CBRN stands for Chemical, Biological, Radiological and Nuclear. Sodium nitrite can increase methemoglobin levels, which will decrease blood oxygenation. In addition, this chapter provides general guidelines for designing and selecting decontamination procedures at a site, and it presents a decision aid for evaluating the health and safety aspects of decontamination methods. Decontamination - the process of removing or neutralizing contaminants that have accumulated on personnel and equipment - is critical to health and safety at hazardous waste sites. Deposit in container with plastic liner. Remove tape around boots and gloves and deposit in container with plastic liner. If a decontamination method does pose a direct health hazard, measures must be taken to protect both decontamination personnel and the workers being decontaminated. Volatile liquids. Human decontamination is the process of removing hazardous materials from the human body, including chemicals, radioactive substances, and infectious material. 6. 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. 2. At a hazardous waste site, decontamination facilities should be located in the Contamination Reduction Zone (CRZ), i.e., the area between the Exclusion Zone (the contaminated area) and the Support Zone (the clean area) as shown in 3. These cleaning solutions normally utilize one or more of the following methods: Dissolving contaminants.

Wear disposable outer garments and use disposable equipment where appropriate. During an emergency, provisions must also be made for protecting medical personnel and disposing of contaminated clothing and equipment. Contaminants that can be removed by physical means can be categorized as follows: Physical removal of gross contamination should be followed by a wash/rinse process using cleaning solutions. The decontamination of large numbers of casualties is currently most often . If No, (Arrow to box to the right) Report to Superiors for Instructions. Tilt head, open eyelids wide, and pour water into left and right eyes so water run off side of face.

During hot weather operations, a cool down station may be set up within this area. All victims have recently been in an area where canisters A patient is suffering from painful, highly corrosive burns similar to acid, and wheals have begun to appear on the skin. 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.
