What is one of the primary uses of water in healthcare facilities?

Water is essential in healthcare facilities for the maintenance and operation of various therapy equipment. For instance, many therapeutic devices, such as hydrotherapy tanks and ultrasound machines, rely on water for effective functioning. Water is also crucial in washing and sterilizing equipment, ensuring the hygiene and safety of patient care.

In the context of the other options, while water may play a role in decorative settings, this is not a primary or critical use in healthcare. Its role in storing chemicals is generally limited and more focused on specialized applications. Preventing fire hazards is more accurately addressed through firefighting systems and protocols, rather than relying on water as a primary measure. Thus, the maintenance of therapy equipment represents a vital and focused application of water in healthcare facilities.
