This school security system displays safe evacuation routes during shootings and disasters

FastCompany: In the event of an emergency, evacuating a building can be one of the most important safety measures. But depending on the kind of emergency—whether a fire or a tornado or an active shooting—taking the right evacuation route or finding shelter can be the difference between life and death. Go To Green is a new emergency evacuation system that’s designed to automatically direct people to go, or stay, in the safest place during an emergency. Designed primarily as a response to active shooter situations in schools, the system uses a simple system of colored lights to direct people to the safest evacuation route, and away from danger.

“Most children in the United States play red light, green light. So it just makes sense to use lights that we’re all preconditioned to pretty much from birth,” says Ernie Williams, founder of Go To Green.

Located in school hallways and inside and outside classroom doors, the lights turn green to show people where to move and red to show them where to avoid. Red and blue lights flash at the point nearest the emergency source, be it a fire or a shooter.

It essentially turns buildings themselves into real-time evacuation tools, showing in a very visual way where to go during an emergency, and where not to. Williams, a former Marine, spent 25 years in the military and says the idea for a more intuitive active-shooter security system and evacuation guide came from direct experience. “I spent a little bit of time getting shot at and understood the problem with indoor systems,” he says. “They can’t pick up an active shooter in real time.” Williams says Go To Green’s sensors act independently to be able to pinpoint where a threat exists, even if it’s moving.

“Let’s say a guy’s walking down the hallway and he shoots, the sensors change and the pathways may change,” he says. The system is currently installed in 20 schools, mostly in Texas, where the company is based. None have been called into action for active shooter situations, but they have been activated during tornadoes, alerting students and staff to get indoors and avoid dangerous places within buildings. The company is backed by O’Leary Ventures , the investment arm of Shark Tank star Kevin O’Leary.

We don’t have to get on the radios, we don’t have to get on the phone with them. They look up and see a visual and this automatically takes them to the threat,” Williams says. Go To Green is one of many school security systems and tools that have come to market in recent years.

Amanda Klinger, director of operations at the nonprofit security training organization The Educator’s School Safety Network , says products on the market vary widely in their efficacy. “We’ve really seen the industry explode in growth,” Klinger says. “There’s a lot of money to be made.” After reviewing material on the Go To Green active-shooter security system, Klinger says it has the potential to be a valuable part of a school’s security system, but that security systems alone can only go so far. Training and threat prevention are also necessary to reduce the chances of very rare and extreme emergency events like active shooter situations.
