What category of medical gas systems would have no impact on patient care if it failed?

In the context of medical gas systems, the classification into categories is based on the impact that their failure would have on patient care. Category 4 systems are designed for functions that do not directly impact patient care. These systems may include gas supply for non-critical applications, such as background operations or maintenance functions in healthcare facilities.

Because these systems are not essential for patient treatment or safety, their failure would not jeopardize patient health or hinder immediate medical care. On the other hand, categories 1 through 3 are associated with varying degrees of impact on patient care, from critical life-supporting systems, which are crucial for patient survival and treatment, to those that, while important, may affect a patient's comfort or convenience.

Understanding the role of each category is essential for healthcare constructors to ensure the right systems are maintained and prioritized, particularly in emergency and operational risk management.
