Management of Legionella Bacteria in Hot and Cold Water Systems training course

A 2 day training course designed to improve knowledge concerning control of legionella in hot and cold water systems; ideal for learners wishing to get more heavily involved in the subject. This course is heavily focused around the HSE’s technical guidance document HSG 274 Part 2. It aims to increase knowledge and allow more informed decision making concerning multiple factors such as configuration, turnover, temperature control etc.

N.B. Learners wishing to attend this course should have some industry experience or have been introduced to the subject matter prior (for example, by undertaking our WS11 course – Legionella Awareness and ACOP L8).
