Which of the following systems is NOT a focus for implementing Legionella control measures?

• A. Cooling towers
• B. Fire protection systems
• C. Hot water systems
• D. Faucets and showers

Answer: (B)

Implementing Legionella control measures is crucial in systems where the bacteria can thrive and pose a risk to public health. Fire protection systems, while critically important for safety, typically do not operate in a way that supports the growth of Legionella. These systems are generally designed to use water only in emergencies and often do not maintain the warm water conditions that facilitate the proliferation of this bacteria. In contrast, cooling towers, hot water systems, and faucets or showers are all operational systems that can create environments conducive to the growth of Legionella due to factors such as temperature, stagnation, and aerosolization. Therefore, control measures are focused on these types of systems to prevent outbreaks and ensure safety, whereas fire protection systems are excluded from this focus since they do not provide a sustained environment for the bacteria to develop.
