STYRENE MONOMER : ENVIRONMENTAL, HEALTH & SAFETY Guidelines

6. Transport, Storage and Handling Operations

6.13. Barges and Sea Operations / Cargo separation for safety purposes

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).
