High negative pressure limits dispersion of airborne contaminants in hospitals and renovation sites
(WorldNews Finland)

Maintaining a high negative pressure in airborne infection isolation rooms of hospitals (over -10 Pa) and in renovation sites (over -5 Pa) effectively limits the dispersion of airborne contaminants and dust, a new study from the University of Eastern Finland shows. Inhaled airborne particles at work can cause adverse health effects, and this is why it is important to prevent exposure to them. Moreover, the control of contaminants released from internal sources within an enclosed workspace also plays an important role in protecting other persons working in or occupying adjacent areas from adverse biological and chemical exposure. Better ventilation is needed in hospital anterooms The...
