Spark detection finds burning sparks and embers as they travel through industrial ductwork, where they pose a serious risk of starting a fire or dust explosion in a filter, silo or store. By detecting these sparks the instant they appear, the system allows them to be dealt with before they reach somewhere dangerous. It is an essential safeguard for any process that conveys dust or combustible particles by air. MEP designs, supplies and installs spark detection systems for industrial applications across the UK.
Highly sensitive infrared detectors are mounted on the ducting and continuously watch for the light emitted by a spark or glowing ember passing through, even in complete darkness inside the duct. Because material inside the duct moves fast, the detectors respond in milliseconds so that action can be taken while the spark is still in the pipe. Spark detection is normally paired with an extinguishing stage, such as a rapid water spray, which quenches the spark automatically before it can reach the filter or silo.
Spark detection is used across industries that generate and convey dust or fine particles, including woodworking, furniture manufacture, food processing, milling, textiles, paper and recycling. It is a key part of managing the fire and explosion risks that DSEAR requires employers to control. Detection can trigger extinguishing, raise an alarm, or divert and isolate the affected line, depending on the risk. We assess the process and ductwork and position detectors, with extinguishing where needed, to protect the critical points.

A system that detects burning sparks or embers travelling in industrial ductwork, so they can be dealt with before they cause a fire or dust explosion.
Infrared detectors on the ducting sense the light emitted by a spark passing through, responding in milliseconds even in the dark interior of the duct.
The system typically triggers a rapid extinguishing spray to quench the spark, and it can also raise an alarm or isolate the affected line.
