B CDIM Standard Operating Procedure ,M SOP 5.0 Equipment Decontamination E N 0 1 N E E E I X 0 Rev. 0 10/23/20 sophisticated designs involving self-contained metal decontamination pads in combination with bermed polyethylene sheeting may also be used, depending on project-specific requirements. These requirements, along with specific equipment and construction specifications for the decontamination zone, will be provided in the project work plans. 6. NON-DEDICATED SAMPLING EQUIPMENT DECONTAMINATION Each piece of reusable, non-dedicated sampling equipment will be decontaminated before each sampling event. The standard procedure will be performed as described below. • Suitable personal protective equipment (specified by the project work plans) must be worn by all personnel involved with the task to reduce personal exposure. • Heavily caked soil and/or other material will be scraped or brushed from equipment. Steam cleaning of equipment may be required to remove material in some cases. • Equipment that will not be damaged by water should be placed into a wash tub containing a laboratory-grade detergent solution and scrubbed with a brush or clean cloth. A two-stage rinsing process will then be conducted with fresh, potable water, followed by deionized water. • Methanol, hexane, and HPLC water rinses may then follow for some sampler components when specified by the project work plans. • Any equipment that may be damaged by submersion into water will be wiped clean using a sponge and detergent solution. Cleaning will be followed by wiping the equipment with deionized water. • Air dry the rinsed equipment. Soil organic vapor (SOV) sampling equipment should be flushed dry with bottled air of known quality and/or as per the project work plans. • Place decontaminated equipment on clean plastic sheeting to prevent contact with contaminated soil. If equipment is not used immediately, cover or wrap the equipment in clean plastic sheeting or bags to minimize airborne contamination. • Decontamination activities will be documented on the daily Field Activity Log (FAL)or other appropriate form(s), as specified by the project work plans. 7. DEDICATED SAMPLING EQUIPMENT DECONTAMINATION Dedicated sampling equipment, such as submersible pumps, will be decontaminated prior to installation inside monitoring wells. At a minimum, the procedure outlined below must be performed. If factory-cleaned, hermetically sealed materials are used, no decontamination will be necessary, provided that laboratory decontamination certification is available upon receipt of the equipment. • Suitable personal protective equipment will be worn by all personnel involved in the task, in accordance with the project work plans. 3
