Controlling risk to prevent work-related fatalities, injuries, diseases and ill-health is the core role of the safety professional. Legislation governs the duty to control workplace risk and looks for organisations to do more than just compliance activities.

A chapter published by the Australian Institute of Health and Safety explores the underpinning principles of controlling risk. The law does not require a risk-free work environment where accidents never happen, but instead requires employers to take such steps as are practicable to provide and maintain a safe working environment. The safety professional must consider controlling risk to decrease the probability or likelihood that hazards become uncontrolled and they need to mitigate the effects of the consequences of risks. Several principles underpin the strategies for controlling risk.

This podcast summarises requisite variety, the hierarchy of controls, time-sequence approaches, barriers and defences, the precautionary principle and the socio-technical systems approach to controlling risk. We also offer control strategies that health and safety professionals can use.
