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. Check that M61 filters are properly installed. The most commonly recommended SPI consists of three HI-6/atropine auto-injectors, one diazepam auto-injector, two Reactive Skin Decontamination Lotion pouches, as well as a seven-day supply of pyridostigmine bromide or a supply of antibiotics, for each CAF member.

Physical state of wastes. Emergency Preparedness and Response Course Study with Quizlet and memorize flashcards containing terms like You are certain that your patient, who is now convulsing from nerve agent exposure Consult specialists if necessary. 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. In addition, use of ultraviolet light can increase the risk of skin cancer and eye damage; therefore, a qualified health professional should assess the benefits and risks associated with ultraviolet light prior to its use at a waste site. Personal Protective Equipment (PPE) is generally divided into two categories. What are the four methods of decontamination? Assume laminar flow. Administer the ATNAA. Stations should be separated physically to prevent cross contamination and should be arranged in order of decreasing contamination, preferably in a straight line. The following methods may be useful in assessing the effectiveness of decontamination. Pressurized sprayers for washing and rinsing, particularly hard-to-reach areas. Another way to test the effectiveness of decontamination procedures is to analyze for contaminants left in the cleaning solutions. These should be at least large enough for a worker to place a booted foot in, and should have either no drain or a drain connected to a collection tank or appropriate treatment system. A group of victims has been admitted to your triage unit. The sequence of stations is called the decontamination line. Shower facilities for full body wash or, at a minimum, personal wash sinks (with drains connected to a collection tank or appropriate treatment system). If worker leaves Exclusion Zone to change air tank, this is the last step in the decontamination procedure. What is the likely culprit? Another pair of tough outer gloves is often worn over the sleeves. Don the mitt and pick up sorbent pack 3. Boots, fully-encapsulating suit, inner gloves removed and deposited in separate containers lined with plastic. If Yes, (Arrow to third box below) Are the decontamination materials compatible with the materials to be decontaminated? Emergency Preparedness and Response Course, Emergency Preparedness and Response Course -, Emergency Preparedness Response Course (EPRC), Exercise Physiology: Theory and Application to Fitness and Performance, Edward Howley, John Quindry, Scott Powers, Williams' Basic Nutrition and Diet Therapy. 1.4 Decontamination lines are site specific since they are dependent upon the types of contamination and the type of work activities on site. Evaporation of volatile liquids can be enhanced by using steam jets. Wash patient with their clothing still on. The first step in decontamination is to establish Standard Operating Procedures that minimize contact with waste and thus the potential for contamination. Which of the following four decontamination planning factors is the commander using in the decision to decontaminate the weapons and ammunition before the support vehicles? Removal of electrostatically attached materials can be enhanced by coating the clothing or equipment with anti-static solutions. Washing with warm, soapy water.
