Prior to exiting a work area, personnel will wash their hands with soap and water in order to minimise the potential for contaminant exposure. 8.2.2 Modified Level D Personnel Decontamination Where work activities are performed in Modified Level D PPE (see Sections 5.2 and 7.2.2) personnel will perform decontamination using the following guidelines: Place tools, instruments, samples and trash at an appropriate location. The equipment drop area should be clean and dry and at a minimum, plastic bags should be available for trash. Waste PPE will not be placed in the same containers as general trash, Inspect equipment, samples, and if applicable,tools for signs of residual amounts of contamination or excessive soil buildup. If present, soils and contamination must be completely cleaned off of equipment, samples, and tools prior to removal from a work area, Personnel will visually check themselves for signs of excessive soils and possible contamination. If observed, soils and contamination will be completely removed before further decontamination is performed, Wash and rinse outer work gloves and boots(boot covers)with soap and water, Wash/brush off outer protective coverall(Tyvek TM), Untape wrists and ankles, Remove outer work gloves and place them in an appropriate container specified for waste PPE, Remove outer TyvekTM coveralls and place them in an appropriate container specified for waste PPE, Wash,rinse,and remove inner protective gloves and place them in an appropriate container specified for waste PPE,and Wash hands using soap and water(separate from other decontamination cleaners/solutions). 8.3 EQUIPMENT DECONTAMINATION Equipment to be decontaminated includes excavating equipment, tools, monitoring equipment, sampling equipment, and sample containers. General equipment decontamination consists of a soap and water wash, and a water rinse. If soap and water alone cannot remove contamination,additional procedures may be used such as steam cleaning. Tools: Tools will be dropped into a plastic pail, tub or other container in the Work Zone. They will be brushed off, rinsed, and transferred into a second pail to be carried to the decontamination station. Generally, tools will be washed with a detergent solution only,followed by a clean-water rinse.

The sampling tool will then be rinsed with deionized or distilled water and air dried. Heavy Equipment: Backhoe buckets and other equipment, which may contact contaminated soiWgroundwater, will be cleaned with high-pressure water or a portable high-pressure steam spray followed by a soap and water wash and rinse.
