OP-T2-22: Snow and Ice Removal

The University employs a range of snow removal strategies to reduce the impact on the environment while addressing the challenges of Québec City’s northern climate. Snow is removed mechanically. De-icing and abrasive mixtures are prepared and applied as needed (amounts and proportions) based on the local weather forecast. A different mixture of sand and calcium chloride (less corrosive than sodium chloride) is used on parking lots, streets, and sidewalks and near buildings. Because our winters are so bitterly cold (often with temperatures below 20° Celsius), certain de-icers cannot be used because they are ineffective at these temperatures. When we get freezing rain, 1/8″ gravel is spread with a shovel onto sidewalks and near buildings to minimize the amount used while at the same time ensuring pedestrian safety.
