Legionella: Hot Tub Management
Hot tubs and spa pools have been linked to cases of Legionnaires' Disease in spas, leisure centres, hotels and private residences. The very nature of hot tubs gives them an increased susceptibility to legionella build-up, meaning that regular legionella risk assessments conducted by professionals is highly recommended.
Where appropriate measures are not taken to prevent legionella, hot tubs and spa pools are particularly prone to encouraging legionella build up. This is due to several factors:
- Temperature – hot tubs and spa pools are usually kept at temperatures between 30°C and 40°C – the perfect temperature for legionella to thrive.
- Air-jets – spa pools and hot tubs often include air jets or similar devices to agitate the water. These jets can also produce aerosols (water droplets, or water spray), meaning that if legionella is present in the water, it is more likely to be inhaled.
- Multiple bathers – commonly, water in hot tubs and spa pools is not replaced after each bather, and with a much higher ratio of bathers to water volume than a swimming pool, this means that a significant build up of organic matter can occur, which supports bacteria such as legionella.
