Legionella Risk Assessments for Workplaces
Keeping an office safe means looking after the people who use it every day. Legionella bacteria can grow in poorly managed water systems and cause Legionnaires' disease, a serious form of pneumonia. Both small offices and large workplaces need to consider the potential risks linked to their water systems.
At Summit Environmental, we provide professional legionella risk assessments for offices across the South East. Our assessments help employers and building managers understand the risks within their water systems and put suitable control measures in place.
Why Offices Need a Legionella Risk Assessment
Office buildings can contain several areas where legionella bacteria may grow. The risk can vary depending on the size of the building, how often water systems are used and how they are maintained.
Some common factors include:
- Water temperature: Legionella bacteria thrives in water that is stored at temperatures which allow it to multiply. Keeping water at suitable temperatures is an important part of legionella control.
- Hot and cold water systems: Taps, showers, storage tanks and other outlets can all form part of the assessment.
- Infrequently used outlets: Taps or facilities in unused areas can allow water to stagnate.
- Complex systems: Some offices may have larger pipework systems and multiple water outlets, making it harder to monitor every part.
- Changes in building use: Empty offices, refurbishment work or changes to occupancy can affect how water systems are used and managed.
