TM 5-6630-215-12 (f). A yellow color in the upper layer equal to or darker than the yellow band on the bottle is a positive test for G agents and for certain toxic insecticides. A yellow color in the lower water layer indicates very dangerous concentrations of G agents. With time, the yellow band on the bottle may fade, in this case, a comparison may be made with the yellow band on the Reagent X plastic tube used for the chlorine demand test. (g) Rinse the bottle “P” (fig. 2-25) and fill to the 25 ml mark on the bottle. Add 2 tablets from the orange capped vial I and shake to dissolve. Add 1 level scoop of powder from the gray capped vial J followed immediately by 1 tablet from the dark green capped vial H. Place the plastic capon the bottle and shake well for 2 minutes. Continue as specified in steps (e) and (f). (h) In the absence of a highly positive chlorine demand test, no color or a color lighter than the yellow band indicates a negative agent. (6) Taste and Odor Test. (a) If the arsenic test, para 2-24b(1) mustard test (2) above, chlorine demand test 2-22K(2) and G-agents test 2-24b(1) are negative and if the pH test (4) above is 6 or above, carefully smell and taste a sample of the water specimen. (b) A positive test is indicated by: A lacrimatory or chlorine odor. A biting and/or peppery chlorine taste. Any taste or odor of a known war gas. (c) Absence of all tastes and odors will indicate a negative result, but not necessarily a safe water. A negative test is also indicated by the presence of only those odors and/or tastes normally characteristic of natural waters. 2-24.1 WATER TESTING KIT CHEMICAL AGENTS-M272 (Not Used in Buys 1 and 2).
