NIOSH 1987 Jul:17 pages
In response to a request from employees at the Devil's Lake Sioux Manufacturing Corporation (SIC-2352) located in Fort Totten, North Dakota, a study was made to determine a possible health hazard from n-hexane (110543) exposure and other organic solvents used in the manufacture of Kevlar combat helmets at this facility. Ten women working as edgers had been treated for carpal tunnel syndrome. Air samples revealed concentrations of xylene (1330207) ranging from not detectable to 6.44mg/m3, toluene (108883) ranging from 0.46 to 33.2mg/m3, hexane ranging from 0.27 to 83.3mg/m3, and methyl-ethyl- ketone (78933) ranging from 20.0 to 310mg/m3. These levels were highest in the areas of the facility where edgers and glue spray booth operators worked. The author concludes that solvent exposures in these locations posed a potential health hazard. The carpal tunnel syndrome complaints appear to be related to ergonomic factors. The author recommends the substitution of less toxic materials in the workplace; applying proper engineering controls; improving local exhaust ventilation; providing protective clothing for workers; sampling of employees for organic solvent exposure at regular intervals; and informing the employees of all hazards inherent in their work.
