Basics

An explosion causing a typically stable, yet combustable fuel to have more surface area (due to forming a dust cloud) and thus ignight and Deflagrate, and often Detonate
Can lead to MAJOR industrial accidents SUCH AS
Main industries at risk are sugar mills, flour mills, metal powder production, saw mills, and essentially anything dealing with powder, or processes that can produce it
The ignition source can be somthing as small as static electricity, or machine heat
This is also the operating principle behind educational labs, entertainment devices , and thermobaric explosives

Avoidance Strategies

Source collection via shop vac attachments etc
Collection devices such as Cyclonic Seperators and Electrostatic Precipitators as well as other Air Purifiers and Air Scrubbers
Humidifiers to reduce dust levels

Close at risk areas off/modularise them
Reducing oxygen (either by reducing the levels in the work area/room to lower levels, or via working under an inert atmosphere (may not need argon etc, notrogen should work assuming the process allows for it)
