A halogen lamp was kept on the floor (workers tend to work near halogen lamp during acute winter due to the warmth in its vicinity) near the deshuttered materials that had just been removed from the slab of the pre-heater building of a cement plant. The deshuttering material mostly consisted of plywood soaked with diesel and grease (used as deshuttering agents), and timber. At around 4.00 a.m., a major fire broke out damaging about 20 running metres of the pre-heater building.
