A waste fireworks and firecrackers destruction project in Nantong city required the destruction process to be safe and efficient. On the basis of fully understanding the characteristics of the fireworks and firecrackers to be destroyed, the principles of destruction were clarified, and the destruction plan was carefully designed in combination with the specific characteristics of the project. In the open offshore area, a 20 m×20 m site with a depth of 2 m and a maintenance slope of about 5 m was first pre-set as the destruction site. The entering and exiting roads were then arranged reasonably so as to improve the unloading efficiency. According to the traffic conditions between the storage and the destruction site, the transportation route and time were determined. At the same time, in order to ensure the safety of the transportation process, the vehicle speed, loading and unloading, placing and other technical requirements were strictly regulated. According to the size of the destruction site and the location of fireworks to be destroyed, the minimum discharge angle was calculated as 12°. Combined with the maximum height of the fireworks liftoff, the discharge area, escape area and scattered area were determined in the process of destruction, based on which the safety warning range of the destruction was set as 120 m. The joint control measures of warning personnel and UAV were adopted to monitor the destruction process in real time to ensure that the fire hazard was controlled in the initial stage. The destruction was thorough, safe and accident-free with good results.
