Hot spots occur as a result of spontaneous combustion or outside influences, such as overheated bearings or an electrical short. Deep inside a silo, bunker or pile, hot spots will continue to increase in temperature until the area eventually collapses. This creates a hazardous combustible dust cloud that can lead to an explosion. Generally, there are warning signs well before hot spots reach this stage. These can include smoke, a burning smell, discoloration on silo walls or an increase in carbon monoxide. In a confined space, such as a silo or bunker, higher temperature hot spots can quickly lead to explosions. Gaining an understanding of how progressed the hot spot is before planning a course of action is crucial. Your supplied FLIR Thermal Imaging Cameras can be utilized from multiple directions to approximate where a hot spot is located.
