Remember to first "Stop, Drop and Roll" to extinguish the flames and then "remove, cool, cover and seek"
Always make sure you are safe first before you touch the patient! Turn off the electricity using a wooden object or the safety switch so that you do not get electrocuted or burned too. Then "remove, cool, cover and seek".
Use a cloth to brush off any chemicals on the skin, do not use your bare hands. Then "remove, cool, cover and seek".
If the sunburn is extensive, have a cool shower, otherwise flush the area with cold water for 20 minutes. If the sunburn covers a large area, is in delicate areas or the patient feels unwell or sick, seek medical attention.
