NIOSH Updates Software for Estimating Service Lives of Respirator Cartridges
NIOSH has updated its “MultiVapor” computer software for estimating breakthrough times and service lives of air-purifying respirator cartridges, larger filters, and carbon beds of any size prepared for laboratory studies. The update adds 66 new compounds, including toluene diisocyanate (TDI), methylene bisphenyl isocyanate (MDI), and styrene, to the software’s library. According to NIOSH, the updated version also features typical organic vapor (OV) cartridge parameters that are more representative of commonly used cartridges. MultiVapor is intended to help industrial hygienists or other qualified persons set cartridge change-out schedules. NIOSH states that the software should not be used as a substitute for regulatory requirements or professional judgments. The MultiVapor application can be downloaded from NIOSH’s website. Video and PDF tutorials are available near the bottom of the page.
