Episode 82: Cooling Towers

In this episode Tejaswi Shetty, Microbiologist and Senior Property Risk Consultant at Greencap joins host Mark Reggers to discuss cooling towers and the hazards they can present. A cooling tower is a heat rejection device used to lower the temperature of the water contained within it through evaporative cooling. It expels waste heat to the environment outside the building allowing the cold air to move into the internal parts of the building and cool the structure. Sometimes the dispelled air may be contaminated with Legionella bacteria, that if inhaled by susceptible people, may develop into legionnaires’ disease.
