Legionnaires Disease (Legionella Bacteria)

What is Legionnaires Disease?

  • It is a potentially fatal form of pneumonia.
  • On average there are 400 cases of legionnaires disease reported each year in the UK.
  • Outbreaks are most commonly associated with hot and cold water systems and cooling towers.
  • It is contracted by inhaling either tiny droplets of water aerosols or in droplet nuclei contaminated with Legionella deep into the lungs.

The Law

  • Legionnaires Disease is governed by the following laws;
  • Health & Safety at Work Regulations
  • COSHH (Control of Substances Hazardous to Health)
  • RIDDOR (Reporting of Injuries, Diseases & Dangerous Occurrences Regulations
  • The Duty Holder or Responsible Person could be charged with manslaughter if the precautions mentioned in the above Regulations are not followed or face huge fines.

Who is classed as a Duty Holder/Responsible Person

  • Employers have a duty to their employees or others.
  • A self-employed person has a duty to themselves and others.
  • Landlords have a duty to their tenants and others.

How to control the Legionella Bacteria?

  • Avoid water temperatures between 20 and 45 degrees.
  • Ensuring the system operates correctly and safely and is well maintained.
  • Avoid water stagnation that may encourage the growth of bio film.
  • Avoid use of materials in the system that can harbour or provide nutrients for bacteria and other organisms to grow.
  • Keep the system clean to avoid build up of sediment, which may harbour bacteria.
  • The use of a suitable water treatment programme where it is safe to do so.
  • It is therefore highly recommended that you carry out a Legionella Test if you are a Landlord.
