Flame burns are often deep burns, causing partial- to full-thickness burns.

Hot liquid burns are not as deep as flame burns, but they can still produce deep burns. Examples of hot liquids which can cause burns include hot water, coffee, grease and hot soup.

Burns from touching hot objects vary in depth, since people’s reflexes cause them to react quickly. These burns can be caused by touching a stove, skillet or grill.

Flash injuries are burns that involve exposed parts of the skin and vary in depth depending on the proximity on the flash and the intensity. Automobile, gas tank and airplane explosions are causes of flash burns.

Sunburns can be extremely painful, but the pain is relieved as the wound is soothed and injury progression is stopped. Sunburns are usually superficial burns or first-degree burns.
