Grain dust explosions have been occurring in the U.S. for the past twenty years. In the past ten years, there have been an average of ten explosions a year, resulting in nine fatalities and 93 injuries. In more than half of these cases, the ignition source remains unidentified. The effect of ambient humidity on the likelihood of a dust explosion has been discussed for many years. However, no investigation into a possible link between the two has been carried out. In this study, we analyzed local weather data and grain dust explosions during the period 2006 to 2014 to measure potential relationships between the two events. The 84 analyzed explosions do not show any trend with regard to prevailing temperatures, or relative or absolute humidity. In addition, the ignition source could not be identified in 54 of the incidents. The majority of grain dust explosion incidents occurred at grain elevator facilities, where the dust generation potential was high compared with grain processing industries.
在过去二十年里，美国一直发生谷物粉尘爆炸事件。在过去十年中，平均每年发生十起爆炸，造成九人死亡，93人受伤。在超过一半的此类事件中，火源仍不明。关于环境湿度对粉尘爆炸可能性的影响已经讨论多年。然而，尚未对两者之间可能存在的联系进行调查。在本研究中，我们分析了2006年至2014年期间的当地天气数据和谷物粉尘爆炸情况，以衡量这两个事件之间的潜在关系。所分析的84起爆炸事件在盛行温度、相对湿度或绝对湿度方面均未显示出任何趋势。此外，在54起事件中无法确定火源。大多数谷物粉尘爆炸事件发生在谷物筒仓设施，与谷物加工业相比，那里产生粉尘的可能性很高。
