Specified chemical substance which may <br />be present include petroleum hydrocarbons (i.e.. naDhtha)(and its <br />constituents inculding trichloroethane and tetraethyl), benzene, toluene, <br />ethyl benzene, xylene. and tetraethyl lead. Based on the field <br />operations to be performed, sit Personnel may be exposed to a range of <br />physical hazards, including heat stress. noise, open excavations, <br />operating equipment. vehicle hazards. contact with live utilities. <br />flammable/explosive atmospheres. and related hazards. <br />Although most phases of the protect may only require Level D protecticn <br />for field personnel, some activities may necessitate the use of Leve'_ C <br />protection. Depending on the presence of chemical contamination, the <br />following tasks may require the use of Level C protection: tank opening <br />and checking of contents, pumping/removal of tank residuals, excavation <br />and sampling of contaminated soils, decontamination, of tank surfaces, Air <br />pruifying respirators (APRs) shall be used for any operation, or in any <br />work area where total ionizable hYdrocarbon concentrations exceed 10 p8m <br />Similarly. APRs shall also be worn anytime airborne concentrations of <br />benzene are identified above 0.5 PPm, as detected using color indicatiOng <br />tubes for benzene. <br />Regardless of individual task safety reQUlrement6. all operations shall <br />be performed in compliance with the Federal OSHA Hazardous Waste <br />Operations and Emegency Response standard, 29 CFR 1910.120 and the <br />equivalent Cal -OSHA standard, 8 CCR 5192. <br />Tne project is anticipated to begin in Nov. 3, 1993end is expected to be <br />completed in approximately three months.
