5.7 Decontamination Procedures <br /> Depending on the specific job task, decontamination may include personnel themselves, sampling <br /> equipment, and/or heavy equipment. The specified level of protection for a task (A,B,C, or D) <br /> does not in itself define the extent of personal protection or equipment decontamination. For <br /> instance, Level C without dermal hazards will require less decontamination than Level C with <br /> dermal hazards. And, heavy equipment will always require decontamination to prevent cross- <br /> contamination of samples. The following sections summarize general decontamination protocols. <br /> 5.7.1 HeM Equipment <br /> Heavy equipment will be decontaminated prior to personnel decontamination. Drillers will <br /> steamclean their augers after use preferably at locations near the individual drilling operations. <br /> Hand auger buckets will be washed in TSP solution and rinsed in distilled water. Contaminant <br /> systems will be set-up for collection of decon fluids and materials. Berms and wind barriers will <br /> be set up if appropriate. <br /> Vehicles that become contaminated with suspect soil will be cleaned prior to leaving the site. The <br /> wheel wells, tires, sides of vehicles, etc. will be high-pressure washed at a location to be <br /> determined by the SSO. <br /> 5.7.2 Personnel <br /> Use steps and procedures outlined below as guidelines for personnel decontamination: <br /> • Brush loose soil from body; <br /> • Boot removal (where appropriate); <br /> • Suit removal (where appropriate); <br /> • Respirator/hard hat removal (where appropriate); <br /> • Respirator wash (where appropriate); <br /> • Glove removal; <br /> • Field wash hands <br /> 5.7.3 Samples and Sampling Equipment <br /> The same decontamination line will be used for sampling equipment decon as is used for <br /> personnel decon. At a minimum the following is performed: <br /> 23 <br />
