The Legionella bacterium is most commonly found on man-made water systems. This includes:
Hot and cold water systems:
Hot and cold gravity fed water storage systems, pressurised mains-fed water systems, hot water only storage, cold water only storage.
Cooling tower ad evaporative condensers:
Cooling tower, evaporative condenser or other cooling element, the re-circulating pipe work, the heat exchanger, pumps and ancillary items such as supply tanks and pre-treatment equipment.
Hot tubs, whirlpool baths, hot spas and portable spas.
There are several factors that indicate that a water system is at risk from Legionella. Including:
These factors give rise to a category known as Potential Risk Systems, which includes humidifiers, air washers, emergency showers, and indoor ornamental fountains.
If you have any of the above in your workplace, then yes, your workplace may be at risk. The next step is to arrange a risk assessment. Even if you do not think that your water systems are a potential risk, it is the duty of the owner or duty holder to ensure systems conform to relevant health and safety regulations.
