A competent Legionella risk assessment is essential for making sure water systems are not putting occupants at risk of Legionnaires’ Disease.
A legionella risk assessment is a legal requirement in buildings with a high footfall of people such as hospitals, schools and commercial properties. This is part of the compliance criteria for ACoP L8 (Approved Code of Practice L8 2013 – (The Control of Legionella Bacteria in Water Systems). HSG274 also contains guidance for Legionella control.
Cooling towers and HVAC systems are key risk areas for Legionella growth, but all sanitation and general plumbing should be checked as the bacteria can grow in any location where water is present.
Building owners, landlords, employers, building and facilities managers are all responsible parties. A water treatment company such as Guardian can undertake any work following a risk asssessment.
Expert legionella risk assessment support will ensure this important work is done correctly. All of our legionella risk assessors are competent and experienced engineers, able to quickly identify the conditions that could lead to an outbreak of Legionnaires Disease.
You or the person responsible for managing risks needs a good understanding of the water systems and associated equipment, such as pumps, heat exchangers and showers.
Some water systems are more likely to be at risk of legionella than others, such as:
Any Legionella issues flagged by the risk assessment must be dealt with by a competent person – i.e. someone with sufficient authority, skill and knowledge of your water system to deal with the problem.
Someone within your business must take this responsibility. Where necessary, they can employ outside support to mitigate the risks posed. Make sure the external water treatment company and/or contractors you choose meet industry standards.
