How are people most likely to get burnt
Most people are likely to get burnt at home: by knocking over a glass of hot water, by picking up a hot pan, or by getting cooking oil spilt on themselves.
Discussion
What steps can be taken to help prevent
these burns
Being aware of the danger is a good first step.
For example, you should check to see if the
burner is on before touching a pan on the stove.
If you are using cooking oil, you should make
sure that the pot is set firmly on the stove so that
it cannot spill, and that it is not too full of oil.
Prevention is better than cure.
