It looks like the blanketing system has malfunctioned during a shutdown. Bull., 1985, (065), p. 25]. Several factors contribute to the highly hazardous styrene handling and polystyrene production process. The conventional method of producing styrene involves the alkylation of benzene with ethylene to produce ethylbenzene, followed by dehydrogenation of ethylbenzene to styrene. • Protect materials during handling and application to prevent damage or contamination. Reversible acute central nervous More than 85% of styrene is sorbed in 78 hrs on samples from a sandy aquifer(3). Red Flag This Post. B8 Special risks B9 Transportation, handling, storage .
