In order to guarantee the safety of city buses in recent high temperatures, the Chongqing Public Transit Group has installed automatic fire-extinguishers on approximately 4,000 buses throughout the city's main urban districts, according to news released by the group a few days ago.

"When the temperature inside or outside the engine bay has exceeded 170 degrees Celsius, the device will automatically release inert gases and use dry powder to put out the fire," stated a technician from the Chongqing West Public Transit Co., Ltd. (CQNEWS) (Translated by Liu Kan)
