Water Temperature Testing For Legionella

Water testing is the only way to determine whether legionella is present in a water system.
Water temperature testing for legionella. Below 20 c and the hot water is hot above 50 c. When state regulations or codes do not allow hot water temperatures above the range of 105 f 120 f 40 6 c 49 c for hospitals or 95 f 110 f 35 c 43 3 c for nursing care facilities or when buildings cannot be retrofitted for. Water services should be operated at temperatures that prevent legionella growth. Legionella bacteria thrives at temperatures between 20 c and 50 c so one of the key control measures for minimising the risk is to ensure that your cold water is cold i e.
That s why regular temperature. Hot water should be stored at 60 c at least in order to kill legionella bacteria. This is why the hse s guidance recommends keeping hot water above 50 c 55 c in healthcare and cold water below 20 c. Because of this and because of the risks of legionella exposure it s vital that water systems are regularly tested for the bacteria.
The water management program team should regularly monitor water quality parameters such as disinfectant and temperature levels. By monitoring these parameters the team can ensure that building water systems are operating in a way to minimize hazardous conditions that could encourage legionella and other waterborne pathogens to grow. Water temperature thermometer for legionella monitoring control legionella control internationals range of professional water temperature thermometers and legionella testing kits have been carefully selected to help those with responsibility for the routine monitoring and control of legionella bacteria in water systems.
