Home Security & Survival (Ukrainian Experience): ​The Two-Wall Rule: During shelling, stay in a room with at least two walls between you and the street (usually a hallway). This protects from shrapnel if windows shatter. ​Water Storage: Fill your bathtub and all containers immediately. In high-rises, water pumps stop without electricity. ​Child Safety: Prepare a "comfort bag" for kids with favorite toys and noise-canceling headphones to reduce stress from explosions.
