What is the significance of 6 pieces of powder to industry and trade enterprises?

In order to curb the hidden dangers of major safety accidents in industrial and commercial enterprises, the State Emergency Management Department has sorted out Concise Guide for Industrial and Commercial Enterprises, Eight Points for Law Enforcement Inspection of Safety Production in Iron and Steel Enterprises, Seven Points for Law Enforcement Inspection of All Production in Aluminum Processing Enterprises and Six Points for Law Enforcement Inspection of All Production in Dust-related and Explosion-related Enterprises, which are referred to as "Eight Points for Steel", "Seven Points for Aluminum" and "Six Points for Powder" for short.

Article 1: Different kinds of combustible dust, combustible dust and combustible gas are easy to aggravate the explosion danger, so a set of dust removal system is adopted, and the dust removal systems in different fire zones are interconnected.

Article 2. Dry dust removal system has not taken one or more explosion-proof measures such as explosion venting, flame-proof, inerting, explosion suppression and explosion prevention.

Article 3. The dust removal system adopts gravity settling chamber for dust removal, or adopts dry tunnel structure as dust removal air duct.

Article 4. Negative pressure dust removal is not used in the dust removal system of metal dust such as aluminum and magnesium: when positive pressure dust blowing is used in other combustible dust removal systems, measures to prevent ignition sources such as spark detection and elimination are not standardized.

Article 5. For the processes that are easy to generate mechanical sparks such as crushing, grinding, granulating and sanding, measures such as removing sundries or detecting and eliminating sparks are not taken to prevent fire sources.

Sixth, the dust cleaning system was not formulated according to the specifications, and the dust on the job site and related equipment and facilities was not cleaned in time; The collection and storage of metal dust such as aluminum and magnesium have not implemented necessary explosion-proof measures such as waterproof, moisture-proof, ventilation and hydrogen monitoring.
