Legionella Awareness – Refresher

Legionella Awareness – Refresher

ETD’s Legionella Awareness Course Refresher will explain the principles of Legionella control so you can minimise infection. Legionella is a highly dangerous bacteria, and one in eight people infected with Legionnaire’s disease dies. 

But, with the right training, we can get this number down. If you took the Legionella Awareness Course three or more years ago, you’re ready to take the refresher course. In this training, you’ll review how Legionella bacteria spreads, how to control the spread of this bacteria and how to put measures in place to keep everyone in your workplace safe. This recap training will guide you through the following.

Medical Aspects and the Nature of the Bacteria

  • Legionnaires’ disease
  • Pontiac fever

Record Keeping and Risk Assessments

  • What to include in records
  • What risk assessments should address
  • Sources of the risk
  • How to avoid proliferation
  • Risk assessment checklists

Protection of Personnel

  • Cleaning methods
  • Respiratory protective equipment
  • Protection from falls

Test & Certification

Warm aerosol producing systems such as shower heads, hot tubs, spa baths and water cooling or heating systems are breeding grounds for the Legionella bacteria, and many people contract Legionnaire’s disease from these sources. Legionella bacteria thrive at 35°C, meaning it spreads quickly in warm environments such as those listed above, putting everyone in the vicinity at risk. If you work in an environment with any of these systems, we highly recommend taking the Legionella Awareness Course and refresher training.

At the end of the online abrasive wheels training, you will be given a 20-question, multiple-choice test. The required pass rate is 85%. You will be able to download and print a digital certificate on completion of the course. A course certificate is 12 months for this annual refresher.


The course will take approximately 17 minutes to complete, excluding the final exam.
