Effectiveness of real-time monitoring.
Advances in air sampling. ACGIH Air Sampling Procedures Committee, eds. Chelsea, MI: Lewis Publishers, 1988 Jun; :243-250
Real time monitoring of occupational exposure to chemical agents was discussed. The advantages of direct real time instruments were summarized. These include the ability to obtain rapid analytical results and eliminate sample handling and storage. Real time monitors can monitor fluctuations in exposure concentration as well as obtain time weighted average exposure concentrations. This capability facilitates investigating work environments that have highly transient exposures and is useful for educating employees and employers about work practices and exposures. Disadvantages of real time analyzers include their high initial cost and increased complexity compared with conventional sampling techniques. Applications of real time analyzers were discussed using as examples monitoring nitrous-oxide (10024972) exposures in hospital operating rooms by transportable direct reading infrared spectrophotometers, monitoring ethylene-oxide (75218) exposures in hospitals and commercial sterilization facilities and monitoring phosphine (7803512) exposures during grain fumigation operations with portable gas chromatographs fitted with photoionization detectors. The authors note that the portable gas chromatographs appear to be less rugged than the infrared instruments; however, if properly packaged they travel well.
