B2: PEAK Part 1: Making Sense of Direct Reading Instrument Data Streams

Ernest N. Morial New Orleans Convention Center 

Room: 293 

CM Credit Hours: 1 

The many direct reading instruments (DRIs) currently available to the industrial hygienist have enhanced methods for obtaining accurate, meaningful data as it is being measured. The resulting information can be invaluable for detecting trends in exposure levels and for educating both workers and management concerning the air quality conditions of a workplace immediately after the measurements are taken. However, managing and interpreting a large stream of data values from a DRI can be daunting.

This educational session is designed to provide a variety of methods to analyze DRI data using Microsoft Excel features. It will begin with an overview of features of a DRI that affect the quality of the obtained data and methods to organize the real-time data in a spreadsheet. Various methods to evaluate trends in workplace concentrations in relation to both time-weighted average and short-term exposure limits will also be discussed. A third component of the session will be to demonstrate what can be done, and what cannot be done, when attempting to make comparisons between different worksites measured with a DRI.

Upon completion, the participant will be able to:
• Determine the features of his/her direct-reading instrument that influence the quality of the obtained data.
• Logically organize the collected real-time data in a spreadsheet.
• Evaluate trends in workplace concentrations using real-time data.
• Compare concentrations measured at different sites within a workplace using real-time data.
