Emergency medical technicians use this method to quickly assess the extent of burns for someone 14 years or older. The body is divided into sections. Each section is given a percentage value that is either nine percent or a multiple of nine percent.
Arm and Hand – 9 Percent Each
Back of the Body – 18 Percent
Front of the Body – 18 Percent
Genitalia – 1 Percent
Head and Neck – 9 Percent
Legs and Feet – 18 Percent Each
An example would be if someone had one arm and the back of the body burned, a fair estimate would be 27 percent. Knowing this number helps medical professionals determine the best course of treatment.
