light source, or by the change in curmsttcreated by charged particles passing through an ionizing radkiton field. Heat can be easily sensed by<br />
a number <strong>of</strong> conventional devices, such as compensated thermocouples and thermistors. Both the absolute temperatureand rate <strong>of</strong> temperature<br />
rise areused to define alarm conditiom. The ultraviolet and intiared portions <strong>of</strong> the electromagnetic spectniin aretypically detected with vacuum<br />
tube and solid statephotodhies, photoconductive and photovoltaic cells, thermopiles and pymdectric cells.<br />

lhk report presents the results <strong>of</strong> a U. S. Bureau <strong>of</strong> Mines evaluation <strong>of</strong> smoke detectors placed in conveyor belt entries <strong>of</strong><br />
underground coal mines. ‘flte selected mines arc located in six different Mine Safe~ and Health Ah msstmtion(MSHA) ‘<br />
districts, are operated<br />
by seven dfierent companies, and use abnospheric monitoring systems flom seven dticrent manufacture. Principal concerns areearly detection<br />
and warning <strong>of</strong> f~es, reliability <strong>of</strong> operatiou fiequcncy <strong>of</strong> maintenance, artd adaptability <strong>of</strong> detectors to monitoring systems and the mining<br />
environment. The datacontained in this report provide <strong>for</strong> some comparisons between smoke detectors and CO scnsom, specifically in the areas<br />
<strong>of</strong> early detection <strong>of</strong> fms and susceptibility to nuisauce alarms due to diesel exhaust contaminants. Finally, recommendations <strong>for</strong> per<strong>for</strong>snauce<br />
standards, sensitivity tests, detector classificatiotL and maintenance are presented.<br />

A major advance in fue safety technology during the past two decsdes is the availab~ <strong>of</strong> low cost smoke detcetms based on either<br />
ionization or photoelectric detectors. However, these deteetom have some *whacks beca~e <strong>of</strong> the ~@ ~quencY <strong>of</strong> f~e ~~s ad<br />
maintenance problems. Other types <strong>of</strong> detector technologies have been developed <strong>for</strong> specflc gases, such as C02, CO. or 02, based on metal<br />
oxide semiconductors, ele@ochemiczd sensors, or optical sensors.<br />
