It divides the surface area of human body into 1 1 equal parts, in which the head, face and neck account for 9%, the upper limbs account for 2 9%, the front and back of trunk (13%) and perineum (1%) account for 3 9%.

Nine clinical manifestations (indicators) were first degree burn, shallow second degree burn, deep second degree burn, third degree burn, fourth degree burn, shallow degree burn, deep degree burn, moderate degree burn and severe degree burn.

First aid measures for burns:

1, thermal burn:

Take off clothes soaked by fire or boiling liquid as soon as possible, especially chemical fiber clothes, so as to avoid the continued action of hydrothermal solution on fire or clothes and deepen the wound; Put out the fire with water, or jump into a nearby pool; Roll on the spot to extinguish the fire. Standing or running on the phone is not allowed to prevent head and face burns or inhalation injuries. Leave the closed and poorly ventilated place immediately to avoid inhalation injury and suffocation.

2, chemical burns:

Rinsing with plenty of clean water for at least 30 minutes can dilute and remove residual acid and alkali, and as a way of cold therapy, it can relieve pain. Pay attention to the large amount of boiling water, which can quickly wash the residual alkali in the wound. If the head and face are severely burned, first pay attention to whether the eyes, especially the cornea, are burned and give priority to washing.

3, electric burns:

Cut off the power immediately, and don't touch the patient without cutting off the power to avoid electric shock and injury. At the same time, artificial respiration, cardiac compression and other treatments were given, and they were promptly transferred to the nearest hospital for further treatment.
