When checking water temperatures in an intensive care room, water should be run at:

Water should be run at low flow when checking temperatures in an intensive care room to minimize the risk of transmission of Legionella and other pathogens. In healthcare settings, it is crucial to maintain a safe environment for vulnerable patients.

Running water at a low flow helps ensure that temperature readings more accurately reflect the actual conditions of the water while reducing aerosol generation, which could potentially spread bacteria, including Legionella. High flow scenarios can create more turbulence and agitation in the plumbing system, potentially disturbing biofilms or pathogens that may exist in the pipes.

Additionally, low flow allows for a stable temperature reading without introducing new water from the system that might not accurately represent water temperatures in critical areas like faucets or showers used by patients. This procedure helps ensure compliance with safety and health regulations, supporting effective Legionella management in sensitive environments like hospitals.
