Salt/Fresh Water Contamination Test
Look for a white crystalline residue. If evidence of salt-water/fresh-water contamination is found, refer to
the procedures detailed below:
1. 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 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 insure the bag did
not get torn and the assembly was allowed to dry. Parachutes recovered using this method must be
rinsed NLT than 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:
a. Place the parachute assembly in a large watertight container filled with a suitable amount of
fresh, clean water to cover the assembly.
NOTE
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.
b. Agitate the container contents by hand for 5-minutes.
c.
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.
d. Repeat the procedures in steps 1 through 3 twice, using fresh, clean water for each rinse.
