If decontamination can be performed without interfering with essential life-saving techniques or first aid, or if a worker has been contaminated with an extremely toxic or corrosive material that could cause severe injury or loss of life, decontamination must be performed immediately. If Yes, (Arrow to second decision diamond to the right) Contaminants Extremely Hazardous? What level of civilian chemical equipment would healthcare providers don when providing initial medical treatment after an incident but not involved with decontamination? There is no reliable test to immediately determine how effective decontamination is. A health physicist should be consulted if this situation arises. Select the important steps that you should take. For example, proper procedures for dressing prior to entering the Exclusion Zone will minimize the potential for contaminants to bypass the protective clothing and escape decontamination. Long-handled, soft-bristled brushes to help wash and rinse off contaminants. You suspect Lewisite. U.S. Army Equipment Information. 8. Physical methods involving high pressure and/or heat should be used only as necessary and with caution since they can spread contamination and cause burns. The chapter does not cover decontamination of radioactively contaminated personnel or equipment. A patient presents to the hospital. Another way to test the effectiveness of decontamination procedures is to analyze for contaminants left in the cleaning solutions. In general, all fasteners should be used (i.e., zippers fully closed, all buttons used, all snaps closed, etc.) Personal Protective Equipment (PPE) is generally divided into two categories. Be incompatible with the hazardous substances being removed (Le., a decontamination method may react with contaminants to produce an explosion, heat, or toxic products). Calculate (a) the partial pressure of each gas in atmospheres and (b) the concentration of each gas in mol/L at 0 C (Hint: Because volume is proportional to the number of moles present, mole fractions of gases can be expressed as ratios of volumes at the same temperature and pressure.). skin-corrosive or skin-absorbable materials are known or suspected to be present. A series of numbered hexagons point downward toward the CONTAMINATION CONTROL LINE.) 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. 5.

Cover equipment and tools with a strippable coating which can be removed during decontamination. In some c-ases, decontamination personnel should wear the same levels of PPE as workers in the Exclusion Zone. Take a deep breath and hold it. If symptoms persist, seek assistance. The primary toxicity of pulmonary agents is to the _____ and follows _____ of smoke, particles, valors, or gases. MULTISERVICE TACTICS, TECHNIQUES, AND PROCEDURES FOR NUCLEAR, BIOLOGICAL, AND CHEMICAL (NBC) PROTECTION. How is the victim of nerve agent exposure presenting with convulsions classified? The longer a contaminant is in contact with an object, the greater the probability and extent of permeation. Decontamination protects workers from hazardous substances that may contaminate and eventually permeate the protective clothing, respiratory equipment, tools, vehicles, and other equipment used on site; it protects all site personnel by minimizing the transfer of harmful materials into clean areas; it helps prevent mixing of incompatible chemicals; and it protects the community by preventing uncontrolled transportation of contaminants from the site. A dashed line cutting vertically through this rectangle indicates the HOTLINE. 10. Patient presents with 5-day-old blisters/rash mostly on the arm, face, and hands. horizontal parallel plates as shown in Fig. Dusts and vapors that cling to equipment and workers or become trapped in small openings, such as the weave of the clothing fabrics, can be removed with water or a liquid rinse. 1.41010B)1.21051.2 \times 10^{-5} Place in container with liner.
