:1 <br />E <br />SITE HEALTH & SAFETY PLAN <br />Toluene <br />This material is a flammable, colorless liquid, with a <br />benzol -like odor. The flash point is listed at 400F. <br />The currently established TLV is 100 ppm in air. <br />XYLENE <br />This material is a clear liquid with a flash point of <br />1000F. <br />The TLV is currently established at 100 ppm in air, and <br />is currently under study as a possible carcinogen. <br />It is currently not anticipated that the potential <br />levels of exposure will reach PEL or TLV limits, but <br />this is based solely on limited available specific <br />information. It is planned that inhalation and dermal <br />contact will be the potential exposure pathways of <br />concern. Protective hand coverings, including outer and <br />under gloves will be mandatory for all field operations <br />personnel. In addition, respiratory protective devices <br />shall be required to be available to each person in the <br />Exclusion Zone, or within easy reach of those persons <br />working in the Contamination Reduction Zone, should <br />irritating odors or irritation of respiratory tract <br />become detectable. <br />The appropriate air -purifying respiratory protective <br />devices, that are required to be available for all <br />personnel working on-site, will be fitted with organic <br />vapor cartridges and dust pre -filters, or with the high <br />efficiency, organic vapor/NEPA stack type cartridge. <br />Typically, if the respiratory protective devices are <br />worn, the cartridge will need to be changed daily. <br />If air monitoring at the breathing zone of the workers <br />is recorded to be 50 ppm or more (for total organic <br />compounds), the Project Safety officer will utilize <br />colormetric tubes (Drager, Sensidyne, etc.) for Benzene <br />specification. Provided no Benzene is detected, the <br />action level for increasing the level of protection from <br />level D to level C (including respiratory protection) <br />will be set at 200 ppm as measured at the breathing zone <br />of workers. If Benzene is detected, at any level, <br />respiratory protection will be required for all workers. <br />►0 <br />
