how do i create a outline of the risk of using Malathion according to the four steps fo risk assessment presented in Chapter 4, page 73, figure 4.1

Since we do not have access to the figure, it is very difficult to provide help. You might use the Roman numerals I-IV for the four steps and start from there. Qualities or substeps can be listed with letters -- A, B, C and so on -- under each of those four steps.

I hope this helps. Thanks for asking.
