Health facilities are locations where healthcare is provided. Hospitals, clinics, outpatient treatment centers, and specialist care centers such as birthing centers and psychiatric care centers are all examples of these facilities. Essentially, healthcare facilities are locations that house many residents, including staff and patients. Healthcare facilities are often considered a hygiene zone, since they must protect and preserve their clean air for the benefit of patients. However, it is also a location populated with bacteria and toxic pollutants that pose a significant risk to human health.
