SOP-003 Standard Operating Procedure Equipment Decontamination Procedures Page 1 of 3 Revision No.1 April 2019 Sharpe Army Depot 1.0 Objective Decontamination is performed as a quality assurance measure and safety precaution. It helps prevent cross-contamination among samples and helps maintain a clean working environment for the safety of field personnel. 2.0 Equipment and Materials Needed • Cleaning liquids such as soap or detergent solutions (Liquinox or equivalent), potable water and distilled water • Cleaning brushes • Cleaning containers such as plastic buckets or tubs • Pump sprayers for dispensing rinse waters • A high-pressure hot water sprayer for cleaning large equipment (e.g. drilling equipment) • Waste containers as outlined in SOP-007, Investigation Derived Waste Management • Health and safety equipment as outlined in the Accident Prevention Plan 3.0 Methodology Small, reusable equipment is decontaminated mainly by rinsing with liquids that include soap or detergent solutions, potable water, and distilled water. Steam cleaning should be used whenever visible contamination exists on large machinery/vehicles. Following decontamination, if the equipment is not to be reused immediately, it should be stored and protected from recontamination by wrapping in aluminum foil or plastic as necessary. 3.1 Pre-Sampling Decontamination Activities • Don the appropriate personal protective equipment, including nitrile gloves, as specified in the Accident Prevention Plan and as required for the specific work area. • Assemble containers and equipment for decontamination. • Decontaminate new equipment or equipment not previously decontaminated before use. Disposable equipment, including polyethylene tubing and bailers, do not require decontamination prior to use. • Rinse equipment not previously decontaminated and appropriately wrapped in aluminum foil before the next use. If the protective wrapping on a piece of pre-cleaned equipment has been torn or if there is a question of its cleanliness, the equipment should be considered contaminated and undergo full decontamination procedures before use.
