severe snow and ice conditions

en español

How we address severe winter conditions can create specific environmental problems, indoors and out. This page provides information about how to be aware of and reduce risks when severe snow and ice is forecast.

Homeowners often use gasoline-powered generators for emergency electricity but these release deadly carbon monoxide (CO).

Municipalities and airports can plan ahead to use deicing chemicals help ensure safe transportation but avoid harming local ecosystems or contaminating drinking water supplies.

Prepare for snow and ice

Around your home:

People get sick or die each year from carbon monoxide or "CO" poisoning due to unsafe use of generators.

  • ALERT: Generator exhaust is toxic. Always put generators outside well away from doors, windows, and vents. Never use a generator inside homes, garages, crawlspaces, sheds, or similar areas. Carbon monoxide (CO) is deadly, can build up quickly, and linger for hours. More information.
  • Never try to heat your home using a "combustion appliances" like a gas stove, oven, barbeque grill, or dryer. Never operate any gas-burning heater or other appliance in a poorly vented or closed room, or where you are sleeping.

For municipalities and airports:


  • Manual for Deicing Chemicals: Application Practices– The results of a study about minimizing the loss to the environment of chemicals used in controlling snow and ice on highways.
  • Road Salt Application and Storage - Application and storage of deicing materials, most commonly salts such as sodium chloride, can lead to water quality problems for surrounding areas. Municipalities in areas with snowfall that requires deicing must ensure proper storage for materials such as road salts.
