A fire brigade officer in Guang'an city recently received a utility patent on his fire extinguisher system for use on exterior walls of high-rise buildings, the first design of its kind in the nation. Inventor Zhu Xiongjun said traditional extinguishers inside buildings are of little use if the exterior is on fire. His design installed on the top of buildings uses tanks, tubes, sensors and an alarm system to automatically spray water.
