Graduate Theses, Dissertations, and Problem Reports

Respirators are a common form of protection when working in environments where workers are exposed to harmful agents. One exposure that has not been rigorously tested is cigarette smoke. Air sampling was conducted to test the effectiveness of four different respirators N95 Respirators for various concentrations of cigarette smoke and seal conditions and for different respirators. The Moldex 2200, Moldex 2300 (exhalation valve), Gerson 1730, and 3M 8210V (Exhalation valve) were used for testing. The set concentrations were 100,000: 200,000: and 400,000 cm3 with an error allowance of 20% for each concentration. Different flow rates (15, 30, 50, and 85 …
