Breathing zone samples were analyzed for nitroglycerin (55630) (NG) and ethylene-glycol-dinitrate (628966) (EGDN) at the Radford Army Ammunition Factory (SIC-3483), Radford, Virginia in September 1981. Area samples were analyzed for acetone (67641), diethyl-ether (60297), ethanol (64175), and n-butyl-acetate (123864). NG concentrations in the personal samples ranged from 0.001 to 0.028 parts per million (ppm). Five of 77 samples were above the NIOSH recommended standard of 0.01ppm. These were all in the rolled powder propellant rolling operations. All NG samples were below the OSHA standard of 0.2ppm, 15 minute peak. All EGDN samples were below the analytical detection limit. Concentrations of the solvents were below all relevant federal standards. The authors note that according to the management, there were several reports of headaches among the employees of the facility. These suggest that some uptake of NG is occurring. It is not clear whether this occurs primarily from inhalation or skin absorption. Recommendations include conducting 8 hour monitoring of personal NG concentrations and using personal protective equipment in the rolled powder propellant rolling operation where NG concentrations exceed the NIOSH standard.
