Hospitals contain many different types of spaces with various requirements, which require the establishment and verification of pressure gradients for infection control to meet Department of Health requirements. Surgery suites, which include operating rooms and clean and dirty corridors, are generally positively pressurized to surrounding areas. Some patient rooms are designed to be either positively or negatively pressurized to surrounding areas depending on the risk to the patient and others. For example: COVID-19 isolation would be negative pressurization to contain airflow to infected area. Airtest also sets comfort systems for heating and cooling requirements to maintain a comfortable and healthy work environment for both patients and frontline healthcare workers. In addition to other TAB services, on a hospital project Airtest is responsible for establishing and documenting these gradients. Airtest provides initial setup and does scheduled retesting of critical environments to meet DOH requirements.
