Can heavy furniture protect against tornado winds?

Question

Accepted Answer

Theoretical Protection Against Flying Debris Heavy furniture can act as a barrier against smaller flying objects and debris, potentially reducing the risk of minor injuries. For example, a heavy wooden dresser or bookshelf may be able to deflect or slow down smaller objects like books, toys, or loose items. However, this is highly dependent on the size and weight of the furniture, as well as the size and velocity of the debris.
Limitations of Heavy Furniture in Tornado Protection Heavy furniture lacks the structural integrity to withstand the extreme forces generated by a tornado. Wind speeds within a tornado can reach up to 300 mph (480 km/h), and the pressure difference between the inside and outside of a structure can be as high as 100 pounds per square inch (PSI). These forces are far beyond the capacity of heavy furniture to provide meaningful protection. Furthermore, heavy furniture may even become projectiles themselves, causing more harm than good in a tornado.
Practical Considerations for Tornado Sheltering When seeking shelter from a tornado, it is essential to prioritize a sturdy, reinforced structure or a purpose-built tornado shelter. If no such option is available, seek shelter in a basement or a small, interior room on the lowest floor of a building. Heavy furniture should not be relied upon as a substitute for proper sheltering. Even if heavy furniture is used as a last resort, it is crucial to find a safe location, such as an interior closet or bathroom, and to get under a sturdy table or desk and cover your head and neck with your arms.
