Legionella risk observation checker
Answer a few questions to see red flags and next steps. This is a quick check, not a risk assessment.

Educational observation aid based on HSE duties, not a risk assessment, risk rating or legal advice. Source: HSE, what you must do; ACoP L8 (2013), “Carrying out a risk assessment”, p.12.
