Taylor S, Initiative TC. A new method for quantitative, in-use testing of laboratory fume hoods. Containment testing of laboratory hoods in the as-used condition. Design, Construction, Maintenance, Health and Safety.
Massachusetts Institute of Technology. The occupational exposure of a hypothetic hood operator was determined 27 times through direct reading. Exploring the use of less environmentally damaging gases for use in tracer gas testing.
Ashrae Std Testing Laboratory Fume Hoods
Shahid Beheshti University of Medical Science; Air flow was visualized through injecting low and high volume of smokes at 18 tests. The environmentally hostile characteristics of SF6 as well as its cost are the major concerns. Linear regression of the results ashgae used to consider the substitution of ethylene with SF6.

The occupational exposure of the 101-95 hood operator to SF6 and ethylene were 4. The performance of a laboratory hood was evaluated using ASHRAE standard method at three different ventilation capacity as well as three different volumetric flow rates of injected SF 6 while a mannequin was located at the front of hood. Appl Occup Environ Hyg ; 15 2: Alternative gases to meet.
Laboratory fume hood performance. Chemical Fume Hood Guide: The average and standard deviation of face velocity at hood inlet were 0. Meanwhile, the exposure of a mannequin stationed at the front of hood was measured. Dale T, Maupins K. Method of testng performance of laboratory fume hoods. Application of non-dispersive infrared NDIR spectroscopy to the measurement of atmospheric trace gases.
Ashrwe velocity was measured times using a thermal anemometer TA-2 model.
