CDC Statement on Helmets and Tornadoes
The Centers for Disease Control and Prevention continues to recommend, as its first recommendation, that people in the path of a tornado find a shelter or a tornado-safe room. The safest place in the home is the interior part of a basement. If possible, get under something sturdy such as a heavy table or workbench. If outdoors, lie down in a gully or ditch. Head injuries are common causes of death during tornadoes, and individuals may decide to use helmets to protect their heads. However, because the time to react may be very short, people who choose to use helmets should know where they are and have them ready. Helmets should not be considered an alternative to seeking appropriate shelther considered just one part of their overall home tornado preparedness kit.
