J/g, this special provision need not be taken into account. BAM does not have any concrete values for this. It was therefore decided to list the special provision here.
