Common causes of conveyor fires include friction due to misalignment or a loss of belt traction, as well as belts that have combustible residue on their surface. However, conveyor roller failure is a leading cause. The motion of conveyors can also cause fire to spread quickly, which is an additional incentive for effective monitoring.

The environmental conditions also need to be taken into account, typically underground conveyor belts have increased humidity and dust. When designing a system using a flame or ember detector it is important to note that these units are optical devices. Taking that into account it is important to have air purging using a clean and dry air supply.
