Dust Monitoring Solutions

Continuous Dust Monitoring

Combustible Dust Explosions are a huge concern to anyone in the processing business. A CSB (Chemical Safety Board) study found that 281 dust-related incidents from 1980 to 2005 killed 119 workers and injured 718. The National Fire Protection Association (NFPA), who sets the standards to protect facilities from fire and explosion risks, and the Occupational Safety & Health Administration (OSHA) who is enforcing these standards with increasing vigilance are both generating stricter regulations, and the need for fugitive dust monitoring systems is becoming increasingly more prevalent. Millions of dollars are lost every year due to these fires and explosions. The risk can be significantly reduced by regular clean up procedures and inspections, but it will always be present in any industrial environment.

VarSci’s solution is with our partner Sintrol's Continuous Fugitive Dust Monitors (CFDM). These devices are designed to be permanently mounted in EX or non-EX rated industrial areas; therefore, they can be located in manned and unmanned locations. They will continuously monitor potential combustible and hazardous dust accumulation, and alert operations when levels become unacceptable. Through its radio link, RS485, or 4-20mA analog connections, the devices can be interfaced to your facility’s existing SCADA system, chart recorder, or other datalogging software to continuously trend interpolated dust concentration levels.


Dust fires and explosions are triggered by five events happening simultaneously, this is called the Dust Pentagon. When a dust fire ignites, it is called deflagration. When primary deflagration occurs a shockwave is then sent around the process equipment, causing accumulated dust in the room to go into suspension. Once the fire escapes from the process it creates a source of ignition for the now looming dust cloud in the area, this is secondary deflagration. The results of both primary and secondary deflagration are often deadly.
