M and M Automotive <br /> November 1994 <br /> Site Specific Safety Plan Soil Boring/Sampling <br /> WES Project No. 4070-T Well Installation <br /> Drilling Safety <br /> The following safety measures must be followed during drilling/boring activities: <br /> 1. Underground utilities such as gas and water mains and electrical lines <br /> should be located prior to drilling. , <br /> 2. The presence of underground structures such as crypts, tanks, vaults, <br /> etc. should be determined. <br /> 3. Drill rigs should not be positioned within three feet of excavations <br /> where caving might occur. <br /> 4. Overhead clearance of masts, kellys and other structures should be <br /> pre-determined. <br /> S. Drilling rigs should not be erected within ten feet of overhead power <br /> lines. <br /> 6. The potential for the emanation of toxic and ignitable vapors during <br /> drilling is possible. Therefore, monitoring for suspected <br /> contaminants and/or combustible vapors is required. Drilling ` <br /> activities should be secured and sources of ignition secured if I' <br /> combustible vapor levels in excess of 10% of the LEL are encountered. ' <br /> I <br /> 7. Set brakes and chock wheels of portable rigs prior to operation. <br /> 8. Loose clothing and long loose hair should not be worn in the vicinity of <br /> rotating augers, kellys or other equipment. <br /> 9. Guards and drive shields should not be removed. <br /> r <br /> 10. Exhaust from engines or other combustion units should be directed <br /> away from the work area. <br /> 11. Wearing protection must be worn at all times during operations. <br /> 12. Since recovery of the sampler encompasses repeated manipulation of <br /> the drill rig and sampler, workers are alerted to exercise extreme <br /> caution white performing these tasks. <br /> 13. Most tasks involving the drill rig and sampling devices are repetitive <br /> and extra care should be taken to protect hands and fingers while <br /> working with heavy machine driven equipment. <br /> 14. No worker shall handle soil samples or cuttings without wearing the <br /> proper protective equipment. f <br /> a <br /> a <br />
