Guidelines to Develop Design Criteria for Working-Atmosphere Monitoring Systems.
NIOSH 1972 Dec:15 pages
Guidelines for the development of design criteria for working atmosphere monitoring systems were presented. The threshold limit values of the gas, as well as the specificity, reproducibility and accuracy of the monitoring system, are important design criteria. Interferences must also be identified and eliminated. Disadvantages and benefits of several monitoring systems, such as gas detecting tubes, ion selective electrodes, chromatography, long path and remote sensors, were outlined. The authors conclude that design criteria can be written for specific gases when applied within a known set of circumstances. The criteria must include the portion of the working atmosphere to be monitored and should be based on a sampling and analytical procedure.
