This course is suitable for anyone in charge of a premises (known as the duty holder) no matter how big or small the premises and regardless of the number of people present. This includes all employers, self-employed people and anyone else in control of a premises, such as landlords and letting agents.

Landlords have an obligation to be aware of the dangers of Legionella and ensure a risk assessment is done to keep their tenants from harm. This course provides details on how to carry out a risk assessment and explains what should be included so that you have an awareness of how to identify Legionella hazards and react appropriately.

The Health and Safety Executive's ACOP L8 was written for duty holders and provides an in-depth guide to how they can comply with their legal duties. This Legionella training course is based on ACOP L8 and will cover each of the duties in more detail throughout the modules.
