Clearwater Technology A comprehensive assessment should
include the inspection of obsolete pipework (known as ‘dead legs’ or ‘dead-ends’) such as piping to unused taps where water can stagnate and encourage the growth of Legionella bacteria. Remedial action should then take place to remove any dead legs from the water system, eliminating the opportunity for water to stagnate and create a risk. Flexible hoses are commonly lined with
a material called EPDM (ethylene propylene diene monomer). This material can encourage the growth of Legionella bacteria. While hoses constructed with EPDM are banned in healthcare environments, they can often be found in water systems in other sectors. As remedial action, these can be replaced by non-EPDM hoses or solid copper fittings. Major assets must also be inspected. From
cold storage tanks to calorifiers (hot water heaters) and cooling towers, major assets must be inspected for scale, corrosion and sediment which are all warning signs that Legionella bacteria may be present in the system. Remedial action to remove risk can include the cleaning and disinfection of these major assets. A Legionella risk assessment must also
include a schematic drawing of the building’s water systems and temperature profile of both the assets and outlets.
FSM 13 Textbook Management
Legionella risk assessments must be carried out by a competent individual who is confident that they have a full understanding of the relevant codes of practice. While your building or facility management might make every effort to ensure full safety and compliance, assigning the responsibility to an under-qualified individual can result in non- compliance and an un-safe water system. In many cases, building and facility
managers will outsource the responsibility of risk assessment and remedial action to an experienced water treatment provider. When searching for an experienced provider
it’s important to ensure you’re being offered more than a one-size-fits-all solution and that the provider can instead tailor a bespoke risk assessment and risk management solution to your specific business and its individual requirements. Each building or facility will have its own
site-specific risks and it’s essential that your water treatment provider recognises these risks and builds a programme around them. By utilising the expertise of qualified and experienced risk assessment experts, buildings and facilities across the UK can take control over the growing risk of Legionella in their water systems.
