When is it required to perform system blow down in medical gas systems?

Performing a system blow down in medical gas systems is crucial after initial installation. This process involves flushing out the system to remove any contaminants, debris, or foreign materials that may have accumulated during the installation process. Ensuring the system is clear and clean from the outset is essential for the safety and efficacy of the medical gases being delivered to patients.

This initial blow down is particularly important as any impurities within the system can compromise the quality of the medical gases, potentially posing risks to patient health. It is a standard practice that sets the foundation for a reliable and safe medical gas delivery system.

Other scenarios, such as performing a blow down after repairs or during routine maintenance, though important in their own rights, are not the primary reason for an initial blow down, which is specifically to establish a contaminant-free environment immediately following installation.
