国家运输安全委员会(NTSB)确定,2023年3月宾夕法尼亚州一家巧克力工厂发生致命爆炸,造成7名工人死亡,爆炸是由腐蚀的蒸气管和故障的天然气装配引起的。 The National Transportation Safety Board (NTSB) determined that a deadly explosion at a Pennsylvania chocolate factory in March 2023, which killed seven workers, was caused by a corroded steam pipe and a faulty natural gas fitting. 工厂缺乏适当的应急程序和疏散政策,造成雇员之间的混乱。 The factory lacked proper emergency procedures and evacuation policies, leading to confusion among employees. NTSB还建议安装天然气泄漏侦测警报器。 The NTSB also recommended the installation of natural gas leak detection alarms.
