You assume the entire risk of relying on this Information. Specifications of Calcium Hydroxide. 2010. Transport hazard class(es) Hazard classification : 8 14.4. To determine if a substance is a candidate to be added to the Environmental Emergency Regulations, Environment Canada has developed a risk evaluation methodology based on the following hazard categories: For more information on the methodology for setting threshold quantities in the Environmental Emergency Regulations, please refer to Summary of Risk Evaluation Framework for Determining Quantity Thresholds and Concentrations for Substances under the Environmental Emergency Regulations. They neutralize acids exothermically to … Genium. The new proposed threshold is set to 3 tonnes for the following reasons: A “moderate” classification in NEMISIS has some of the following characteristics: there is a risk to endangered or threatened species or their habitat, or a significant life threatening risk to other wildlife; the incident causes significant disruption of public services or property damage and community health is or will be threatened; impacts of the incident on the environment are significant (e.g. At least some ingredient disclosure. Because calcium hydroxide, solution does not have a vapour pressure greater than 10 mmHg (1.33 kPa) at 25°C (CHEMINFO, 2010), the substance does not have sufficient volatility to constitute an inhalation danger.

To minimize environmental impacts, many researchers and government agencies emphasize the importance of using smaller quantities of deicers to increase the efficiency of mechanical ice removal instead of melting ice completely in place and producing high volumes of deicer-saturated run off.
