Inadvertent generation of hydrogen from ambient temperature metal-water chemical and electrochemical reactions have been responsible for a surprising number of hydrogen explosions. This paper describes three sets of incidents involving different metals in applications that are normally considered free of explosion hazards. The first set of incidents involves wet alkaline incinerator ash with an aluminum content of at least 2%. The second set of incidents involves copper conductor electrochemical reactions in subsea electrical cable. The third set involves electrochemical corrosion reactions in galvanized dry sprinkler pipe. In all three applications, test data are discussed to elucidate the specific reactions and potential preventive and mitigation measures.

由于意外的金属-水反应导致的不寻常的氢爆炸

环境温度金属-水的化学和电化学反应无意中产生了氢气，导致了数量惊人的氢气爆炸。本文描述了三组涉及不同金属的事件，这些事件通常被认为没有爆炸危险。第一组事件涉及铝含量至少为 2% 的湿碱性焚烧灰。第二组事件涉及海底电缆中的铜导体电化学反应。第三组涉及镀锌干式喷水管中的电化学腐蚀反应。在所有三个应用程序中，都讨论了测试数据以阐明具体反应和潜在的预防和缓解措施。
