Primary effect:
There are five degrees of burn:
1st degree: outer skin only
2nd degree: to inner layer of outer skin
3rd degree: to inner layer of inner skin
4th degree: to deepest hypodermic layer
5th degree: to muscle
Burn victims of napalm do not experience 1st degree burns due to the adhesive properties of napalm that stick to the skin. 85% of burn victims experience 4th or 5th degree burns. The pain is so excruciating that people have died from the pain alone.
Two thirds of victims have burns covering 25% of their body. If a body has burns covering 50% of their body and 20% of the burns are 4th or 5th degree burns then death is almost certain. Victims who recover from 4th or 5th degree burns develop hideous scars called keloids which also bring about motor disturbances.
Secondary effects:
A large amount of carbon monoxide is produced once a napalm bomb is set off. It makes it very hard for people to breath which causes them to pass out and burn. Carbon monoxide poisoning itself can be serious. Disturbances of the nervous system, insomnia, weakness and low temperature are common symptoms.
Napalm victims also suffer from burned windpipes and shock. Bones can alter themselves and sometimes blood and internal organs are affected.
