Equipment Decontamination SOP Equipment Decontamination SOP 1 Q Scope/Applicability: This standard operating procedure (SOP)provides guidance for preventing,minimizing, or limiting cross-contamination of samples due to inappropriate or inadequate equipment decontamination, and for developing decontamination procedures for sampling equipment to be used during fieldwork activities at contaminated sites. This procedure minimizes the possibility of exposure to field personnel from the handling of improperly decontaminated equipment, but it does not address personnel decontamination. This procedure is applicable to sampling and non-sampling equipment used at contaminated sites. 2.0 Summary: This procedure entails removing or neutralizing contaminants from equipment in order to minimize the likelihood of sample cross contamination, reduce or eliminate transfer of contaminants to clean areas, or prevent the mixing of incompatible substances. Gross contamination can be removed by physical decontamination procedures. These abrasive and non- abrasive physical decontamination methods include the use of brushes, solvents, and rags. The decontamination procedure may be summarized as follows: • Initial physical removal. • A non-phosphate detergent wash. • A tap-water rinse. • A distilled/deionized water rinse. • Optional: A ten (10)percent acid rinse (ONLY used if samples are collected for metals analyses) followed by a distilled/deionized water rinse. • Optional: A solvent rinse (ONLY used if samples are collected for organics analyses). • Air dry(if time allows). 3_0 Health and Safety: The Health and Safety considerations for conducting this procedure are described in the following documents: • Site Health and Safety Plan—H&S Plan Templates • Job Safety Analysis—Decontamination Specific health and safety considerations for this procedure include: • For some decontamination procedures, the solvents used(e.g., isopropyl alcohol, acetone, methanol) raise health and safety, and waste disposal concerns. • Health and safety considerations associated with this procedure are addressed during the Job Safety Analysis.
