Project No. 014-94276 Page No. 20 eye wash will be available for thisu ose. Instruction will p rp also be provided to wash any skin areas with soap and water if direct contact with contaminants has occurred. During normal field activities work clothes may become e wet. If a field team member's clothing becomes saturated with an obviously contaminated liquid sludge the possibility for dermal exposure to contaminants may exist. Under these circumstances, that field team member will change out of the contaminated clothing clean off any residual liquid/sludge with water and change into clean clothing of the proper level of protection. a 11.2 Fire and Explosion Hazards Fires are of particular concern during this investigation due to the possibility of encountering flammable petroleum hydrocarbon liquid or vapors. An adequate multi-purpose (A,B,C) fire extinguisher will be located on-site on the drill rig at all times. The local fire department will be notified by a Kraz n & Associates representative of the location and anticipated activities in order to provide a more timely response in the event of an emergency. In the remote chance that a fire does occur, the local fire department will be notified immediately. Additional I calls to the main office of Krazan & Associates will be mad . The project director would then notify the client. I 11.3 DWrations Shutdown Under certain extremely hazardous situations the Task Leader, Project Director, Task Safety Officer, may request that field operations be temporarily suspended while the underlying hazard is corrected or controlled. i During any sampling or drilling activity breathing zone PID measurements for hydrocarbons will be performed. If these levels exceed 50 ppmv, detector tubes will be used to further quantify the benzene vapors present. If the level of benzene is detected above 0.5 ppmv or PID readings are consistently in i excess of 50 ppmv, respirators will be required and monito ing will be performed every 30 minutes. If PID measurements above 1400 ppmv occur in general area or at well head, a potential fire or explosion hazard may exist. Under these circumstances activities will be stopped until these levels are brought down. l This may be accomplished by containerizing contaminated soils or liquids, covering contaminated soil, a foam, visquene, or with clean soil to isolate the source.
