Because in a third degree burn the
nerves have been damaged. If there are
no nerves, there is no pain.
3. Why do you think clothes and jewellery
near burns should be removed?
Because bacteria from the clothes and
jewellery could infect the burns.

why might you see tissue?
Because all layers of the skin have
been burnt showing the tissue
underneath.
