Occupational safety

Individual task

To complete this practice you should: apply the Risk Management Process to deal with a given variety of situations. What assumes the following steps:

• research and identify hazards;
• assess the 'level of risk' imposed by a given hazard; and
• use, modify or develop a 'hierarchy of control' to assist in the choice of control measures.

Use risk management worksheets format to record the data.
