During the world-famous Holi festival, people throw and smear each other with a colored powder (Holi color, Holi powder, Gulal powder). Until now, adverse health and environmental effects (skin and eye irritation, air pollution, and respiratory problems) have been described in the available literature. However, the literature lacks data on the flammable and explosive properties of these powders during mass events, despite the fact that burns, fires, and explosions during the Holi festival have taken place many times. The aim of the article is to present the fire and explosion parameters of three currently used Holi dust and cornflour dust types as reference dust. The minimum ignition temperature of the dust layer and dust cloud, the maximum explosion pressure and its maximum rate of growth over time, the lower explosion limit, the limit of oxygen concentration, and the minimum ignition energy were determined. Tests confirmed that the currently available Holi powders should be classified as flammable dusts and low-explosive dusts. The likelihood of a fire or explosion during mass incidents involving a Holi dust-air mixture is high.
在世界闻名的胡里节期间，人们互相投掷和涂抹彩色粉末（胡里颜色、胡里粉末、古拉尔粉末）。到目前为止，已有文献描述了这些粉末在使用过程中对健康和环境的不良影响（皮肤和眼睛刺激、空气污染和呼吸道问题）。然而，尽管胡里节期间已经发生了多次烧伤、火灾和爆炸事件，但这些粉末在大规模活动中的易燃和爆炸性特性的文献数据却很缺乏。本文的目的是介绍目前使用的三种胡里粉尘和玉米淀粉粉尘类型的火灾和爆炸参数，作为参考粉尘。测定了粉尘层和粉尘云的最低点火温度、最大爆炸压力及其随时间的最大增长率、爆炸下限、氧气浓度极限和最小点火能。测试证实，目前可用的胡里粉末应被归类为易燃粉尘和低爆炸粉尘。在涉及胡里粉尘-空气混合物的大规模事件中，发生火灾或爆炸的可能性很高。
