Personnel Required Two, 92R (10) Parachute Rigger INSPECTION Look for a white crystalline residue. If evidence of salt-/fresh-water contamination is found, refer to the procedures detailed below: Rinsing Equipment Immersed in Salt-Water. If the parachute, or any of its components, has been immersed in salt-water in excess of 24-hours it will be condemned. Additionally, if the parachute, or any of its components, has been immersed in salt-water for a period less than 24-hours, but cannot be rinsed within 48- hours after recover, it will also be condemned. However, if the cited time limitations can be met, then immediately upon recovery, suspend or elevate the parachute assembly in a shaded area and allow it to drain for at least 5-minutes. Do not attempt to wring the fabric or the suspension lines. Within 48-hours after recovery, under the supervision of a qualified parachute rigger (92R), rinse the recovered parachute. Items found or known to be contaminated are to be cleaned in the following manner: 1. Place equipment in a large watertight container filled with a suitable amount of fresh, clean water to cover item(s). CAUTION Equipment made of cotton fabric immersed in salt-water is to be condemned. Refer to WP 0009 00, INSPECTION, for equipment disposition. NOTE If salt water-soaked equipment is too large to be placed in a rinsing container, then the rinsing process will be affected by applying fresh, clean water using a hose on the item. 2. Agitate container contents by hand for 5-minutes. 3. Remove item(s) from container and suspend or elevate equipment in a shaded area, allowing a 5-minute drainage period. Do not attempt to wring equipment fabric or, if applicable, suspension lines. 4. Repeat procedures 1. through 3., above, twice, using fresh, clean water for each rinse.
