A fire column is a type of exothermic reaction that occurs when a flammable liquid is heated to its boiling point and then ignited. The resulting column of flame can be quite tall, often reaching several feet in height. Fire columns are often used as decorative elements in public places such as parks and plazas. However, they can also pose a serious safety risk if not properly monitored. In highly populated areas, fire columns can easily become overcrowded and pose a danger to onlookers. In addition, if the column is not properly contained, the surrounding area can quickly catch fire. As a result, it is important to exercise caution when using fire columns in any public setting.
