Chapter 15: Hazard as a concept

Chapter 15: Hazard as a concept

Abstract
In occupational health and safety (OHS), the term ‘hazard’ is defined and used in many different ways. In introducing a series of hazard-specific chapters in the OHS Body of Knowledge, this chapter considers some of the issues associated with these various definitions and applications, including, for example, the common misidentification of failures of controls as hazards and equating hazard with risk. This chapter discusses a range of definitions and classification systems for hazards and proposes that while different definitions and classification systems may be useful depending on the context of the OHS activity; extended discussion on the topic is advocated. This discussion needs to acknowledge that multiple hazards may be present in many situations, and that workplaces are inherently complex systems. While different definitions and classifications of hazards may be tailored to different contexts and purposes, the chapter concludes that the fundamental test as to whether something is a hazard is that if it is eliminated there is no risk.
