Protective engineering structures are designed to withstand and mitigate the effects of penetration explosions. However, such explosions can generate a variety of toxic gases, including TVOC, CO₂, CO, HCHO, C₆H₆, NH₃, Rn, NO_x, PM_2.5, PM₁₀ and etc. The presence of these toxic gases poses a significant threat to the health and safety of personnel within these structures. Therefore, it is crucial to have timely knowledge of the changing concentrations of toxic gases during penetration explosions in order to effectively minimize harm to occupants. To address this issue, a method is proposed to monitor the concentration of toxic gases in real time during penetration explosions in protective engineering structures. The first step involves eliminating the influence of the explosion itself by using nylon ropes to fill the target projectile. This ensures that the focus is solely on monitoring the toxic gas emissions resulting from the penetration process.

Next, a comprehensive monitoring system is implemented to measure the concentrations of various toxic gases. This system utilizes advanced sensors and detectors capable of detecting TVOC, CO₂, CO, HCHO, C₆H₆, NH₃, Rn, NO_x, PM_2.5, PM₁₀ and etc. The sensors are strategically placed within the protective engineering structure to provide accurate and representative measurements. promptly relays the information to a centralized control center. This enables personnel responsible for the safety of the structure to monitor the changing gas concentrations and take appropriate measures to protect occupants. For example, if the concentration of a particular toxic gas exceeds a predetermined threshold, an alarm can be triggered, prompting immediate evacuation or the activation of ventilation systems to mitigate the risks. By implementing this real-time monitoring system, the potential harm caused by toxic gases during penetration explosions in protective engineering structures can be effectively minimized. The ability to promptly detect and respond to changes in gas concentrations ensures the safety and well-being of personnel within these structures. This research contributes to the advancement of protective engineering practices and provides valuable insights for the design and operation of structures in high-risk environments.
