Many goods carried on conveyor systems are highly combustible with the power to ignite. Black and brown coal, biomass, industrial confetti, sulphur and recycling products are all examples of goods that can pose a fire risk during transportation. If they do ignite and the conveyor has no fire protection measures in place, then the fire can quickly spread to holding hoppers, blending, crushing or other processing areas of the plant to become a potentially major incident with catastrophic fire damage and substantial consequential losses. Transit sensors for heat detection are a good option in detecting fires in areas with sudden peaks of temperature can lead to explosions and deflagration.
