To Reduce Legionella Risk at the End of the Season
Actions to be Taken
- Perform chlorine shock by adding chlorine to cold water tanks. The target free chlorine level is 3 ppm, with a 24-hour retention time within the system.
- Increase the water temperature inside boilers to 60-70 ºC, then run hot water from all showers and taps (including rooms, hammam, hairdresser, etc.) at a pencil-thin flow for 5 minutes each. Perform thermal shock.
Record Keeping
Write down all performed procedures on appropriate forms or prepare minutes and sign them.
Important
Do not forget to warn guests about the risk of scalding before thermal shock.
Note
The required actions may be more than those mentioned above. The important points are included in the reminder, but the priority may vary depending on the risk situation.
