Pictogram legionella bacteria prevention

An infection with the legionella bacterium can cause infection of the lungs and airways. When spraying with legionella contaminated water the risk of people getting infected is high. Circumstances in which the Legionella bacterium multiplies to numbers that may threaten health include: water temperature between 25 and 50 °C, still water, which we often find in the reel's fire hose. This is why there must be a legionella prevention warning sign at the reel which states that the fire hose reel can only be used in case of fire.
