Monitoring Well Installdnon Report Page 1 <br /> Appendix A <br /> Project No.336.2 <br /> h3 November 13, 1995 <br /> i <br /> 1.0 HEALTH AND SAFETY PROGRAM <br /> Geological Technics has incorporated the following health and safety precautions while working on <br /> sites containing unidentified hazardous waste. Once the nature and extent of contamination has been <br /> determined,additional work on site will be met with the proper 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 excavation site. <br /> The working perimeter will be marked by brightly colored delineators. All unauthorized personnel <br /> will not be allowed access into the work space. <br /> The project supervisor will coordinate all field activities and maintain the safest possible working <br /> environment at all times. If an emergency occurs, the supervisor will immediately contact the proper <br /> 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 gloves <br /> will be changed after each sample has been collected. <br /> f<i Used disposable clothing will be properly discarded at the end of each working day. <br /> Hard 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 /> .': During drilling and excavation activities, the working air space will be periodically monitored with <br /> either a Photo Ionization Detector (PID) or SKC Color-Detector Tubes (Draeger Tubes) for gas and <br /> vapor content. The PID measures the total organic compounds(VOC)vapor concentration while the <br /> Detector Tubes measures the levels of specific compounds in the air being sampled. Monitoring of <br /> 1 the working air space shall be concentrated around the drilling rig and in the down wind direction. <br /> ' J <br /> If working air space concentrations exceed the Permissible Exposure Limits, then the workers will <br /> j wear respirators with organic vapor cartridges. <br /> If working air space at the perimeter of the working space has levels that exceed the Permissible <br /> Exposure Limits for more then 15 minutes, then the drilling or excavation activity will halt until the <br /> concentrations can be maintained below the Permissible Exposure Limits. <br />
