Highfield Level 2 Award in Legionella Awareness (RQF) 13 Unit 3: Understanding the risks associated with legionella in hot and cold-water systems Unit number: D/506/1505 Credit: 1 GLH: 4 Level: 2 Learning Outcomes Assessment Criteria The learner will The learner can 1. Understand the risks associated with legionella bacteria in hot and cold-water systems 1.1 Outline how hot and cold-water systems operate 1.2 Describe the factors that contribute to the risk of legionella bacteria within hot and cold-water systems 2. Know how to control the risks associated with legionella bacteria in hot and cold-water systems 2.1 Explain the requirement for routine monitoring 2.2 Describe the requirements for routine checks of the system 2.3 State the requirement for carrying out legionella testing 2.4 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 hot and cold-water systems • How hot and cold-water systems operate: o The basic components of a hot and cold-water system o Why their design and method of operation can cause systems to present a risk • The factors that contribute to the risk within hot and cold-water systems: o Why systems pose a risk, including: ▪ Generation of aerosols ▪ Stagnant conditions ▪ Low use of systems ▪ Temperature of operation ▪ Nutrients ▪ Biofilm o How removing parts of the system and controlling the operation of the system can be used to minimise and control the risk factors LO2: Know how to control the risk of legionella bacteria in hot and cold-water systems • The requirement for routine monitoring: o How monitoring and checks contribute towards controlling the risk factors within a system
