AECOM Decon SOP <br /> Standard Operating Procedure (SOP) <br /> Decontamination <br /> 1 .0 Purpose and Applicability <br /> AECOMs SOP describes the methods to be used for the decontamination of items that <br /> may become contaminated during field operations. Decontamination is performed as a <br /> quality assurance measure, and as a safety and health precaution. It prevents cross- <br /> contamination between samples and also helps maintain a clean working environment. <br /> Equipment requiring decontamination may include hand tools, monitoring and testing <br /> equipment, personal protective equipment (PPE), or heavy equipment (e.g., loaders, <br /> backhoes, drill rigs, etc.). <br /> Decontamination is achieved mainly by rinsing with liquids, which may include soap <br /> and/or detergent solutions, tap water, distilled water, and methanol or isopropyl alcohol. <br /> Equipment may be allowed to air dry after being cleaned or may be wiped dry with paper <br /> towels or chemical-free cloths. <br /> All sampling equipment will be decontaminated prior to use and between each sample <br /> collection point. Waste products produced by the decontamination procedures, such as <br /> rinse liquids, solids, rags, gloves, etc., will be collected and disposed of properly, based <br /> on the nature of contamination and site protocols. Any materials and equipment that will <br /> be reused must be decontaminated or properly protected before being taken off site. <br /> Specific project requirements as described in an approved Work Plan, Sampling Plan,Job <br /> Hazard Analysis (JHA), or Site-Specific Health and Safety Plan (HASP) will take <br /> precedence over the procedures described in this document. <br /> 2.0 Responsibilities <br /> It is the responsibility of the field sampling coordinator to ensure that proper <br /> decontamination procedures are followed and that all waste materials produced by <br /> decontamination are properly managed. It is the responsibility of any subcontractors <br /> (e.g., drilling or sampling contractors) to follow the designated decontamination <br /> procedures that are stated in their contracts and outlined in the project HASP. It is the <br /> responsibility of all personnel involved with sample collection or decontamination to <br /> maintain a clean working environment and to ensure that no contaminants are <br /> inadvertently introduced into the environment, tracked out of the contamination reduction <br /> zone (CRZ), or passed from one sample point to another. <br /> SOP Decontamination 1 of 4 <br />
