Chapter 31.2: OHS Risk and Decision Making
Risk management is part of organisational decision-making with poor decision-making about risk being a factor in workplace fatality, injury, disease and ill-health. Generalist Occupational Health and Safety (OHS) professionals can influence decision-makers to make informed choices about risk. To do so they need to understand the nature of risk and its inherent uncertainty and how decisions are made in organisations and by individuals, and the factors influencing such decisions. This chapter examines decision-making theory, types of organisational decisions and factors influencing decisions about risk. It considers risk communication, legal and ethical issues, and the limitations of risk assessments. The chapter concludes with an examination of the role of the OHS professional in influencing risk-based decision-making, and presentation of a model to inform OHS professional practice.

Consulting Risk Engineer
Derek is a consulting risk engineer and management consultant in risk control who has been instrumental in developing the academic disciplines of accident phenomenology and risk philosophy through his continuous involvement in post graduate in risk and safety.
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
SWA Videos - Effective work health and safety risk management
In this video Derek talks about the need to both identify risks and maintain a risk inventory to track them long-term. He also discusses managing risks using a hazard management plan, understanding levels of control, and the need for different approaches to managing general and operational risks.
