What Is Legionella?

 

Legionella is a common bacterium found in natural environments including ponds, rivers and lakes. The bacteria can also be supplied in small counts within mains water supply. Where there is water and the conditions of creating water droplets (aerosol), people using or within the area of these services may be at risk.

 

What is Legionnaires Disease?

 

Legionnaires Disease is a form of pneumonia, which can be fatal. The most at risk are the very old and the very young, the ill and smokers to name a few. Legionella bacteria can also cause other, less harmful illness such as Pontiac fever and Lochgoilhead fever, which can affect all people.

The main route of infection is through inhalation, by inhaling airborne water droplets that contain Legionella. It cannot be spread from person to person. The majority of cases or outbreaks of the disease have been via domestic water services, evaporative cooling towers, and spa pools.

What are the factors required to create risk of legionnaires disease?

 

  • The presence of legionella
  • The presence of population vulnerable to exposure
  • A means of creating aerosol
  • Suitable conditions for Legionella to proliferate
  • Lack of control & management measures

Conditions and contributing factors to legionella growth include:

 

  • Temperatures between 20-45°C
  • Available nutrients (including: sediment, biofilm, algae, scale, rust, material, etc.)
  • Presence of biofilm on surfaces of water
  • Poor or in adequate management including training and awareness

How to achieve legionella compliance?

You must understand how to:

  • Identify and assess sources of risk
  • Manage any risks
  • Prevent or control any risks
  • Keep and maintain the correct records and carry out any other duties you may have.

When is a legionella risk assessment required?

 

“Duty holders should arrange to review the assessment regularly and specifically when there is a reason to suspect it is no longer valid. An indication of when to review the assessment and what to consider should be recorded and this may result from, e.g.:

 

  • A change to the water system or its use;
  • A change to the use of the building where the system is installed;
  • New information available about risks or control measures;
  • The results of checks indicating that control measures are no longer effective;
  • Changes to key personnel;
  • A case of Legionnaires disease/legionellosis associated with the system”

What are the legal workplace requirements?

 

Duties under the Health & Safety at Work Act 1974 (HSWA) extend to risks from Legionella arising from work activities. In addition, harmful micro-organisms (biological agents) are subject to the Control of Substances Hazardous to Health Regulations 2002 and Amendment 2003 and 2004 (COSHH) and management responsibilities – The Management of Health and Safety at Work Regulations 1999 (MHSWR).

The Approved Code of Practice 2001 (ACoP) (L8) Legionnaires’ disease: the control of Legionella bacteria in water systems provides practical guidance with respect to the HSWA regulations 2, 3, 4 and 6, COSHH regulation 6 and MHSWR regulation 3 and has been approved by the Health & Safety Commission with the consent of the Secretary of State. The code should not be regarded as law; however, in the event of prosecution, it is likely that a court will employ the Code in defining acceptable standards.

The ACoP places responsibility on employers to:

  • Identify and assess risks from Legionella.
  • Manage the risks, including the appointment of a person or persons to take managerial responsibility and to provide supervision and training of personnel.
  • Avoid the use of systems that give rise to a foreseeable risk of Legionella, or where this is not practicable, prepare a written scheme of precautions.
  • Keep appropriate records.

The origins of legionella

 

The disease was first identified in 1976 after an outbreak at the convention of the American legion in Philadelphia where over 220 people were infected resulting in 34 deaths.

Since then, numbers of cases have slowly risen with latest figures showing 200-250 reported cases of Legionnaires’ disease each year in the UK.

The risk of contracting the disease from a contaminated water source is minimised by following the Approved Code of Practice by the HSE (ACoP L8) and HSG 274.
