Profile -- Cable Tool Drilling, 9/18/94contaminants is of the utmost importance. For this reason drilling using any method should be slowed toallow for greater control of the hazardous material being extracted from the hole.What are the physical requirements for workers?The noise level is 53 to 115 dBa [decibels adjusted], so hearing protection is required. Standardprotective gear is adequate at non-contaminated sites. Workers must be able to handle heavy equipment.Standard protective gear is adequate at non-contaminated sites. Workers must be able to handle heavyequipment.How many people are required to operate the technology?Though a cable tool rig can be operated by one person, at Hanford a helper is required for safety reasonsand to handle tooling.A geologist is also employed at most Hanford drilling sites to log samples. In areas of medium to highcontamination a Health Physics Technician (HPT) and a Site Safety Officer are needed to monitorcontamination levels. In areas of high contamination, an additional laborer is needed for contaminationcontrol and to decontaminate equipment.Public Health and Safety:What is the technology's history of accidents?No accident hazard to the public exists from operating this technology.If drilling in hazardous areas, use of proper containment techniques can eliminate hazardous releases.Infrequent releases of VOC vapor may occur at sites where the cable tool technique is used to drillthrough VOC-contaminated soil.Infrequent releases of VOC vapor may occur at sites where the cabletool technique is used to drill through VOC-contaminated soil.Does this technology produce routine releases of contaminants?If drilling in hazardous areas, use of proper containment techniques can eliminate hazardous releases.Are there potential impacts from transportation of equipment, samples, waste, or other materialsassociated with the technology?There are no impacts from transporting the drill rig. Contaminated cuttings and samples will be put indrums and may need to be transported for disposal or treatment.http://www.drilshop.com/holes/cabtool.html (9 of 13) [1/13/2005 12:48:35 PM]
