* If possible, '''leave blisters intact'''. Damage to a blister increases the risk that the burn will become infected.
=== Cuts ===
* '''Avoid major blood vessels'''. Arteries carry blood at high pressure from the heart: if you puncture one, this will cause life - threatening bleeding. Punctured veins can also lead to heavy blood loss.
** It’s safest to cut the '''fleshy parts of the body''', e.g. the outer arms, the outer thighs, or the calves.
* Try to use '''straight-edged blades'''. Injuries with jagged or serrated edges will heal more slowly and be more prone to infection.
