15.20.1 The carriage temperature
of the cargo shall be maintained below 100°C to prevent the occurrence
of a self-sustaining, exothermic decomposition reaction.
15.20.2 The cargo may not
be carried in independent pressure vessels permanently affixed to
the vessel's deck unless:
-
.1 the tanks are sufficiently
insulated from fire; and
-
.2 the vessel has a water
deluge system for the tanks such that the cargo temperature is maintained
below 100°C and the temperature rise in the tanks does not exceed
1.5°C per hour for a fire of 650°C.
