Thanks to your government, safety is our number one priority. To explain some of those wacky safety pictures I offer you the following: Homeland Security Safety Picture Guide
Be sure to look at the guide (above link) in case an emergency happens.
Your government is always concerned about your safety. The following Civil Defense Film, while a little dated, still contains important information that may keep you alive in an emergency.
By understanding the illustrations of emergency behavior and viewing the video, you should be well prepared in the event of an emergency.
