• Description:
  Four respirator particulate filters were evaluated. Penetration of monodisperse-dioctyl-phthalate (117817) (MDOP), silica (7631869), dust, lead (7439921) fumes, and sodium-chloride (7647145) (NaCl) aerosol was measured by light scattering and propane flame photometry. The effects of humidity and charge on NaCl penetration was also studied. For the test chemicals, penetration ranged from and 0.03 to 6.7 percent, respectively, on high efficiency and on dust and mist filters. For each filter type a decrease in NaCl penetration with increasing humidity was noted. Significantly higher NaCl penetrations were also observed when the aerosol charge was neutralized. The authors conclude detection might improve with a more sophisticated system using hydrogen flame, instead of propane flame photometry, and more refined electronic equipment.
