Chapter 34.1: Control: Prevention and Intervention
Abstract
Hazard and risk control to prevent work-related fatality, injury, disease and ill health is the core objective of the OHS professional. While there is a legislative requirement to control risks in the workplace, the approach should go beyond mere compliance. Control of hazards and risk is not necessarily an easy or straightforward task. While the methods of controlling individual hazards such as chemicals and noise are well understood, there are many workplace injuries and disorders that have multiple causes, and there are different approaches to control. This chapter addresses key principles of control, including hierarchies of control, time-sequence approaches, requisite variety, barriers and defences, the precautionary principle and the sociotechnical systems approach. A brief discussion of two control strategies – safe design and behavioural-based safety – is followed by consideration of the implications for OHS practice. The chapter emphasises the role of the OHS professional as an organisational change agent, rather than just a risk-management technician.

Learning Outcomes: Control: Prevention and Intervention
The OHS Body of Knowledge takes a conceptual approach which enables it to be applied in different contexts and frameworks. To optimise its value for education and professional development learning outcomes have been developed for each technical chapter in the Body of Knowledge.
The learning outcomes as described give an indication of what should be the capabilities of a new graduate OHS professional in the workplace. I t is up to those developing OHS education programs, OHS professionals planning their CPD or recruiters or employers selecting or developing people for the OHS function to consider the required breadth vs. depth
