With the entering
into force of the new regulations on the movement of dangerous goods (ADR,
RID, IMDG), a new type of dangerous substances has been included in class 4.1,
i.e. polymerising substances.
With this new type of
dangerous goods, the concept of self-accelerating polymerisation temperature
(SAPT) has been introduced, meaning the lowest temperature at which the polymerisation
of a substance may occur in the packaging, IBC or tank as delivered for
transport.
Without
stabilisation, polymerising substances are liable to undergo an intense
exothermic reaction resulting in the formation of larger molecules or polymers
under normal conditions of transportation.
Further details on the goods’ properties are included in the issue
208 of Vdl and in the new IMDG Regulations, amendment 38-16.
