Why do you need a Legionella Assessment?

Legionellosis is a very old disease, and one that few people are aware of. Although its name my be unfamiliar, legionnaires’ disease is more common than many people may realise. The disease is not transmitted from person to person, or acquired through drinking infected water. It can only be acquired by inhaling droplets that allow the bacteria to reach the lungs directly. This means that many people could unknowingly contract the disease. In is most serious form; Legionnaires’ disease can be fatal.

Legionella bacteria can multiply at a rapid rate. This is particularly the case in complex water systems. This is why larger public building are especially at risk of this bacteria presenting itself. Legionnaires disease presents itself in the form of flu like systems. This means it is difficult to diagnose and is often missed. Water vapor can appear and be inhaled from sources such as showers, hot tubs, taps and air conditioning units. With legionella bacteria present in all of these water sources, it can be easy for multiple people to become infected at once. It also means that frequent exposure can occur. With frequent exposure to legionella bacteria, the more severe the symptoms can become.

What does the assessement cover?

A legionella assessment identifies the pipework and individual assets that make up the water system. This includes taps, showers and water tanks. These assets are then evaluated to identify the risks associated with each element. The legionella assessment is reviewed at least every two years. Unless there has been a change to the system or in management/responsible person.

There are further pieces of technical guidance and support documentation, although not all may apply to your business. These include:

  • Approved Code of Practice L8 (Fourth Edition)
  • Health Technical Memoranda 04-01 (Part A, B C & Supplement D 08)
  • Health & Safety Guidance 274 (Part 1, 2 & 3)
