National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Development and Testing of a Prototype Device to Provide Air Meeting the Occupational Safety and Health Act of 1970.

PB82166521

Publication Date	1973
Personal Author	Rodgers, S. J.; Roehlich, F.; Polite, E.
Page Count	34
Abstract	The objective of this program was to develop and test a purification device designed to provide clean air, as defined in the Occupational Safety and Health Act of 1970, to personnel exposed to automotive exhaust contaminants. Specifically, an air cleaning unit has been assembled which will remove or greatly reduce the levels or concentrations of carbon monoxide (CO), hydrocarbons (NC), nitrogen dioxide (NO2), dust or particulate matter, and heat/humidity. Design criteria for the unit were based on the results of previous research studies and analyses of numerous air samples. Unit components are standard or off the shelf items. However, extensive modifications were required in the air cooling system. The completed unit was tested first in a closed 4300 cubic foot chamber and then extensively in the Lincoln Tunnel, a congested traffic artery beneath the Hudson River. This final report summarizes the design and construction of both the air cleaning unit and the analytical module subsequently used to monitor the inlet and outlet air quality. Test results of the completed unit are reported.
