Chapter 18: Biological Hazards
Biological hazards present the Occupational Health and Safety (OHS) professional with complex challenges. Many and varied biological hazards may result from workplace exposure to organisms, or substances produced by organisms, that threaten human health. Although workers in health and community care, and agricultural and fishing occupations are at particular risk of exposure to hazardous biological agents, all workplaces harbour the potential for various forms of biological hazard exposure, particularly via person-to-person transmission of infectious disease. The COVID-19 pandemic has brought a heightened perspective to the management of biological hazards and the role of the OHS professional. This chapter outlines the knowledge required by the OHS professional to understand the nature of biological hazards and the principles of control. Armed with this knowledge, the generalist OHS professional can then facilitate a team approach to the identification, assessment and control and mitigation of biological hazards.

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 an OHS professional; it 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 .
Please read the section on using the learning outcomes before delving into the leaning outcomes of the individual chapters.
The numbers against each learning outcome refer to the chapter number of the BOK download page. No learning outcomes have been developed for the chapters considered introductory or underpinning knowledge (that is chapters 1, 2, 3, 4, 5, 6, 7, 1, .13, 14, 15.)
AIHS Webinar: Biological Safety
Dr. Amanda Jones
This webinar discusses the basics of biosafety and why biological risk management is important. It looks at some obvious and not so obvious situations where biosafety needs to be considered and some key ways to manage biosafety that all safety professionals and practitioners can employ.
