Do remember this......The skin helps to regulate body temp.....
Excessive cooling can lead to HYPOthermia. Especially of the larger and more serious burns.
Our 'local' burn center (in Tampa) doesn't want us using the burn gel packs on burns greater than 15% BSA (Body Surface Area).
BSA: Your hand= approx. 1% of 'YOUR' BSA.
Your friends hand= approx 1% of 'HIS' BSA.
