This may include <br />manual removal of gross contamination with shovels or other tools, followed by a high-pressure, hot water <br />sprayer. Because decontamination at the high-pressure, hot water station poses the possibility of a splash <br />and/or mist inhalation hazard, the task should be performed using Level D personal protective equipment <br />at a minimum. <br />Field tool including split-barrel soil samplers, brass liners, and sample knives and trowels will be <br />decontaminated. The field tools may be scrubbed visually clean using a detergent solution <br />(Alconox/Liquinox) with water and a stiff, long-bristled scrub brush. Following the solution scrubbing, <br />the tools may be rinsed with distilled water or isopropyl alcohol. <br />Equipment Decontamination <br />Gross Removal By: <br />X Hand Scrubbing <br />Cold High Pressure Wash <br />Hot High Pressure Wash <br />Steam Cleaning <br />Other (specify) <br />X Clean Rinse <br />X Decon solution (specify) Alconox solution <br />7.3 Disposition of Decontamination Wastes <br />All materials and equipment used for decontamination should be disposed of in accordance with local, <br />State, and/or Federal Regulations.
