Abstract
The operation of diesel engines in underground areas requires careful attention to space ventilation in order that the concentration of toxic combustion products be held within acceptable limits. These ventilation requirements and the bases for calculating them are reviewed in the paper. A special hazard, the case of an engine rebreathing its own exhaust as a result of inadequate ventilation, is identified and described. This special case is shown to result in progressively accelerated carbon monoxide discharge with possibilities for very rapid development of extremely hazardous CO levels in the vicinity of an inadequately ventilated engine. Overall, the problem of maintaining safe atmospheres is lessened as the amounts of toxic pollutants from engines are reduced. Methods used to approach the minimal pollutant yield--and thereby minimal air poisoning hazard--are also discussed.
