  • Propylene oxide
  • Styrene
  • BEIs: Arsenic (elemental and soluble inorganic compounds); Benzene; Carbon disulphide; Carbon monoxide; Chromium VI (hexavalent chromium), water-soluble fume; Ethyl benzene; Fluorides; Mercury (elemental); 4,4-Methylene bis(2-chloroaniline) (also known as MOCA, MBOCA); 4-4-Methylene diphenyl diisocyanate (MDI); Methyl isobutyl ketone (MIBK); Pentachlorophenol (PCP); Phenol; Tetrahydrofuran (THF); Toluene diisocyanate-2,4- or 2,6- or mixture of isomers (TDI); Toluene; Trichloroethylene (TCE).
