Computerization of data from continuous and sequential air monitoring systems.

Continuous and sequential area air monitoring systems are more frequently becoming a necessity in both new and existing chemical manufacturing and processing plants. While these systems have most frequently been installed to alert employees to conditions of possible acute overexposure, they generate a wealth of data valuable in documenting employee exposures over extended period of time. Within the Dow Chemical Company, use of a dedicated microcomputer with area air monitoring systems has proven helful in summarizing each days' data and in calculating month-to-date totals for use in employee exposure documentation over long time periods.
