At AJK Services we understand the potential dangers of Legionella and why it is so important that businesses and landlords comply with the necessary Legionella control regulations under the Health and Safety at Work Act 1974
What Is Legionella?
Legionella is a hazardous bacterium which can be found in natural water sources such as rivers, lakes and ponds. Legionella can also be found in manmade water systems and become hazardous to human health. The bacteria itself requires 3 things within a water system for it to thrive:
- Temperature
Below 20°C Legionella will remain dormant, it is still present but is not able to grow or spread. Temperatures above 50°C will kill the bacteria completely within about 2 hours. Temperatures above 60°C will kill the bacteria completely within about 2 minutes.
- Nutrients
As all living things require a source of food or nutrients in order to thrive, so does Legionella. It relies on materials such as scale, rust, sludge and Biofilms (collectives of microorganisms) to support its growth.
- Stagnation
Infrequently used outlets or areas of redundant pipework can create the perfect environment for Legionella by supporting loss of temperature, settlement of particulates in the water system such as scale, rust and sludge as well as Biofilms (collectives of microorganisms).
A Legionella risk assessment is used to help identify potential risk factors within buildings, premises and facilities. The findings are then used to pinpoint what interventions are required and the protocols and systems that need putting in place in order to establish robust Legionella risk controls.
Is a Legionella Risk Assessment a Legal Requirement?
Under UK Health and Safety law – landlords, business owners, employers and property managers are legally required to assess, mitigate and consider the risk of Legionella within their business or property.
What Does a Legionella Risk Assessment consist of?
A Legionella risk assessment is the first step to help ensure a Legionella compliant property for its occupants and for those responsible to prove they have taken the necessary steps needed to keep people safe.
At AJK Services our Legionella Risk Assessments include:
- Introduction and background information on Legionella
- Site details
- Legionella Management Documentation audit
- Condition survey reports of domestic & commercial water plant
- Temperature profiling
- Photographic evidence
- Asset register
- Identification of risks – this includes but is not limited to, dead leg pipework (if visually observed on exposed pipework) and little used outlets
- Recommendations for future legionella control and management
- Basic schematic of plant and distribution
At AJK Services, we understand the requirements of a Legionella risk assessment and regularly aid companies with the Legionella assessment process to ensure an effective management tool is in place to help control risk and monitor conditions within their water system.
As one of the leading Legionella assessment companies in the UK, we can help your business by identifying the factors which increase risk, so that you can see where you need to prioritise actions and what you need to do in order for your business to comply with the Legionella control regulations.
