CAN - Covid-19 prevention and the hierarchy of controls

Selecting an appropriate method to control a hazard in the workplace is not always easy. When it comes to the transmission of viruses such as COVID-19, workplaces should consider establishing control measures that have the greatest impact.

The main ways to control a hazard, from the most to the least effective, include elimination (and substitution), engineering controls, administrative controls, and personal protective equipment (PPE). In all cases, physical distancing, hand hygiene, and respiratory etiquette should be practised.

See an infographic on how the hierarchy of controls can be applied to COVID-19 in the workplace, including examples of controls for each level.
