Florida Hospital Halts the Spread of Airborne Infections Using Aeroseal
Nemours Childrens’ Clinic in Jacksonville, Florida, sealed its air duct system using Aeroseal duct sealing to improve HVAC airflow and ensure germs are removed through the building’s exhaust and not recirculated through air leaks in ductwork as shown in Figure 1.
There were so many retrofits and extensions added to the ventilation system at Nemours Children’s Clinic that engineers couldn’t pinpoint the airflow problems. What they did know was negative pressure and inadequate ventilation throughout the more than 30-year-old building could contribute to the spread of nosocomial infections. Their first steps in taking control of the situation was to seal the duct leakage in the exhaust shafts located on each floor and in the main shaft running down the length of the 11-story building.
