| Abstract |
A local exhaust hood was designed to capture and contain aerosol emissions of ribavirin during drug administration. It consisted of a compound hood incorporating two concentric hoods, the exterior of which was exhausted. The compound hood and ventilation system were evaluated for leak rate and inside hood aerosol concentration as a function of exhaust flow rates. The leak rate was reduced from an average of 98% with the traditional head hood to an average of less than 1% with the compound hood with exhaust port. The system's performance may lead to an 18% to 25% decrease in inside hood concentration of aerosol entering the hood. An exhaust flow rate in the range from 1.0Lpm below to 1.0Lpm above inlet flow rate from the small particle aerosol generator reduced the leak rate to an average of less than 1%. The compound hood was found to reduce the aerosol concentration in the room by 126x as compared to the single hood currently being used. |
