Abstract Carbon monoxide (CO) generated by explosives can migrate underground and accumulate in confined spaces. Over a five-year period in Quebec, there were a number of incidents where residents were strongly indisposed, and seven persons were sufficiently intoxicated to require hyperbaric treatment. This hazard is probably more widespread than is generally recognized, considering the lack of understanding of the problem, the insidious nature of CO poisoning and the large number of explosions (between 1000 and 1500) carried out each year in the course of civil engineering work in Quebec. This report includes the results of several studies: a retrospective study of CO poisonings based on data from various sources, a study on CO measurements carried out at construction sites using explosives and a study of various methods for limiting the propagation of CO in fractured rock in the vicinity of work with explosives. The main recommendations are aimed at civil engineering contractors and concern the implementation of procedures for limiting CO propagation. Certain appendices are available only in electronic version.
