This chapter discusses real-time exposure assessment techniques to solve workplace hazards. Two case studies illustrate useful equipment and techniques for controlling problems of dust and gas exposure in industry. These case studies also show how integrating ergonomic and industrial hygiene principles pinpoints exposure sources and provides effective solutions. Industrial hygienists often measure a worker's exposure to industrial contaminants by sampling the air he or she breathes. A small, battery-powered pump draws a known flow rate of air through a filter or other collection medium for a measured period of time. The collection medium is analyzed to quantify the contaminant collected and to compute the average exposure for the sampling period. Although these results indicate the extent of exposure, integrated air sampling provides little insight into the specific causes of the worker's exposure. Recommendations for controlling air contaminant exposures are often based upon the industrial hygienist's judgment and can result in control measures that do not address the major air contaminant exposure sources. Direct-reading instruments and data-recording devices can overcome the problem by recording events and exposures in the workplace as a function of time. The data from such a system associates events and exposures, and promotes more effective and focused recommendations for controlling the air contaminant exposures.
