Legionella sterilisation at tram depot in September 2012

Council statement on the discovery and sterilisation of very low levels of legionella bacteria during tram depot commissioning in September 2012

Statement

A spokesman for the City of Edinburgh Council said:

"A very low count of legionella bacteria was detected in a washing unit at the tram depot in September and no staff or members of the public were at risk at any point. 

"The area was treated and sterilised by independent water hygiene specialists immediately in a way that went over and above legal requirements.

"The building continues to be monitored monthly and wash systems are flushed daily to maintain the highest safety standards."

 

Background

The sample was detected in a washing unit which is separate to the main depot building. At the levels discovered only further sample testing was required by law. However, depot management ordered an immediate disinfection as a precaution.

The sample was taken on 27th September and an 'all clear' certificate was received on 28th September.

Legislation allows organisations to maintain testing and monitoring regimes and to identify and sterilise legionella, whilst maintaining appropriate records of actions.

Edinburgh Trams employ a water hygiene specialist to monitor and maintain water systems across the organisation. Testing that discovered the bacteria was carried out as part of tram depot commissioning. 

The approach taken was in line with the Health & Safety Executive's Legionella Code of Practice.

Edinburgh Trams' water consultants, H2O Water Services, are registered with the Legionella Control Association.

Discovery of Legionella bacteria in industrial buildings isn't unusual and each day many samples are tested at laboratories across Scotland.

All appropriate actions and measures were taken to handle the issue.
