  4. Maintain a stockpile of emergency supplies.
  5. Prepare homes for potential power outages.
  6. Stay informed about weather updates.

These precautions help protect against the risks associated with cold weather while promoting a safe living environment.

1. Dress in Layers: Dressing in layers involves wearing multiple clothing items to trap air and provide insulation. This strategy allows residents to adjust their clothing based on indoor and outdoor temperatures. According to the National Weather Service, losing heat through the body can lead to hypothermia, making layered clothing essential during severe cold.

2. Insulate Pipes: Insulating pipes means wrapping them in materials that reduce heat loss. This can prevent pipes from freezing and bursting, which can cause significant water damage inside homes. The American Society of Plumbing Engineers estimates that homeowners can prevent such issues by insulating their pipes with foam or fiberglass sleeves, especially those in unheated areas.

3. Use Space Heaters Safely: Space heaters should be used with caution to prevent fire hazards. Keeping them at least three feet away from flammable materials and never leaving them unattended can reduce the risk of fire. The National Fire Protection Association reported that space heaters were involved in 79% of home heating fire deaths in a recent year, emphasizing the importance of safety precautions.

4. Maintain Emergency Supplies: Maintaining a stockpile of emergency supplies, such as non-perishable food, water, first-aid kits, and flashlights, prepares residents for unexpected power outages or severe weather conditions. FEMA recommends having at least a three-day supply of food and water for each family member.

5. Prepare for Power Outages: Preparing homes for potential power outages includes having backup heating options, like wood or gas stoves, and ensuring that generators are in proper working order. According to the Federal Emergency Management Agency (FEMA), preparation can greatly reduce stress during significant weather events.

6. Stay Informed About Weather Updates: Regularly checking weather updates from reliable sources helps residents stay informed about rapidly changing conditions. The National Oceanic and Atmospheric Administration (NOAA) advises using alerts and apps to receive timely notifications about winter storms or hazardous conditions in Charleston.
