DECONTAMINATION <br /> Decontamination consists of contamination-reduction phases and personal hygiene for site <br /> operations. The following decontamination procedures will be used: <br /> • Maximize the use of disposable clothing for personal protection (latex surgical <br /> gloves, Tyvek coveralls and PVC booties). <br /> • Remove disposable PVC booties,Tyvek coveralls,outer gloves and inner gloves <br /> and dispose of them in a clean unused garbage bag(s). <br /> • Remove respirator,remove cartridges and discard them. Return respirator to <br /> storeroom at the end of the job. All respirators will be properly washed, sanitized, <br /> tagged and stored. <br /> • The garbage bag(s) holding disposable items from the site operations will be <br /> placed in securely covered,clearly marked 55-gallon steel drums and placed in an <br /> area of the site at the direction of the Site Engineer. Final disposition will be in <br /> accordance with site remedial action. <br /> • Wash hands and face with soap immediately upon exiting the Exclusion Zone. <br /> • After departing the site, site operations personnel should shower as soon as <br /> possible. <br /> • After departing the site, fabric work clothes and undergarments should be washed <br /> as soon as possible using routine wash method. <br /> • Each piece of equipment(tools and all vehicles taken inside the exclusion zone) <br /> must be decontaminated before it leaves the operation site. This must be done in <br /> an area designated for equipment decontamination. Large items of equipment, <br /> such as backhoes, vehicles and trucks, should be subjected to decontamination by <br /> high pressure water washes or steam. A special solution, such as Liqui-Nox, a 1% <br /> to 2% TSP solution, or Bola Degreaser,may have to be used on sampling <br /> equipment or heavily soiled items. All wash and rinse water must be contained <br /> (on Visqueen for large equipment, in 5-gallon buckets for tools),collected, and <br /> disposed of as required. <br /> • For decontamination of personnel involved in an accident, refer to the Emergency <br /> Procedures section of this document(page 9). <br /> PHYSICAL HAZARDS <br /> The physical hazards associated with operating heavy equipment are as follows: <br /> • Moving machine parts <br /> • Heavy Equipment <br /> • Noise <br /> • Exposure to contaminated particulate matter while moving excavated soil <br /> • Possible contact with gas or power lines during excavating <br /> page 8 <br />
