Where can sparks and embers occur?
Potential causes of sparks and embers in production plants include self-ignition, overheated machine parts, and foreign objects in machine parts and transport systems that can cause sparks that can quickly ignite combustible material or cause dust or gases to explode.
In modern production plants, raw materials and products are often moved quickly and automatically from storage facilities via conveyor belts and through advanced processing plants. This means that even if there is no combustible material in the area in which sparks and embers occur, they can quickly be carried via extraction or transport systems to other areas of the plant where raw materials, production equipment or finished products can ignite. This is often where the worst damage to buildings, equipment, raw materials and products occurs, so it is vital that sparks and smouldering embers are extinguished as soon as they occur.
The table below shows statistics on fire risk in some of the most at-risk industries, as well as specific areas of operations where the risk of fire and explosion is greatest:
