Follows these recommendations for businesses in tornado-prone areas.
While there is no way to eliminate all the damage of a direct hit from a violent tornado, businesses in tornado-prone areas can that steps that, for most tornadoes, will minimize damages to facilities and the losses associated with business disruptions. These measures will also help protect businesses from other types of high wind and thunderstorm-related weather risks outside of tornado-prone regions.
Build or retrofit for wind resistance
For new construction
- Work with an architect or contractor to incorporate wind mitigation techniques and high wind-rated products when constructing your building, including safe areas for personnel. This will minimize structural risks by improving the building’s ability to withstand pressures created by specified high winds, and strengthening roof and wall connections, roof systems, walls and wall covering, windows, doors, and skylights. Note: It is less costly and more effective to harden buildings during design and construction rather than later.
For an existing structure, not built to wind mitigation standards
- Consider retrofitting, especially when remodeling or replacing building components.
- Retrofitting may include:
- Bracing and strapping the roof.
- Adding recommended fasteners, ties, reinforcements, roof covering and anchors as building components are modified and maintained.
- Making entry doors and overhead doors more wind resistant.
- Building a safe room to protect against tornadoes.
Close ALL windows and doors
Close all windows, exterior doors, garage doors, and interior doors to keep out flying debris and help keep the roof on. It is a myth that you should open windows during a tornado.
