Seeking assistance in determining the fire hazard classification for workshops with explosive dusts
Thread Content
I was previously exposed to workshops with explosive gases (such as hydrogenation workshops), whose fire hazard category is classified as Class A. Today I suddenly wondered: how should the fire hazard category of workshops with explosive dusts be determined? (For example, in a flour processing plant, the flour itself is classified as Category C at most, but flour particles suspended in the air can explode when exposed to a fire source. ) I’m a bit confused; please advise me, experts
Fire protection is about fire prevention, and explosion protection is about preventing explosions. For fire protection, one needs to refer to building codes and petrochemical industry regulations; for explosion protection, electrical-related standards must be considered
The fire hazard of explosive dusts is classified as Category B; flour storage warehouses are classified as Category C, while workplaces where flour is suspended in the air are classified as Category B.
Thank you, I took a close look at the specifications and indeed it’s like that.
