Cabinet Decision: 20th January 2011
Title of Item/Report
Legionella Control and Water Hygiene Policy and Asbestos Management Policy
Record of the Decision
Cabinet considered a report which detailed the procedures which had been in place for sometime to reduce the risk associated with Legionella and Asbestos in Council buildings.

Policy documents had been produced that took into consideration the latest guidelines on reducing the risk associated with Legionella and Asbestos. The policy documents also clearly defined levels of responsibility.

Members noted that Legionnaire's disease was a potentially fatal form of pneumonia. The bacteria reproduce to high numbers in warm, stagnant water (between 20C and 46C). Typically plumbing systems and hot water tanks, pools, showers, fire and sprinkler systems installed in Council buildings that used water and operated at temperatures in excess of 20C could generate an aerosol presenting a Legionella risk. High temperatures of 60C and over would kill the bacteria.

The main aim of the Legionnaire's policy was to reduce the risk associated with Legionella by correct; system design and operation, methods of control monitoring, and water treatment. The recommended cleaning and disinfection procedures must be considered if the risk was to be minimised.

Members noted that Asbestos was a mineral that is resistant to heat, fire and corrosive chemicals. There were three main types:

Crocidolite (blue)
Amosite (brown)
Chrysolite (white)

Members also noted that Asbestos was composed of small fibres, which can only be detected by using a microscope under laboratory conditions.

The main aim of the Asbestos policy was to ensure that any asbestos located within Council buildings was managed in accordance with relevant legislation. There would also be a requirement on contactors to demonstrate that all staff had sufficient knowledge to recognise asbestos if they encounter it.
