6.13.1. Reactive Products
Products having known reactivity with styrene should not be loaded in cargo
tanks, which have a common bulkhead (also corner-to-corner), pump or
transfer piping.
6.13.2. Separate Systems
Tanks containing styrene shall have separate pumping and piping systems
which should not pass through other cargo tanks containing incompatible
cargoes and have separate vapour return lines.
6.13.3. Temperature
Styrene should not be loaded into cargo tanks adjacent or corner-to-corner
to a cargo having a temperature of 30°C (86°F) or higher. Heating styrene
to above this temperature will reduce shelf life and increase the risk of polymerisation in
the cargo tank.
6.13.4. Heating coils
Heating coils in tanks carrying styrene shall be blinded off.
6.13.5. Edible products
Edible products shall never be loaded with bulkhead to bulkhead contact
with styrene and piping systems should be entirely separate.
In addition, review US Coast Guard compatibility charts (Title 46, Code of Federal
Regulations, part 150).
