Table 2. Depth categories for burn injuries and guidelines for the categories as presented in the application manual.

1.	Superficial Thickness Burns
	This is similar to sunburn and is the mildest form of burn. There may be blistering. These burn areas are not included in fluid calculations, but should be recorded for the clinical notes.
2.	Partial Thickness Burns
	These burns affect the epidermal layer and usually present as painful, reddened and sometimes blistered areas on the body.
3.	Full Thickness Burns
	These burns have burned beyond the dermis and are unable to heal themselves. They are usually white/grey and feel leathery to the touch. These burns require a skin graft.
4.	Indeterminate Depth Burns
	These burns are difficult to assess at the time of injury and lie between superficial and full thickness burns. Time is needed to see if these burns progress to full thickness or remain superficial and heal spontaneously.
