The optimal timing for applying calcium chloride in snow and ice management revolves around whether it is deployed before or after the physical removal of snow through shoveling or plowing. Pre-treatment involves applying calcium chloride before a snowfall, aiming to prevent the initial bonding of snow and ice to the pavement. Post-treatment occurs after snow removal, focusing on melting any remaining ice or preventing refreezing.
Strategic application of calcium chloride offers numerous advantages. Pre-treatment can significantly reduce the accumulation of snow and ice, making subsequent removal efforts easier and more efficient. Post-treatment addresses residual ice and helps to maintain safe walking and driving surfaces for an extended period, reducing the risk of accidents. Historically, various de-icing agents have been used, but calcium chloride’s effectiveness at lower temperatures and its ability to penetrate ice quickly have made it a preferred choice in many regions.
