The maximum allowable concentration of particulate contaminants in instrument air is established to protect what?

The maximum allowable concentration of particulate contaminants in instrument air is established primarily to protect patient safety. Instrument air is used in various medical applications, including respiratory therapy and the functioning of medical devices. High levels of particulate contaminants can lead to malfunction or degradation of sensitive equipment, potentially compromising the effectiveness of treatments or procedures performed on patients. By regulating the concentration of particulates in instrument air, medical facilities can ensure that the air used in devices that directly interact with patients is clean and safe, thereby minimizing risks to patient health and safety.

While equipment performance is indeed important, the most direct and critical concern in medical settings revolves around the safety and well-being of patients, making this the primary focus for establishing concentration limits.
