A burn is damage to the skin or underlying tissue caused by heat. There are 3 levels of severity; 1st, 2nd, 3rd.
There are 5 main sources of burns; electricity, radiation (sun), thermal (something hot), chemical, and friction.
1st degree: red, swollen, pain
2nd degree: red, swollen, blisters
3rd degree: damaged skin to the point where the underlying tissue is visible
For 1st and 2nd degree burns you should cool the area immediately with gently running cold water for about 10-15 minutes, or until it has cooled off. Do not break any blisters as this will make the wound worse
For 3rd degree burns do not put anything on the burn, seek medical help immediately and treat for shock. 3rd degree is extremely life threatening even when a small body part is effected. If there is clothing on the burn do not remove it as this may also remove skin. There is a very high risk of infection from this kind of burn
As with all other emergencies make sure the area is safe for you first. Watch out for live wires, hot objects, chemical spills, etc
The severity of a burn can also be increased pending on the sensitivity of the body part that is burnt, or the amount of the body that is burnt
With electrical burns check for an exit wound as well as treating for the entrance wound
With chemical burns flush the area with lots of water to get it off the casualty’s skin
Never apply ointments, butter, or other home remedies on burns, as this may make the burn worse, keep the heat trapped in, or cause an infection
