MC-4 RAM AIR FREE-FALL PERSONNEL PARACHUTE SYSTEM  SALT/FRESH-WATER CONTAMINATION TEST  0012 00  TM 10-1670-287-23&P  Personnel Required  THIS TASK COVERS:  INITIAL SETUP:  Equipment Condition  INSPECT CAUTION  NOTE Look for a white crystalline residue. If evidence of salt-water/fresh-water contamination is found, refer to  the procedures detailed below:  Laid out on packing table or other suitable area. 92R(10) Parachute Rigger Rinsing Parachute Assembly 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 which cannot  be rinsed within 48-hours after recovery, it will also be condemned, unless the following actions are  performed. Upon removal from the salt-water, the parachute is placed in a single heavy-duty plastic trash  bag, the top of the bag secured closed and kept in a wet state until a rinse can be performed following  normal rinse procedures. The bag must be doubled when outside temperatures exceed 85 degrees F. The bags must be inspected after transport and storage to ensure the bag did not get torn and the  assembly was allowed to dry. Parachutes recovered using this method must be rinsed NLT than seven  (7) days after the salt-water immersion or be condemned. However, if the cited time limitations can be  met, then immediately upon recover, 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 recover, under the supervision of a qualified parachute rigger (92R), rinse the recovered  parachute assembly as follows:  Equipment made of cotton fabric immersed in salt water is to be  condemned. Refer to WP 0011 00, INSPECTION, for equipment  disposition.  If the salt-water-soaked parachute assembly is too large to be  placed into a rinsing container, then the rinsing process will be  affected by applying fresh, clean water to the assembly using a  hose. 0012 00-1  3.  Remove the parachute assembly from the container and suspend or elevate it in a shaded area,  allowing a 5-minute drainage period. Do not attempt to wring the fabric or the suspension lines.  2.  Agitate the container contents by hand for 5-minutes.  1.  Place the parachute assembly in a large watertight container filled with a suitable amount of fresh,  clean water to cover the assembly.  x Inspect
