Does the production process of electro-optic powder fall under Category B or Category C?

What is the fire classification for the grinding and screening workshop where electroceramic powder made from urea-formaldehyde resin is produced? Is it Category C or Category B? For Category B, the main concern is dust explosion, I’m not sure if that’s correct; please advise those with more experience.
I’m not sure about the fire hazard category of electric jade powder, but can dusts that are classified as Class C combustibles be considered free from the risk of dust explosions?
Determining whether it is a Class B or Class C factory involves not only considering the fire hazard category of the substances themselves, but also factors such as the production process and environmental conditions. It is recommended to consult the \"Code for Fire Protection Design of Buildings and Explanations to the Code\" before making a decision. A prerequisite for a dust explosion is that the dust is flammable, but it is not specified that it must be of Category B. So Category A and Category C are also possible
Reply to 3# ckwcba: Substances classified as Category C can experience dust explosions, but does that mean their production process is upgraded to Category B?
We originally all did it according to Category C
