-11 to -25 -> Frostbite possible without proper clothing.
-26 to -65 -> Exposed flesh frostbite possible in 60 seconds
-66 or less -> Exposed flesh frostbite possible in less than 60 seconds for the average person.
BE ALERT TO FROSTBITE CONDITIONS
 |
Exposed skin can freeze within 1 minute at wind-chill equivalent temperatures below -25 F. |
|
Frostbite affects the extremities,such as fingers and toes. |
|
If a body part has been frostbitten once, it is more susceptible to frostbite again, even in milder conditions. |
|
Redness and a burning sensation are indications frostbite will occur unless the extremity is warmed. |
|
Numbness is an indication that frostbite has already taken place. |
|
If frostbite is discovered, hold the affected part tightly against the warm skin or another part of the body; (for example place frozen fingers under arm). |
|
When thoroughly warmed, keep covered and make an effort to keep area from freezing again. |
