Domestic hot and cold water systems are the second most common cause of cases of Legionnaires disease after cooling towers and evaporative condensers. Hot and cold water systems of any size can become colonised.
Duties under the Health and Safety at Work Act 1974 (HSWA) extend to risks from Legionella bacteria, which may arise from work activities.
The Management of Health and Safety at Work Regulations (MHSWR) provide a broad framework for controlling health and safety at work.
The Control of Substances Hazardous to Health Regulations 2002 (COSHH) provide a framework of actions designed to assess, prevent or control the risk from biological agents such as bacteria like Legionella and take suitable precautions.
The Approved Code of Practice and Guidance L8 applies to plant and systems containing water that is likely to exceed 20℃ and which may present a risk by releasing a spray or aerosol during operation or when being maintained.
As an employer, or a person in control of the premises, you are responsible for health and safety and need to take the right precautions to reduce the risks of exposure to legionella.
We pride ourselves on providing a bespoke and personal service, should you require further information or clarification on any of the above please feel free contact us for more information.
We can assist with the production off:
- Description of the water system including schematics.
- Asset registers of all associated plant, pumps, tanks etc.
- System supply source, e.g. mains.
- Are conditions present that will encourage bacteria to multiply (temperature, dead legs, sediment etc.)?
- Is there a means of creating and disseminating breathable droplets, e.g. shower, taps, hoses etc.?
- Who may be exposed?
- Are legionella bacteria present?
