South Korea: Firefighter suggests how laser pointers can help in fighting fires
A South Korean firefighter won first prize from eBay Korea for proposing a laser pointer that projects a “net-shaped” grid onto surfaces, to determine in smoky settings if the surface is flat or has a bump. Seo Bethel of Busan developed the idea after fighting a fire where his “flashlight couldn’t show that what I thought was a wall was actually an empty elevator shaft.”
The net-like grid will make the surface contour visible.
eBay Korea hosts a contest for firefighters to find and then develop useful firefighting tools. Bethel also has submitted ideas for laser-projecting messages from the back of fire trucks onto streets. He said, “The laser pointers will display signs, such as ‘no entry’ or ‘this lane is occupied by a fire engine’. By doing so, it can help firefighters save time spent setting up a perimeter using traffic cones.”
