above 30 ppmv. All readings will be recorded in a field notebook. 10. 120MENCY RESPONSE PLAN Emergency Procedures listed in this plan are designed to give the field personnel instruction on how to handle medical emergencies and fires and explosions. The emergency procedures will be carefully reviewed with the field team during the health and safety training session. The field personnel will be instructed to seek immediate professional medical attention for all serious injuries. A first aid kit and manual will be present at the project site in case of minor injuries. 10.1 Fire and Explosion Hazards Fires on site are of particular concern during soil drilling and sampling activities during the possibility of encountering flammable petroleum hydrocarbon liquids and vapors. During these activities the Site Safety Officer will be present and equipped with a multipurpose (A, B, C, ) fire extinguisher. Flammable materials will be cleared away from the site prior to the start of work. If a fire does occur, the local fire dept. will be contacted immediately. 10.2 Activities Shutdown Under extreme circumstances the on-site supervisor, safety officer, or project manager may require that field operations be temporarily suspended while an underlying hazard is corrected or controlled. If vapor measurements with the explosive vapor monitor show levels approaching explosive limits, operations will be stopped while the situation is controlled. During this activity, personnel will be evacuated from the area to prevent exposure to fugitive vapor emissions or injury in the event of an explosion. The Site Safety Officer will have ultimate authority for both the shutdown and later resumption of the field activities. 10.3 Co:sunity Protection To assure the community is protected from health and fire hazards, up wind and down wind vapor monitoring will be performed if the general work area has hydrocarbon levels exceeding 100 ppmv. If down wind monitoring indicates persistent levels of 30 ppmv at the perimeter of the work area, work will be shutdown and vapor control efforts will be instituted until measurements indicate levels have dropped below 30 ppmv. An alternative approach of expanding the taped off area zone may be used to provide additional community protection. 9
