Legionella Basics
The Regulations

The HSE Approved Code of Practice " The Control of Legionella Bacteria in Water Systems" known as L8 was released and came into force on the 8th January 2001. This new document amalgamates the two previous documents and has allowed existing information to be consolidated and new information to be added. A need to revise the previous documents arose because industry standards and working practices seeking to control legionella have continued to evolve; our understanding of the disease process and the microbiology of the primary causative organism, Legionella pneumophila, has also further advanced.

Consequently, many of the revisions are intended to amplify detail rather than change change concepts. Crucial amongst these concepts is that it is not the absence (or presence) of legionella in a single sample that is significant but the existence of the circumstances that could lead to rapid proliferation of the organism to hazardous levels.

A preventative strategy must therefore be in place.

Who's Responsible ?

Under general health and safety law the building owner or building manager has a duty of care to ensure that employees and visitors are in a safe environment and adequate precautions have been taken

What are my duties under the law ?

You have to consider the risks from legionella that may affect your staff or members of the public and take suitable action. As an employer or a person in control of the premises (eg a landlord), you must keep records and check that what has been done is effective.

The following items are essential in compliance with the Health and Safety law

1/Identify and assess sources of risk
