Performance of Multiple HEPA Filters Against Plutonium Aerosols
Field sampling has provided C. Elder, and Manuel Gonzales general criteria defining plutonium aerosol size characteristics and activity concentrations from typical plutonium operations. Two fabrication facilities have aerosols with activity median aerodynamic diameter’s (amad) ranging from 2 to 5 pm; the two research and development facilities indicate amad’s ranging from 1 to 4 ~; and a recove...
متن کاملPerformance of breathing filters under wet conditions: a laboratory evaluation.
INTRODUCTION Heat and moisture exchangers in combination with a bacterial and viral filter (HMEF) are widely used during general anaesthesia. Excess patient secretions occluding the HMEF have been responsible for previous case reports of airway obstruction. A previous study suggested that differences in HMEF design might contribute to filter obstruction under wet conditions. METHODS We tested...
متن کاملHEPA EXHAUST FILTER IV HEPA SUPPLY FILTER I / All
A microbiological survey of the effectiveness of class II (laminar flow) 'safety' cabinets found in the UK in the last six years is recorded. Only two of the nine units tested approached the containment of aerosols achieved by a good class I (exhaust protective) cabinet. The others were potentially hazardous if used with pathogenic material. The National Sanitation Foundation and the British St...

متن کاملINDOOR AIR QUALITY: Wood-Burning Stoves Get Help from HEPA Filters
The total role that the environment plays in contributing to premature death and disability remains sketchy, but researchers working with the World Health Organization (WHO) continue to flesh out the details. Now four WHO researchers have estimated the global burden of certain toxic substances for which adequate data are available. They have calculated that in 2004 2 at least 8.3% of all preven...
