Quick Answer
Minimum temperature to avoid frostbite: 15 to 20 degrees Fahrenheit (-9 to -7 degrees Celsius). At these temperatures, exposed skin can freeze in a matter of minutes.
Prolonged Exposure Risks
When exposed to temperatures below 20 degrees Fahrenheit (-7 degrees Celsius), frostbite can occur within 30 minutes to an hour. This is especially true for extremities like fingers, toes, and ears. To mitigate this risk, individuals should take regular breaks in warm shelters or vehicles with functioning heating systems when traveling in extreme cold.
Preparing for Extreme Cold
Before a winter storm, it’s crucial to stock up on essential supplies, including warm clothing, non-perishable food, and a reliable means of heating. If you don’t have access to a working heater, consider alternative heating sources like fireplaces, wood stoves, or portable generators. Always follow safety guidelines when using these alternatives.
Staying Safe on the Road
When driving in extreme cold, it’s essential to check your vehicle regularly for proper tire pressure, functioning wipers, and adequate antifreeze levels. In the event of a breakdown, never leave your vehicle unless it’s safe to do so. Stay inside, run your engine occasionally to maintain warmth, and keep your phone charged in case of an emergency.
