It’s a rather clever concept, don’t you think? The Czech company Amphlla offers three round fire extinguisher designs. When a fire starts, grab it off the wall and slip it around your arm. Pull the safety pin out and pull the trigger. The fire suppressant emits from an opening on the front and the case partially shields you from the fire.
This novel design offers certain advantages. It can be used one handed, leaving the other free to manipulate objects or move people to safety. Additionally, the rounded cylinder is flatter than equivalent extinguishers, so it takes up less space when mounted on a wall. This revolutionary design approach could save lives in an emergency.
