Dressing stations for entry to the CRZ should be separate from redressing areas for exit from the CRZ. Removal of adhesive contaminants can be enhanced through certain methods such as solidifying, freezing (e.g., using dry ice or ice water), adsorption or absorption (e.g., with powdered lime or kitty litter), or melting. U.S. Army Equipment Information. The amount, location, and containment of contaminants. General Guide to Solubility of Contaminants In Four Solvent Types. Determine the decontamination equipment needed. A series of numbered hexagons point downward toward the CONTAMINATION CONTROL LINE.) Avoid cold water which tends to close skin pores, trapping radioactive contamination. A patient who works at an insecticide manufacturing plant is admitted to the emergency room. Chlorine bleach is a widely used method for decontamination, however, chlorine bleach is quite potent and can cause severe damage to the skin and even blindness if contact occurs in your eyes. Separate flow patterns and stations should be provided to isolate workers from different contamination zones containing incompatible wastes. Drains or pumps for collection of contaminated wash and rinse solutions. Various decontamination methods are listed in Table 1. Rinse off decon solution using water. For example, workers using a steam jet may need a different type of respiratory protection than other decontamination personnel because of the high moisture levels produced by steam jets. Methods of Disinfection Many disinfectants are used alone or in combinations (e.g., hydrogen peroxide and peracetic acid) in the health-care setting.
