About this course
Legionnaires’ disease is a potentially fatal form of pneumonia caused by inhaling small droplets of water contaminated with Legionella bacteria. Risks may arise wherever water is stored or recirculated and where aerosols can be produced.
Employers, landlords and those responsible for premises have legal duties to identify, assess and control the risk of exposure to Legionella. This includes maintaining appropriate records and appointing competent people to help manage the necessary precautions. HSE guidance for dutyholders
This practical one-day course introduces delegates to the causes of Legionella growth and the types of water systems that may present a risk. These include hot and cold water services, showers, cooling systems, spa pools, humidifiers, emergency showers and other equipment capable of producing water droplets.
Delegates will learn how poor temperature control, stagnation, dead legs, infrequently used outlets, scale, sludge, corrosion and inadequate maintenance can increase risk. The course also explains how suitable control schemes, regular monitoring, flushing, cleaning, temperature checks and accurate records help maintain safe water systems.
The training reflects the principles of the HSE’s Approved Code of Practice L8 and technical guidance HSG274. HSG274 provides detailed guidance covering evaporative cooling systems, hot and cold water systems and other risk systems.
