Abstract
A walkthrough survey was conducted at IMC (SIC-2869), Sterlington, Louisiana, on May 19, 1977, to determine potential hazardous exposures during the production of nitroparaffin, with emphasis on 2- nitropropane (79469). Facility operations were observed, and a bulk sample of nitroparaffin was analyzed by gas chromatography/mass spectroscopy. Personal air samples were collected regularly by the company and by OSHA. About 50 workers were involved in the production and handling of nitroparaffin. Based on company and OSHA data, the daily exposure to 2-nitropropane was about 1 part per million (ppm), well below the current OSHA standard of 25ppm. In the bulk sample of nitroparaffin, 1-nitropropane (108032) and 2- nitropropane were identified. Nitromethane and nitroethane were not observed. Another component could not be positively identified, but it was a straight chain aliphatic amine. The authors conclude that additional testing should be conducted for aliphatic amines and nitrosamines because amines can combine with other nitrogen containing compounds to form carcinogenic nitrosamines. Inclusion of the facility in a retrospective cohort mortality study, pregnancy outcome study, or cross sectional medical study of 2-nitropropane was not recommended because the exposed population was small and the time since onset of exposure was short.
