Examples of work that would have a higher risk include working in confined spaces, working with chemicals, working with heights etc.

Code of Practice: A detailed list of procedures for workers to follow while performing their duties. The Code of Practice may be relatively basic or extremely comprehensive depending on the complexity of the work performed.
