Stay safe during extreme cold
When you know severely cold weather is coming, remember to take steps to prepare:
- Take caution when using portable heating devices like space heaters.
- Cover exposed skin and watch out for frostbite.
- Make sure the exhaust pipe on your car is clear of snow, as well as your house's heater vent.
- To prepare for power outages, stock up on batteries, flashlights, and canned goods.
Heat emergencies
During periods of extreme heat, we'll declare a heat emergency and open community centers as cooling centers.
- BCYF Community Centers become cooling centers during a heat emergency.
- Never leave children and pets alone in cars. Cars heat up quickly even if the windows are slightly open.
- Drink more water no matter how active you are.
