This project systematically analyzed the hazard characteristics, conducted on-site inspections, and performed risk assessments of organic peroxides, revealing the high-risk factors associated with their storage and handling. Practical and scientific recommendations for improvement were proposed.
The analysis showed that some organic peroxides exhibit decomposition energies exceeding the standards for high-energy materials, releasing low flashpoint flammable gases（e.g., acetone, tert-butanol）, significantly increasing the risk of fire and explosion. Packaging size strongly influences thermal decomposition behavior and Self-Accelerating decomposition temperature（SADT）; larger volumes lead to poorer heat dissipation and lower SADT, with differences ranging from 2–10 °C. Dilutants also alter decomposition behavior and reduce stability, which must be considered in risk assessments.
On-site inspections revealed that many facilities require temperature control, ventilation, pressure relief, fire prevention, and emergency response systems improvements. Inadequate ventilation and pressure control in certain areas were found to increase the risk of gas accumulation and explosion. Combining experimental and field data, extreme scenario simulations and risk level assessments highlighted elevated risks in facilities with poor temperature control and insufficient emergency response capabilities.
This project established a risk identification and management framework, proposing scientific strategies to address thermal runaway scenarios. Recommendations include strengthening temperature control, optimizing ventilation and pressure relief systems, enhancing emergency response capabilities, and improving data updating and risk evaluation processes. These long-term safety management solutions help companies reduce risks and elevate their safety management standards.
