Risk Assessment

Under the Control of Substances Hazardous to Health (COSHH) Regulation and operators of all commercial premises, including Hotels, Schools, Hospitals, Care Homes, Social Housing, Offices and Leisure Facilities etc. have a statutory duty to control the risk of legionella bacteria in water systems.

Where there is a risk and there are 5 or more employees the assessment should be formal recorded - this document is The Legionella Risk Assessment

You are required to

  • Identify and assess the sources of risk
  • Prepare a scheme for preventing or controlling the risk - The SafeWater programme
  • Appoint a person to be managerially responsible
  • Implement and manage precautions
  • Keep records of the precautions implemented

As set out in the HSE ACOP L8 guidance, The Control of legionella bacteria in water systems, the person on who the statutory duty falls is required to have \\\'access to competent help in assessing the risks of exposure to. This involves the appointment of an external water expert to produce a risk assessment.

The ACOP L8 regulations indicate that an appropriate risk assessment is the first step in Legionnaires’ disease prevention. 

The purpose is to identify all water systems where legionella bacteria could possibly grow and assess the risk of people being exposed to contaminated aerosols from them.

 All water systems need to be included in the legionella risk assessment.The most common places where legionella can be found include purpose-built water systems, cooling towers, evaporative condensers, hot and cold water systems and spa pools. 

There are also a number of other systems that may pose a risk to exposure to legionella, e.g. humidifiers, air washers, emergency showers, indoor ornamental fountains etc.

  • HydroChem Risk Assessments

    HydroChem UK Ltd, are a Category 1 Legionella Control Association registered company.

    A HydroChem, professional Legionella Risk Assessment, identifies the level of risk within your property, which is the first step of any water hygiene control programme, to give you L8 compliance

    Which includes:

    • Initial Assessment
    • Water System Schematic Diagram(s)
    • Recommendations for Remedial Works to minimise legionella risk
    • Recommendations for on-going water Hygiene monitoring in accordance with L8
    • Comprehensive Log Book for record keeping
    • Microbiological Reports of any water tests - if applicable
    • Treatment Records and Certification - if applicable

    Where the risk assessment highlights a foreseeable risk of exposure to bacteria, it is then necessary to implement control measures to reduce the risk brought to light within the Risk Assessment. This usually takes the form of a Legionella Monitoring program and would include the following;

    • Weekly flushing of infrequently used services
    • Monthly temperature monitoring
    • Quarterly de scaling and disinfection of shower head
    • Six monthly tank inspections
    • Annual review
    • Awareness training
    • Tank cleaning and disinfection as required
