If No, (Arrow to box to the right) Report to Superiors for Instructions. Gloves and boots should be tucked under the sleeves and legs of outer clothing, and hoods (if not attached) should be worn outside the collar. Eliminate leaks by making minor strap adjustments. Large galvanized tubs, stock tanks, or children's wading pools to hold wash and rinse solutions. The decontamination process should consist of a series of procedures performed in a specific sequence. 6. If Yes, (Arrow to second box below) Are the decontamination materials compatible with the hazardous substances present? Shower if highly toxic skin-corrosive or skin-absorbable materials are known or suspected to be present. For each CBRN message type, there are three set identifiers - (M) mandatory, (C) conditional and (O). HZ is a weak acid. He has been feeling ill since his return from safari in Africa a few days ago.

Each procedure should be performed at a separate station in order to prevent cross contamination. Patient is alert and oriented during the exam. Treatment of patients suffering from pulmonary agent exposure should focus on? 2. Surface contaminants may be easy to detect and remove; however, contaminants that have permeated a material are difficult or impossible to detect and remove. Mission-oriented protective posture (MOPP) provides commanders a flexible system of individual protective equipment (IPE). Decontamination methods either (1) physically remove contaminants, (2) inactivate contaminants by chemical detoxification or disinfection/sterilization, or (3) remove contaminants by a combination of both physical and chemical means. Remove inner gloves and deposit in container with liner. 8. Correct definition of Mission-Oriented Protective Posture (MOPP), A flexible system of individual protective equipment (IPE) and clothing that provides the maximum CBRN protection with the lowest risk to achieve mission accomplishment. Ultraviolet light can be used to observe contamination of skin, clothing, and equipment; however, certain areas of the skin may fluoresce naturally, thereby introducing an uncertainty into the test. Emergency responders are taught how to recognize and mitigate attacks from such weapons. Decontamination methods either (1) physically remove contaminants, (2) inactivate contaminants by chemical detoxification or disinfection/sterilization, or (3) remove contaminants by a combination of both physical and chemical means.

Two arrows continue from the second divided Decon rectangle to a circle marked with an X that has an upward pointing arrow, that turns back toward the dashed HOTLINE to an area labelled Redress: Boot Covers and Outer Gloves, and crosses the dashed HOTLINE. (A series of three arrows in the upper right, one arrow 20 degrees above and the other arrow 20 degrees below the central arrow, indicate wind direction toward the HOTLINE.) The filter service life indicator turns blue. Continuous rinsing with large volumes will remove even more contaminants than multiple rinsings with a lesser total volume. Containers to hold contaminants and contaminated soil removed from tires and the undersides of vehicles and equipment. Repeat as often as necessary. If the upper plate moves with a velocity of 0.02ft/s0.02 \mathrm{ft} / \mathrm{s}0.02ft/s, at what distance from the bottom plate does the maximum velocity in the gap between the two plates occur?
