STYRENE MONOMER : ENVIRONMENTAL, HEALTH & SAFETY Guidelines

6. Transport, Storage and Handling Operations

6.7. Previous cargoes and cleanliness

A tank that carries Styrene Monomer should not have carried the following substances as any of the last two cargoes:

  • Caustic soda
  • Pyrolysis gasoline
  • Fuel oils
  • Lube oils
Tanks to be loaded with Styrene Monomer should not be cleaned with materials which are reactive with Styrene Monomer or TBC, or cause increased colour, odour or a chloride problem. Salt water should never be the last wash because of possible chloride contamination.

Because of the effect of the application of heat to styrene, steam cleaning of adjacent tanks to compartments which contain styrene or styrene residues is strictly not allowed.
