|Superficial burn||Ultraviolet light,very short flash (flame exposure)||Dry and red; blanches with pressure||Painful||3 to 6 days||None|
|Superficial partial thickness burn||Scald (spill or splash),short flash||Blisters; moist,red and weeping; blanches with pressure||Painful to air and temperature||7 to 20 days||Unusual; potential pigmentarychanges|
|Deep partial thickness burn||Scald (spill), flame, oil, grease||Blisters (easily unroofed); wet or waxy dry; variable color (patchy to cheesy white to red); does not blanch with pressure||Perceptive of pressure only||More than 21 days||Severe (hypertrophic) risk of contracture|
|Full thickness||Scald (immersion), flame, steam, oil, grease, chemical, high-voltage electricity||Waxy white to leathery gray to charred and black; dry and inelastic;does not blanch with pressure||Deep pressure only||Never (if the burn affects more than 2 percent of the total surface area of the body)||Very severe risk of contrac ture|
|Type of burn||Minor||Moderate||Major|
