FIRST AID FOR SCALDS
1. Remove all wet clothing quickly. Wet clothing retains the heat.
2. Apply cold water to burned area for 30 minutes to reduce the heat in the skin and prevent deeper
burning. Never use butter, oils, or ointment to cover the burn. They may retain the heat.
3. Use a blanket to keep the scalded person warm.
4. Seek medical advice.
