Legionella can be found in any man-made re-circulating hot and cold water systems such as storage tanks, calorifiers and air conditioning systems.

Infection may be caused by the creation of respirable air bourne droplets which can be inhaled.
Risks from bacteria may be found in:

  • Water systems incorporating a cooling tower.

  • Water systems incorporating an evaporative condenser.

  • All hot water systems.

  • Hot and Cold water services, irrespective of size in premises where occupants are susceptibly aged or sick.

  • Humidifiers and air washers which create a spray of water droplets and in which the water temperature is likely to exceed 20° C.
