As part of a NIOSH program for the development of monitoring methods, we have produced guideline information to help others with the evaluation of sampling and analysis technology. The first publication in this series was "Guidelines for Air Sampling and Analytical Method Development and Evaluation," published in 1995. It was developed primarily for methods relying on sampling media requiring sampling pumps. A similar approach to method evaluation has been taken for direct-reading gas and vapor monitors. A document entitled "Guidelines for the Evaluation of DirectReading Monitors" has been produced along with an Addendum that specifically addresses the needs of the first responder community for direct-reading monitors. The new guidelines provide a summary description of the available types of direct-reading monitors and discuss the experimental work necessary for their evaluation in assessing occupational exposures. The experimentation includes evaluation of physical and operational characteristics, response time, calibration, linearity, drift, environmental effects, interferences, limit of measurement, and bias and precision. The guidelines document includes recommendations on data interpretation for accuracy, measurement uncertainty, bias and precision, and suggestions for the treatment of data from alarm-only monitors. The addendum further addresses special needs of the first responder community such as monitor ease-of-use in harsh environments. The addendum describes an ease-of-use test program for hands-on monitor evaluation by qualified first responder participants. These guidance documents will be made available on the NIOSH website in 2006.
