We know certain chemicals cause problems in the workplace. The issues now are: Where do they occur in the workplace? How can we best evaluate them? What are the procedures for dealing with them safely? Many books simply define the problem and tell you that you need a program. Air Sampling and Industrial Hygiene gives you a guide to air sampling protocols from start to finish. The book presents sampling technology updated with today's tools - such as microcircuitry and remote sensing. The authors emphasize an interdisciplinary approach to understanding how air monitoring can adequately report current environmental conditions associated with outdoor media, indoor remediation efforts, proximal equipment, interior line monitoring, and the interrelationship of ventilation parameters. In addition to providing the how-tos of sampling, this guide covers the basics of chemical risk assessment, biological assessment, engineering evaluation of mechanical system design criteria, and chemical or process engineering hazard assessments. It presents the information using text, text outlines, graphics, and pictures - including cross sections of instrumentation and side bars to elaborate on complex concepts. Faulty readings caused by poor sampling techniques can be very costly. This book provides the how-tos for making design engineering and on-site decisions as to instrumentation selection and scheduled usage. Air Sampling and Industrial Hygiene Engineering will allow you to complete the sampling process systematically and correctly from initial suspicions to the use of obtained results.

This report provides technical information on air sampling that will be useful for facilities following the recommendations in the NRC's Regulatory Guide 8.25, Revision 1, ''Air sampling in the Workplace.'' That guide addresses air sampling to meet the requirements in NRC's regulations on radiation protection, 10 CFR Part 20. This report describes how to determine the need for air sampling based on the amount of material in process modified by the type of material, release potential, and confinement of the material. The purposes of air sampling and how the purposes affect the types of air sampling provided are discussed. The report discusses how to locate air samplers to accurately determine the concentrations of airborne radioactive materials that workers will be exposed to. The need for and the methods of performing airflow pattern studies to improve the accuracy of air sampling results are included. The report presents and gives examples of several techniques that can be used to evaluate whether the airborne concentrations of material are representative of the air inhaled by workers. Methods to adjust derived air concentrations for particle size are described. Methods to calibrate for volume of air sampled and estimate the uncertainty in the volume of air sampled are described. Statistical tests for determining minimum detectable concentrations are presented. How to perform an annual evaluation of the adequacy of the air sampling is also discussed.

There is a growing need for environmental measurement personnel who possess a solid understanding of the techniques of air pollutant sampling. This essential book explains the fundamentals of air sampling, develops the theory of gas measurement, and presents several "how-to" examples of calibration and use of air and gas sampling devices. Other topics covered range from the basics of pressure measurement and units conversion to specific discussions regarding the use of a Volatile Organic Sampling Train or a SUMMA-polished canister sampling system.

Current federal guidance on occupational radiation protection recognizes the importance of conducting air flow studies to assist in the placement of air sampling and monitoring equipment. In support of this, Pacific Northwest Laboratory has provided technical assistance to Westinghouse Hanford Company for the purpose of evaluating the adequacy of air sampling and monitoring locations at selected Hanford facilities. Qualitative air flow studies were performed using smoke aerosols to visually determine air movement. Three examples are provided of how air flow studies results, along with information on the purpose of the air sample being collected, were used as a guide in placing the air samplers and monitors. Preparatory steps in conducting an air flow study should include: (1) identifying type of work performed in the work area including any actual or potential release points; (2) determining the amounts of radioactive material available for release and its chemical and physical form; (3) obtaining accurate work area descriptions and diagrams; (4) identifying the location of existing air samplers and monitors; (5) documenting physical and ventilation configurations; (6) notifying appropriate staff of the test; and (7) obtaining necessary equipment and supplies. The primary steps in conducting an air flow study are measurements of air velocities in the work area, release of the smoke aerosol at selected locations in the work area and the observation of air flow patterns, and finally evaluation and documentation of the results. 2 refs., 3 figs.
