Q

Considerations when marking the survivor’s position

A
  • Should fuel be evident or suspected in the water, smoke flares should not be used. Flares may ignite the fuel.
  • Use caution not to strike survivor when deploying marking device from aircraft.
  • Avoid dropping smoke flares upwind of survivor as fumes are caustic.
  • Deploy two smoke or sea markers
  • DIFAR sonobuoy may be used to mark survivors by maritime patrol aircraft. Tune RF 15 and use directions finder.

  • Life rafts available
  • Hypothermia
67
Q

Hydrostatic squeeze

A

Constriction of the respiratory system in response to hypothermia.

Added stress to the body of being hoisted by the rescue strop allows gravity to take the blood pooled in the chest and head and disperse it to the extremities. This can/will send survivor into respiratory and/or cardiac arrest.

Consider using a method of recovery that maintains a horizontal or near horizontal position.

68
Q

After drop

Cold blood from extremities gets suddenly reintroduced to the body’s core, and drops the body’s core temp below level needed to sustain life.

Recovery:

  • Rescue basket
  • Litter
  • DD double lift

Transport:

boom = 1000 lbs.
hook = 3000 lbs.

73
Q

the limit switches are inoperative in backup control

76
Q
