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.

Reliability of Presence Sensing Devices. Volume I.

PB83148643

Publication Date	1981
Page Count	107
Abstract	The functions and limitations of presence sensing devices are reviewed. A model for the performance of hazard analyses of industrial equipment and the application of the model to identify hazards in the use of presence sensing devices as guards to mechanical power presses are described. Hazards existing without device failure are analyzed, and each factor in the equation used for safety distance calculation is evaluated and its variability determined. Generic failure modes of presence sensing devices are identified, research on device calculations is reviewed, and international safety regulations are compared. Presence sensing device performance criteria are addressed.
