Excellent article that I highly recommend for all to read! The importance of addressing combustible dust related fires is highlighted here. Do you have spark detection and flame suppression as part of your dry dust collector system?

Excellent article published in Pulp & Paper Oct 2000 by Mark Williamson. The importance of addressing combustible dust related fires is highlighted here. Do you have spark detection and flame suppression as part of your dry dust collector system?

Additional safety hazards include the lack of spark detectors or suppression systems to minimize fire and explosion hazards in ventilation systems that collect combustible wood and metal dust; allowing combustible dust to accumulate

Is your facility using best engineering practices as outlined in the NFPA combustuble dust standards such as spark detection and flame suppression?

The fire resulted in the ignition of dust in the pipes leading to the dust control bag house. Automatic suppression equipment activated, but the fire ignited dust in the dust collector resulting in an audible explosion

Source for sparck detection and flame suppression

Spark detection systems are primarily used as a fire prevention method in dust collectors and pneumatic conveying systems by detecting and extinguishing sparks and embers.
