Action level = 1/2 PEI.. Don half-face <br /> respirators (10x protection factor) if n1 ppm detected on PID (lowest detection of PID). Can use <br /> differentiating qualitative monitoring(Draeger,Gastech)to determine percentage of benzene being <br /> read by PID. Back out of work environment if PID reading multiplied by benzene pmentage exceeds <br /> 1 ppm. Re-evaluate alternate protection. <br /> 9)HAZARDOUS MATERIALS HANDLING PROCEDURES: <br /> All soil cuttings will be stored on-site in a 55-gallon drum pending results of soil sampling. An Hnu <br /> photoionization detector(PID)will be available to conduct air monitoring. <br /> 10)EMERGENCY PROCEDURES' <br /> An injured worrier will be immediately removed from the exclusion zone and decontaminated, if <br /> necessary. Minor emergencies will be transported by on-site personnel directly to the hospital noted <br /> below. Proper authorities will be notified(via 911)for major emergencies. <br /> Nearest telephone: <br /> Dan Dottai vehicle <br />
