Ethylbenzenng. Ethylbenzene is a flammable, colorless liquid with an aromatic odor. The flash point is 59 degrees Fahrenheit, and the currently established TLV is 100 ppm in air. It is currently not anticipated that the potential levels of exposure will reach personal exposure limit(PEL) or threshold limit value (TLV) limits, but this is based solely on limited available specific information. It is planned that inhala- tion and dermal contact will be the potential exposure pathways of concern. Protective clothing, including coveralls, boots, and gloves will bemandatory for all field operations personnel. In addition, respiratory protective devices shall be required to be within easy reach of those persons working in the Exclusion Zone or the Contamination Reduction Zone,should respiratory irritation occur. Should respiratory irritation occur, appropriate air-purifying respiratory y Protec- tive devices will be worn, with organic vapor cartridges and dust pre-filters, or with high efficiency organic vapor/HEPA stack type cartridge. Typically,-the—- i -- -cartridge will require-replacement daily. - - - — ---- J. 3100101/SSP.00W 4 October 17,1990
