In-Mine Evaluation of Smoke Detectors.

PB92193234

Publication Date	1992
Personal Author	Morrow, G. S.; Litton, C. D.
Page Count	21
Abstract	The report presents the results of an evaluation of smoke detectors placed in conveyor belt entries of underground coal mines. The selected mines are located in six different Mine Safety and Health Administration (MSHA) Coal Mine Safety and Health districts; are operated by seven different companies; and use atmospheric monitoring systems from seven different manufacturers. Principal concerns are early detection and warning of fires, reliability of operation, frequency of maintenance, and adaptability of detectors to monitoring systems and the mining environment. The data contained in the report provides for some comparisons between smoke detectors and carbon monoxide (CO) sensors, specifically in the areas of early detection of fires and nuisance alarms due to diesel exhaust contaminants. Finally, recommendations are presented that discuss performance standards, sensitivity tests, detector classification, and maintenance.
