Open face cassette (OFC) 37-mm cassette sampler for collecting airborne particles corresponding to OELV values. Has been called total dust sampler. Comparable with the 37-mm closed face cassette (CFC) in the NIOSH Manual of Analytical Methods: Particulates not otherwise regulated method no 0500, 1994.
Inhalable fraction “Mass of total airborne particles that is inhaled through the nose and mouth.” (International Organization
for Standardization, 2012)
Occupational exposure limit value (OELV) “Limit of the timeweighted average of the concentration of a chemical agent in the air within the breathing zone of a worker in relation to a specified reference period.” (International Organization for Standardization, 2012)
Personal sampling “Process of sampling carried out using a personal sampler” (International Organization for Standardization, 2012)
Personal sampler “sampler, attached to a person, that collects airborne particles in the breathing zone to determine exposure to chemical agents.”
