Well, as long as someone's asking:
The severity of a burn can be described by degrees:
1st degree - limited to the most superficial layers of the skin, producing redness and pain, as in a scald or moderate sunburn.
2nd degree - penetrates the skin deeper, producing pain and blistering, as well as some subcutaneous swelling. Blister formation may not be apparent until several hours after the injury; before the blisters become visible, the skin may simply be red and mottled. Severe pain is characteristic of these burns because nerve endings are irritated and hypersensitive; the slightest pressure or other stimulation of the burned area causes exquisite pain. Second degree burns are most commonly caused by contact with boiling liquids.
3rd degree - involves damage to or destruction of the full thickness of the skin and can involve underlying muscle, bone (military definition of '4th degree'), and other structures as well. The skin in a third degree burn may appear charred and leathery or may be dry and pale. Pain is usually absent because of destruction of nerve endings. Patients with third-degree burns are prone to lose massive quantities of fluid; since they lack the usual protective mechanism of the skin. Massive infections are not uncommon.
If a person sustains a third-degree burn, there is usually an expanding ring of burns of lesser severity surrounding it.
I know, I know ...
ObTasteless:
Received a call for 'woman with burns.' Arrived at an elderly housing complex, where the fire department was already on-scene, and was hurrying us up the stairs to the woman's apartment. The smell of burning plastic and hair wafted through the hallway as we reached her door. Entered the apartment to find - what else - an elderly woman in some sort of polyester night-gown, sitting in an easy-chair. Apparently, she had been in her bedroom, and had fallen asleep while smoking a cigarette. The cigarette had dropped on her night-gown, which promptly burst into flame. She awoke to find herself on fire, got out of bed, walked to her easy-chair, sat down and dialed the fire department. Her night-gown had melted over her body, leaving large black patches of plastic molded to her skin, which cracked every time she shifted in the chair - much to the consternation of the firefighters. Patches of her hair were singed, the smell of which was overpowering. Initially, the fire department had thought that she'd fallen asleep in the chair, but revised their estimate once someone pointed out the black, melted foot-prints in the carpet leading from the bedroom to the chair, and the bits of melted flesh that trailed the footprints. By the time we lifted her out of the chair to place her on the stretcher, the burning plastic that had melted onto her back had had time to cool and mold itself to the chair. The result was that a large portion of the skin on her back remained with the plastic - on the chair. Her back now looked like oozy, grey leather - if you could picture that.
In the ambulance, I tried to start an IV, which was hard, since both her arms had received burns. I applied a tourniquet to her arm, and tried to clean her forearm with an alcohol swab, only to watch as the entire top layer of her skin roll off - like a glove, with only gentle rubbing.
This gal was fucked.
A helicopter had been requested to airlift her to Boston. Our unit arrived at the LZ, and the flight crew jumped in the back of our ambulance. The flight nurse must have been new, since she took one sniff and started retching.
Of course, the woman died.

That's because liquids - especially thick, viscous ones, stick to the patient, allowing more heat transfer and damage to occur than a simple 'flash' burn. Steam injuries of the same temperature are even worse, since there is additional heat transfer from the steam going from a gas phase to a liquid phase - which results in a double-whammy. Not to mention when the airway is involved, such as a car radiator explosion. People usually have a sharp intake of breath when surprised - and take in some superheated steam from the radiator. The swelling of the airway takes place some time later, and their windpipe closes completely, necessitating a tracheotomy - messy.
