Shelter in Place
A classroom shelter at Healdton Elementary in Oklahoma.
On Tuesday, a gunman fired at two students at Great Mills High School in Maryland, injuring both of them.
The event was the latest school shooting in the US, where a nationwide debate on the role of guns - especially automatic weapons - in civic society is ramping up. On February 14, Marjory Stoneman Douglas High School in Parkland, Florida made headlines when gunman Nikolas Cruz allegedly killed 17 people.
There likely won't be one solution to gun violence in schools. But one Utah-based couple believes they have created a temporary way that could make students safer.
In 2013, Salt Lake City resident Jim Haslem founded Shelter in Place, a company that builds custom, military-grade refuges that can withstand bullets and weather disasters. The first shelter was installed at an Oklahoma elementary school in 2015, and hundreds of American schools have them today.
Haslem told Business Insider that orders and inquiries from school districts have skyrocketed since the Parkland shooting.
