本計畫針對有機過氧化物的危害特性進行全面分析，結合現場訪視與風險評估，分析化學品在儲存與操作中的高風險因素，並提出實用的改進建議。測試結果顯示，部份有機過氧化物的分解放熱量超過高能材料標準，且在分解過程中釋放低閃火點的易燃氣體（如丙酮、叔丁醇），顯著提升火災和爆炸風險。包裝容量對熱分解行為和自加速分解溫度（SADT）影響顯著，容量越大則散熱較差，SADT下降2至10 °C不等，此外稀釋劑會改變分解行為並降低穩定性，需在風險評估中加以考量。 現場訪視中發現，多數工廠在溫控、通風、洩壓、防火和應變設施方面仍有改進空間，部份場所的通風與釋壓控制不足，容易引發氣體積聚與爆炸風險。結合實驗數據與現場訪視觀察，進行極端情境下的風險模擬與評估顯示，溫控不良和應變設施不足的工廠風險偏高。 基於上述發現，本計畫構建一套風險辨識與管理流程，針對可能的熱失控情境提出具體建議，包括強化溫控、完善通風與洩壓、提升應變能力、優化數據更新與風險評估。基於風險的改善措施將能有效降低企業儲存和操作有機過氧化物的風險，同時提升自主防災韌性，為長期安全管理提供科學基礎。

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.
