Inhalation Exposure of Grain Samplers and Grain Inspectors to Carbon Tetrachloride... 

In 1981 the North Central Region of the National Agricultural Pesticide Impact Assessment Program (NAPIAP) funded a project entitled "Inhalation Exposures of Grain Samplers and Grain Inspectors to the RPAR Pesticide Carbon Tetrachloride. ... 

Develop a method to assess the workday exposure of Minnesota Department of Agriculture grain samplers and grain inspectors to CClj, ... 

Time Weighted Average (TWA) breathing zone exposures for both grain samplers and grain inspectors were below 1 ppm. 

When the information on the odor threshold and colorimetric tube methods were demonstrated to the various inspectors and their supervisors, the colorimetric tube method was preferable for detecting the presence of CCljj concentrations in grain samples to be inspected. Inspectors who had been relying on CClj. odors as a method of detection were shown that such a method was inadequate to keep exposures below the OSHA and ACGHI ceilings. As a result of the explanation as to why odor threshold detection was Inadequate, the Inspectors could understand how a more sensitive detection system could reduce their exposures to CClj,.
