When the extent of contamination cannot be readily determined, cleaning <br /> should be done according to the assumption that the equipment is highly contaminated. <br /> Standard operating procedures listed below describe the method for full field <br /> decontamination. If different technical procedures are required for a specific project, they <br /> will be spelled out in the project plans. <br /> Such variations in decontamination may include all or an expanded scope of these <br /> decontamination procedures: <br /> • Remove gross contamination from the equipment by brushing and then rinse <br /> with tap water. <br /> • Wash with detergent or soap solution (e.g., Alconox and tap water). <br /> • Rinse with tap water or distilled water. <br /> • Rinse with reagent grade methanol or isopropyl alcohol. <br /> • Rinse with deionized water (distilled water is an acceptable substitute if <br /> deionized water is unavailable). <br /> • Repeat entire procedure or any parts of the procedure as necessary. <br /> • After decontamination procedure is completed, avoid placing equipment <br /> directly on ground surface to avoid re-contamination. <br /> SOP Decontamination 3 of 4 <br />
