NIOSH conducted this HHE to investigate complaints from underground coal miners of illnesses, including respirato ry problems, asthma, and skin irritation, after exposure to rock glues in the course of their work duties. NIOSH was requested to provide guidance in establishing a com­ pany medical surveillance program for those workers with exposure to rock glue adhesives containing isocyanates. ...

The National Institute for Occupational Safety and Health (NIOSH) in early 1974 began industrial hygiene studies of vinyl chloride exposed workers. Three VC monomer plants, three VC polymerization plants, and seven PVC fabrication plants were surveyed. V polymerization plant workers and workers in one job category in VC monomer plants were exposed to average levels above 1 ppm. The highest aver...

Although total carbon (TC) can be consistently quantified by various aerosol carbon measurement methods, the demarcation of TC into organic carbon (OC) and elemental carbon (EC) has long been inconsistent. The NIOSH and IMPROVE protocols are most widely used for thermal/optical analysis (TOA), but current knowledge rests in the description that the NIOSH protocol usually gives lower EC values t...

This paper provided a brief summary of the current strategic goals, activities, and impacts of the NIOSH (National Institute for Occupational Safety and Health) occupational injury research program. Three primary drivers (injury database, stakeholder input, and staff capacity) were used to define NIOSH research focuses to maximize relevance and impact of the NIOSH injury-prevention-research pro...

field study was conducted to evaluate seat designs on shuttle cars. Eight operators R A participated in evaluating seat designs on the basis of perceived levels of vehicle jarring/jolting and discomfort. Researchers also measured the levels of vehicle jarring/jolting. Four basic seat designs were compared on low and mid-coal seam shuttle cars during production operations at two underground coal...

background: manual handling, lifting, or carrying of material is responsible for non-fatal injuries among employees in industries. it is the second most prevalent reported risk factor in workplaces that can lead to potential manual handling accidents and longer-term musculoskeletal disorders (msds). the aim of this study was the evaluation of manual material handling using the american national...

The National Institute for Occupational Safety and Health (NIOSH) created the NIOSH Science Blog to provide a new way to further the Institute’s long-standing commitment to optimizing two-way communication with partners, stakeholders, and the public. The blog provides an opportunity for NIOSH scientists and stakeholders to present ideas to each other while engaging in robust scientific discussi...
