What should I do if the power went out in my whole house?

If the power goes out in your whole house, first check if your neighbors are also affected. If they are, contact your utility company to report the outage. Use flashlights or battery-powered lanterns for lighting, and unplug electronic devices to prevent damage from power surges when the power comes back on. Keep your refrigerator and freezer closed to maintain the cold temperature. If the outage is prolonged, consider moving perishable items to a cooler with ice packs.
