EHS Safety News America has shared an excellent video and article surrounding the topic of combustible dusts and the hazards that they pose to safety in industry.
Any combustible material (and some materials normally considered noncombustible) can burn rapidly when in a finely divided form. If such a dust is suspended in air in the right concentration, it can become explosive. The force from such an explosion can cause employee deaths, injuries, and destruction of entire buildings. Such incidents have killed scores of employees and injured hundreds over the past few decades.
Materials that may form combustible dust include metals (such as aluminum and magnesium), wood, coal, plastics, biosolids, sugar, paper, soap, dried blood, and certain textiles. In many accidents, employers and employees were unaware that a hazard even existed.
Businesses which face the risk of fire or explosion due to the presence of combustible materials often foresee the need to monitor the safety of their employees using new best practices. To monitor worker safety in an area with combustible particulate present, certified Intrinsically Safe equipment is a requirement. The lone worker safety solutions by Blackline GPS are certified Class I, Division 1, A, B, C, D and Class II, Division 2 E, F, G Intrinsically Safe, making it appropriate for use in environments where combustible or explosive gases, metal dust, and grain dust poses a risk.
