Hello,

As a starting point you need to check if any of your water systems, with the right environmental conditions, could be a source for legionella bacteria growth. There is a reasonably foreseeable legionella risk if water system:

• has a water temperature between 20–45 °C
• creates and/or spreads breathable droplets, e.g. aerosol created by a cooling tower, or water outlets
• stores and/or re-circulates water
• likely to contain a source of nutrients for the organism to grow, e.g. rust, sludge, scale, organic matter and biofilms

If all your water is from the mains then focus on the places that water may sit for longer periods such as unflushed toilets etc. then evaluate the risk and decide on arrangements.

Tell me more about your workplace and water systems you have I may be able to help you more.

Hi Bunster,

I am also currently looking at the Legionella risks in our premises and would greatly appreciate a look at the audit document you have mentioned. I don't think there are any high risk areas here apart from two showers which employees use from time to time; however I'm no expert.

Would you possibly be able to send me over theocument?

GB1977 - I am glad you have raised this question as I was going to post the exact same qquestion once I got home today!
