A worker develops frostbite on their fingers after working outdoors in extreme cold. The OFA attendant should:

Accepted Answer

Protect the area from further cold and avoid rewarming if refreezing is possible

Answer

Frostbitten tissue should not be rewarmed in the field if there is a risk of refreezing, as thaw-refreeze cycles cause severe tissue damage.
