Cards Term Alice Hamilton Definition First female faculty meMber at Harvard Term Dusts Definition Dry partcle aerosols produced by mechanical processes (1um to 1mm). Ex. Fertilizers, dry packaging Term Fumes Definition Very fine solid aerosol particles produced from vaporized solids (<0.1um) Ex. Arc welding, metal fumes Term Mists Definition spherical droplet aerosols produced by mechanical processes (few um to <100um) Ex. spray painting Term smokes Definition complex mixture of solids and liquid aerosol particles, gases and vapors resulting from incomplete combustion Term Fibers Definition Elongated particles with an aspect ratio greater than 3:1 Term Tularemia Definition Disease associated as occupational hazard for meat packers. Term Byssinosis Definition Occupational hazard for cotton workers Ex. denim manufacturing plant Term Dust categories Definition Inhalable (<100um) Thoracic (<10um) Respirable (<4um) Term Autoclave Definition used to decontaminate biohazardous waste Term anthrax Definition also called wool sorters disease - occupational risk for imported fur workers or people working with animal hides Term leptosporosis Definition vector is cow Term PVC filters (polyvinyl chloride) Definition used to sample for silica, dusts, zinc oxide Term Autoclave Definition used to decontaminate biohazardous waste Term Formaldehyde Definition Used to fully decontaminate a biohazard safety lab level 3 Term teflon filters (polytetrafluoroethylne) Definition used to sample for anthrax and sars Term cyclone Definition used for respiable dust air sampling Term IOM Definition developed at institute of occupatonal medicine (IOM) in Scotland - 2 lpm inhalable particles inhaled by mouth and nose Term photometers Definition real time measurements of particulate matter concentration. Light diffracted from particle. Term Semi volatile sampling Definition semi-volatiles exist in vapor form and particulate form, move back and forth between the 2 states. Denuder or impinger or both in a series may be used to sample for semi-volatiles. Term denuder Definition materials diffuse to walls or screen of denuder. vapors from particles/gas mixtures. walls are coated with materials to adsorb gases (NaCO2 adsorbs HCl, HNO2, SO2) Term Elutriator Definition particles settle out in laminar flow. Verticle: particles with terminal settling velocity greater than air velocity are trapped, used in textile mills for cotton sampling. Horizontal: particles settle out as air passes between 2 plates.
