Classification of burns
Burns can be classified by their type and depth.
Types of burn
Scald – caused by a hot liquid
Friction – caused by rough surfaces, e.g: carpet
Electrical – will have an entry burn and an exit burn
- Dry – touching hot objects, e.g: a cooker.
Depths of burn
Superficial (1st degree) – this is when only the top layer of skin has been damaged. These are the most minor burns. Often the only sign is a reddening of the skin. Minor sunburn falls into this category of burns.
Partial thickness (2nd degree) – these burns cause blisters in the skin due to the damaged tissue releasing fluid.
Full thickness (3rd degree) – this is the most serious type of burn. In a full thickness burn, every layer of the skin has been affected and the underlying bone, muscle or fat may have also been damaged.
