The presence of legionella in water systems poses significant health and safety risks and an understanding of the regulations of legionella in Scotland and proactive measures are required to mitigate these risks. Combining insights from recent outbreaks and legislative frameworks, this article aims to guide landlords and individuals towards ensuring compliance and safeguarding public health. 

What is Legionella?๐Ÿ’ง

Legionella is a bacteria known for transmitting legionnairesโ€™ disease which is a severe form of pneumonia. Everyone is susceptible although certain groups such as heavy smokers or drinkers and individuals over 45 are more vulnerable. The bacteria can be found in freshwater sources and can enter domestic water systems including taps, showerheads, hosepipes and hot tubs.

Legionella in Scotland – Recent outbreaks

Recently legionella has been making headlines, with notable cases in Scotland. The Royal Alexandra Hospital in Paisley reported a presence of legionella in July 2023. The hospital announced the removal of patients from two wards after testing revealed that legionella was present in six water outlets.

In August 2023, legionella was found at Edinburgh’s Western General hospital. Legionella was found in the water supply of a cancer treatment ward. A thorough programme of disinfection and cleaning was undertaken at the hospital.

Futhermore, Public Health Scotland published an updated report on legionnaires disease which indicated a rise in cases in 2022. Attributing factors include changes in testing policies, water system maintenance and weather patterns. 

Legionella in Scotland – Regulations and Compliance โš–๏ธ

Legionella regulations in Scotland are rooted in the fundamental health and safety legislation. Most notably the Health and Safety at Work Act 1974 and the Control of Substances Hazardous to Health Regulations 2002. Landlords bear a legal obligation to ensure the well-being and health and safety of tenants in rental properties.

Employers and landlords are entrusted with the responsibility of managing health and safety risks associated with legionella. Failure to comply with these regulations can result in substantial fines. The legal framework underscores the significance of a proactive approach to legionella testing and risk assessment, emphasizing a duty of care to safeguard the health and well-being of occupants. 

A Vital Measure for Safety ๐Ÿ“

Conducting a Legionella Risk Assessment (LRA) is a fundamental step in safeguarding homes and buildings. The systematic evaluation of water systems aims to identify potential sources of legionella bacteria. Water temperature, the presence of biofilm and infrequently used parts are key factors. Regular assessments are crucial to mitigate the risk of legionella exposure. 

To reduce the risk effectively, initiating a LRA is paramount. They are crucial for ensuring the safety of domestic properties and especially if water systems have been dormant. Encouraging assessments in domestic settings underscores the proactive approach needed to maintain a safe environment and prevent potential legionella-related issues.  

Using a Certified Assessor โœ…

Landlords can undertake assessments themselves although, outsourcing to a legionella risk assessor offers numerous benefits. These professionals possess in-depth knowledge of legionella bacteria, conditions promoting growth, and tailored recommendations based on specific water systems. Their expertise ensures an independant thorough assessment and effective risk management.
