National Institute of Occupational Safety and Health, Japan
The aims of the Division of Occupational Exposure Science (DOES) are to scientifically clarify the behavior of chemicals in the workplace environment, and how and in what amounts they are taken into workers' bodies and to determine what can be done to prevent exposure. For these purposes, DOES is studying 1) the development and evaluation of measurement methods using chemical analysis, physical measurements, and electron microscopy; 2) behavioral analysis to clarify the relationships between the situations of workers and fluctuations in the concentrations of chemicals in the workplace; and 3) ways of optimizing of chemical concentration reduction measures and protective equipment. Also, based on this knowledge, it investigates chemical-related occupational accidents and proposes measures to prevent similar accidents.
Evaluation of the collection efficiency of filters for personal exposure sampling.
Dust generation system simulated for powder handling processes by a drop method.
Measurements of the dust concentration at a tunnel construction site.
Optimization of personal sampler mounting onto a reflective safety vest and/or back protector for tunnel construction workers.
Exposure monitoring for investigation of an occupational accident (evaluation of lead exposure during removal of lead-containing paint from a steel beam of a road bridge).
