| Summary: | +/- 25% at the 95% confidence level, are thought by some to 12). However, there are several new brands of passive accuracy standard of +/-25% at the 95% confidence level (1- active movement of air through a sampler (1). These analyses show that passive badges tend to yield higher Association (AIHA) accredited laboratory and analyzed for at a Gulf Coast oil refinery and were worn for approximate badges and tubes were sent to an American Industrial Hygiene benzene, toluene, xylene, normal hexane (n-hexane), and total charcoal tubes. This project compared the accuracy of three concentrations of contaminants. The results yielded would data was conducted to determine if there were significant differences between the passive badges and the charcoal tube different brands of passive dosimeters: the 3M 3500 OVM, the diffusive sampler is a device which is capable of taking dosimeters on the market today that may prove to be more dosimeters, although well within the National Institute of eight hour shifts. This experiment was replicated twenty- for the five analytes of concern. Scatter plots were four times for a total of twenty-five groups of samples. The further investigate the accuracy of passive dosimeters. here. More extensive research is recommended in this area to in a controlled laboratory environment using known indicate the true accuracy of each monitor, not just a lightweight, inexpensive, and easy to use. A passive or Monitor (OVM). It has been found to be well within the NIOSH monitoring airborne contaminants because they are monitors mirrored the results of the charcoal tube. These Occupational Safety and Health (NIOSH) accuracy standard of organic vapors (TOV). A statistical analysis of the reported outcomes than the charcoal tube for the analytes studied Passive monitors have become increasingly popular for precise than the 3M 3500 OVM when comparing the results to primarily with the accuracy of the 3M 3500 Organic Vapor rate controlled by a physical process, such as diffusion relative comparison of the precision. samplers. Previous research on passive dosimeters dealt samples of gas or vapor pollutants from the atmosphere at a Sampling with the various monitors should next be conducted SKC Series 575-001, and the Gilian Traceair OVM-2 to charcoal through a static air layer, but which does not involve the tubes. The four devices were placed side-by-side on workers utilized to estimate how closely the results of the passive yield inferior results to standard pump and sorbent tube |
