0 • <br /> 1.0 HEALTH AND SAFETY PLAN <br /> Geological Technics has incorporated the following health and safety precautions while <br /> working on sites containing unidentified hazardous waste. Once the nature and extent of <br /> contamination has been determined, additional work on site will be met with the proper <br /> precautions. <br /> 1.1 Workers Health and Safety <br /> 1.1.1 Work Space Safety <br /> The perimeter of the workspace should, if possible, be 20 feet from the drilling rig or <br /> excavation site. Brightly colored delineators will mark the working perimeter. All <br /> unauthorized personnel will not be allowed access into the workspace. <br /> The project supervisor will coordinate all field activities and maintain the safest possible <br /> working environment at all times. If an emergency occurs, the supervisor will immediately <br /> contact the proper authorities. <br /> 1.1.2 Skin and Head Protection <br /> Disposable suits, boots, and gloves will be worn when the working conditions require such <br /> precautions. <br /> Disposable plastic gloves will be wom at all times during soil and groundwater sampling. <br /> The gloves will be changed after each sample has been collected. <br /> Used disposable clothing will be properly discarded at the end of each working day. <br /> Hard hats will be wom during drilling, excavation, and other activities in which potentially <br /> dangerous equipment is being operated within the workspace. <br /> 1.1.3 Face and Respiratory Protection <br /> During drilling and excavation activities, the working air space will be periodically <br /> monitored with a Photo Ionization Detector (PID) for gas and vapor content. The PID <br /> measures the total organic compounds (VOC) vapor concentration while the Detector Tubes <br /> measures the levels of specific compounds in the air being sampled. Monitoring of the <br /> working air space shall be concentrated around the drilling rig and in the down wind <br /> direction. <br /> If working air space concentrations exceed the Permissible Exposure Limits, the workers will <br /> wear respirators with organic vapor cartridges. <br /> If working air space at the perimeter of the working space has levels that exceed the <br /> Permissible Exposure Limits for more then 15 minutes, then the drilling or excavation <br /> activity will halt until the concentrations can be maintained below the Permissible Exposure <br /> Limits. <br />
