Dust explosion prevention issues

Is it necessary to use explosion-proof motors in areas with a lot of dust?
Definitely not. Go to Baidu and look up the AQ3009-2007 Safety Standards for Electrical Explosion Protection in Hazardous Areas; it specifies under what circumstances it is necessary to follow these standards
Thanks, bro. At first, one has to figure things out as they go
In areas with a lot of dust, it is best to use explosion-proof motors
It’s all forced by the inspections~~ Hehe, one just needs to pay more attention to ** and industry standards in daily life~~
The key is to consider the nature of the dust; if it is dust from ordinary rocks, soil, or similar materials, an explosion-proof motor is not necessary； If it is a flammable material such as metal, grain, or coal dust, an explosion-proof motor is required; the specific model should be determined based on the properties of the material.
What is the maximum dust concentration in the workplace that requires the use of explosion-proof motors?
I would like to ask the teachers: aside from equipping electrical devices (including power equipment and lighting) in rooms with high dust levels with explosion-proof features, does the entire room need to be designed with explosion-proof measures as well? For example, explosion venting surfaces, vestibules, concentration alarms, and so on
If the requirements are not high, positive pressure ventilation is also an option
Look at what kind of dust it is, and then determine whether the location is in a zone prone to explosions or fires, or perhaps it’s not in any such zone at all.
I have a technical question: Are there any explosion-proof requirements for ABS powder?
