Who should take this course?

This course is suitable for anyone in charge of premises (known as the duty holder) with water systems that could pose legionella risks, no matter how big or small the premises are, 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. It will explain what their legal duties are in relation to the water systems in their premises, how to carry out a risk assessment for legionella, and what control measures they may need to implement.

Examples of man-made water systems that duty holders may have in their premises include:

  • Evaporative cooling systems.
  • Dry and wet coolers or condensers.
  • Hot and cold water systems, such as for taps and showers.
  • Spa pools.
  • Misting devices for food production.
  • Emergency showers and face wash fountains.
  • Sprinkler and hose reels.
  • Vehicle washes including automatic washers.
  • Wet scrubbers and gas scrubbers.
  • Fountains and decorative water features.

The Health and Safety Executive's ACOP L8 provides an in-depth guide to how duty holders can comply with their legal duties. This training course is based on ACOP L8 and will cover each of the duties in more detail throughout the modules. It has also been written with consideration of the three HSG 274 documents that provide further guidance for specific man-made water systems, as well as the guidance document for spa pools. It is also suitable for landlords, who have an obligation to be aware of the dangers posed by legionella bacteria and to carry out a risk assessment, so they can keep their tenants safe from harm.

Taking this course will therefore help duty holders understand what to do to follow the guidance set out in ACOP L8 and where to find further advice for their specific water systems.

COVID-19 and Legionella

This course is suitable for duty holders looking to carry out a legionella risk assessment after their business has experienced a period of closure due to COVID-19. It explains the HSE guidance set out specifically for COVID-19 risks that arise due to closures. Water systems in buildings that are unoccupied for prolonged periods of time may be at risk of water stagnating in the system and legionella bacteria growing, so it is important for you to consider this risk if your workplace closes for any period of time due to COVID-19.
