Throw out or repair frayed or damaged electrical cords. Never overload electrical outlets. Plan an emergency exit to use in case of fire. Install only one good lock that can be opened from the inside quickly, rather than many inexpensive locks. People trap themselves behind multiple door locks which are hard to open during an emergency.
Emergency preparedness makes good sense.
List emergency numbers and keep them by the telephone. It is not uncommon during heavy snows or ice storms to have a power outage. Canned foods and bottled water. Medicines and medical supplies. When winter weather has set in, be prepared for the cold.
