Understand the risks associated with legionella bacteria in cooling towers and evaporative condensers 1.1 Outline how cooling towers and evaporative condensers operate 1.2 Describe the factors that contribute to the risk of legionella bacteria within cooling towers and evaporative condensers 2. Know how to control the risks associated with legionella bacteria in cooling towers and evaporative condensers 2.1 Explain the requirement for routine monitoring 2.2 Describe the requirements for routine chemical testing 2.3 Describe the requirements for routine physical checks 2.4 State the requirement for carrying out legionella testing 2.5 Explain the requirements for cleaning and disinfection Amplification This section of the specification expands on the assessment criteria defined in the above unit and includes suggested content that a training course should cover in order to adequately prepare learners for the assessment. LO1: Understand the risks associated with legionella bacteria in cooling towers and evaporative condensers • How cooling towers and evaporative condensers operate: o How a tower/condenser uses the process of evaporation to work o The individual parts of tower/condenser and their purpose • The factors that contribute to the risk within cooling towers and evaporative condensers: o Why a tower/condenser poses a risk: ▪ Generation of aerosols ▪ Distribution of aerosols ▪ Temperature ▪ Nutrients ▪ Contamination ▪ Biofilm
