Geological Technics In Page 1 <br /> Appendix A <br /> Project No.251.2 <br /> December 20,1995 <br /> 1.0 HEALTH AND SAFETY PROGRAM <br /> Geological Technics has incorporated the following health an&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 work space should,if possible, be 20 feet from the drilling rig or <br /> excavation site. The working perimeter will be marked by brightly colored''delineators. All <br /> unauthorized personnel will not be allowed access into the work space. <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 worn at all.times during soil and groundwater sampling. The <br /> j 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 /> fHard hats will be worn during drilling, excavation, and other activities in''Which potentially <br /> dangerous equipment is being operated within the work space. <br /> 1.1.3 Face and Respiratory Protection <br /> t During drilling and excavation activities, the working air space will be periodically monitored <br /> with either a Photo Ionization Detector(PID) or SKC Color-Detector Tubes (Draeger Tubes)for <br /> gas and vapor content. The PID measures the total organic compounds(VOC)vapor <br /> concentration while the Detector Tubes measures the levels of specific compounds in the air <br /> being sampled. Monitoring of the working air space shall be concentrated around the drilling <br /> rig and in the down wind direction. <br /> y <br /> t <br /> If working air space concentrations exceed the Permissible Exposure Limits; then the workers <br /> will wear respirators with organic vapor cartridges: <br /> If working air space at the perimeter.of the working space has1evels that exceed the <br /> Permissible Exposure Limits for more then 15 minutes, then the drilling or excavation activity <br /> will halt until the concentrations can be maintained below the Permissible Exposure Limits. <br /> i <br /> r <br /> 1 <br />
