Delivery Method

Online E-Learning
Learners can complete the course remotely at a time that suits them.
The course is designed to provide concise, practical Legionella awareness without requiring learners to attend a classroom-based programme.

The course can introduce learners to the Irish legal and regulatory framework relevant to workplace Legionella and biological agent risks, including:

• Safety, Health and Welfare at Work Act 2005
• Safety, Health and Welfare at Work (Biological Agents) Regulations 2013, as amended
• Safety, Health and Welfare at Work (General Application) Regulations 2007, as amended
• Relevant Health and Safety Authority guidance concerning Legionella and workplace water systems

The Biological Agents Regulations require employers, where employees are or are likely to be exposed to biological agents through work activities, to assess risks and provide appropriate information and training where required.

The HSA specifically advises employers and persons in control of workplaces to consider Legionella risks, identify potential sources, assess who may be harmed, implement appropriate controls and maintain an effective Legionella control plan.

This e-learning course is an awareness programme and does not replace a site-specific Legionella risk assessment, competent-person assessment, water hygiene management programme, or specialist Legionella control services where these are required.
