Which system is not required to be surveyed as part of a Legionella water management plan?

• A. Cooling systems
• B. Medical gas systems
• C. Fire suppression systems
• D. Domestic hot water systems

Answer: (B)

In the context of a Legionella water management plan, it is essential to focus on systems that are known to harbor potential pathogens and contribute to the risk of Legionella exposure. The correct option relates to medical gas systems, which are typically not associated with water sources that could facilitate the growth of Legionella bacteria. Cooling systems, fire suppression systems, and domestic hot water systems are all essential components that can allow for the conditions conducive to Legionella proliferation, particularly through the aerosolization of water. These systems often involve water storage, and in some cases, water temperatures that can support the survival and replication of Legionella. As a result, they are required to be surveyed and monitored under Legionella management protocols to mitigate any risk associated with waterborne pathogens. Medical gas systems, on the other hand, do not involve water that is at risk of forming aerosols or containing Legionella bacteria. Therefore, they do not require the same level of monitoring and management as the other listed systems, making them the correct option in this scenario.
