The Health Hazard Information Module is the U.S. Army's computer software application for managing occupational exposure data. The project mission is to utilize automated information systems technology to improve the overall effectiveness of industrial hygiene programs. Field industrial hygiene professionals document their survey methods, findings, conclusions, and recommendations with a portable, pen-based computer. Back at the office, the data are electronically transferred to a desktop workstation. Users can generate standard or customized reports in hard copy or electronic formats. Annually, users transfer their data to a corporate mainframe computer. The software incorporates appropriate information and represents an excellent template worth examining during the ongoing international effort to standardize occupational exposure data. Planned refinements include distributing the software to other Department of Defense agencies and making it commercially available for a nominal fee through the National Technical Information Service in the near future.
