Did you know that carbon monoxide (CO) is generally produced during excavating work done with the help of explosives? This gas could seep into your dwelling and cause serious health issues.
The Régie du bâtiment du Québec (RBQ) has associated itself with the ministère de la Santé et des Services sociaux (MSSS) in view of inciting contractors doing explosive work to distribute to anyone concerned a carbon monoxide detector as well as the leaflet entitled Danger: explosives.
The Guide of preventive practices - Carbon monoxide poisoning and blasting work [Fr], published by the MSSS, indicates that following a blasting operation, carbon monoxide can be retained in the soil or under the concrete slab of a building, then migrate slowly. It is therefore important to monitor the air during several days (a period of 14 days is recommended) after the blasting operations, using carbon monoxide detector.
