DETROIT – Amid the chaos in Las Vegas, thousands of people rushed to safety, leaving loved ones to wonder if they made it out OK.
There's a quick and effective way to let friends and family members know if you are safe when a major incident takes place.
When it comes to checking in, some people send out a quick tweet or try to text a loved one. The American Red Cross also has a hotline you can call during a national disaster, in order to put yourself on a safe list.
But Facebook has become the easiest way to let people know your status.
On the left-hand side of the Facebook home page, scroll down to find the crisis response page. There, you'll see a list. You can click on the one that applies to you, and at the top, you can mark that you're in the affected area.
Then, you click if you're OK. You can also search for friends in the area to see if they've marked themselves as safe.
