If the casualty has second-degree burns on 10 percent or less of his body surface (no third degree burns) and the situation allows, cool the area with running water.
Do not soak or immerse the effected area in water since this will promote bacteria growth.
a. Do not cool for more than 10 minutes. Prolonged cooling can result in hypothermia.
b. Do not apply cooling to third-degree burns. This could increase the risk of infection.
c. Do not apply cooling to extensive burns (over 10 percent BSA burned).
d. Do not place the casualty’s body in a tub of water. Hypothermia could result.
