Large buildings with wide-span roofs may collapse if a tornado hits.
If you are in one of these buildings and cannot leave, take cover under a sturdy structure such as a table or desk. If you are in the home or office, go to the basement or take shelter in a small interior ground floor room such as abathroom, closet, or hallway. Alternatively, protect yourself by taking shelter under a heavy table, desk, or work bench. Stay away from windows, outside walls and doors. If possible, cover your body with a blanket or sleeping bag; protect your head with anything available, even your hands.
Barn damage or destruction from tornadoes can have a variety of impacts that cross over many sections in this resource. Ensure you have your barn safety plan, flock relocation or humane euthanasia plan in place as well as your general emergency plan for injury to humans.
