Hands must be thoroughly washed upon leaving the work area and <br />before eating, drinking, or any other activities. <br />No facial hair, which interferes with the satisfactory fit of the <br />mask-to-face seal, is allowed on personnel. <br />Contact with contaminated or suspected contamination surfaces will be <br />avoided. Whenever possible, don't walk through puddles, mud and <br />other discolored surfaces; kneel on ground; lean, sit or place <br />equipment on drums, containers, vehicles, on the ground. <br />Medicine and alcohol can enhance the effects from exposure to toxic <br />chemicals. Prescribed drugs should not be taken by personnel where <br />the potential for absorption, inhalation, or ingestion of toxic <br />substances exists unless specifically approved by a qualified <br />physician. Alcoholic beverage intake offsite and during nonwork <br />hours will be minimized during Level C operations. <br />The number of individuals involved in drilling/sampling operations <br />will be kept to a minimum. Observers will stand a safe distance <br />upwind of drilling/sampling operations. No observers will be allowed <br />around the drill rig unless they are wearing OSHA/NIOSH approved <br />hardhats. If possible, drilling/sampling personnel will also <br />position themselves upwind of the sampling site while engaged in <br />drilling/sampling. <br />Nondisposable safety gear, sampling equipment, and drilling equipment <br />will be decontaminated before taken offsite. Drilling equipment can <br />be decontaminated by rinsing them free of soil and/or steam cleaning. <br />Washing with detergent solution followed by rinsing is preferred for <br />safety gear and sampling equipment. <br />During drilling ,and sampling operations for the Level C work, if <br />required, all personnel involved in the field operations will be <br />issued and will wear organic vapor monitors (3M Standard Model 3500 <br />or equivalent). At the end of the workday, these will be collected, <br />_identified by the wearer, and submitted by the Site Safety Officer <br />for submittal to the laboratory for analysis. A new vapor monitor <br />will be issued to each field personnel at the start of each day's <br />work shift. Compounds selected for analysis of the film badges <br />will include benzene, toluene, and ethylbenzene or three other <br />volatile organic solvents detected by the HNu meter or suspected of <br />being present. <br />During drilling and sampling operations for all borings, a portable <br />continuous,combustible gas analyzer will monitor the presence of <br />hydrocarbons. If during drilling and sampling, visable hydrocarbons <br />are detected or the combustible gas analyzer indicated 10% of the <br />Lower Explosive Level (LEL) work must stop and the hazard of <br />continuing the drilling will be assessed by the Site Safety Officer <br />and SPPL's safety representative. <br />Industrial first-aid kits will be onsite during all field operations.
