||Respiratory exposure of grain inspection workers to carbon tetrachloride fumigant

||The point at which peak exposure occurs during the grain inspection process has been identified as the off odor test in which the inspector smells the grain sample for rancidity, sourness, etc. Ambient concentrations of CCl4 in 7750 grain samples submitted for inspection were determined by colorimetric tube, and these concentrations were an estimate of peak grain inspector exposure to CCl4. The average ambient concentration of CCl4 per grain sample was 1.69ppm ▒8.35. Approximately 380 time-weighted average (TWA) CCl4 exposures for grain inspection workers were determined by using passive dosimeters. All TWA exposures were less than 2ppm. Variables are examined, such as location of work, grain type, time of year and grain transportation vehicle - all of which are known to the sampler or inspector before performing their job functions and which affect potential exposure.
