How is the electrical explosion protection rating of a certain factory building determined step by step?

1. How is the electrical explosion protection rating for a certain factory building determined step by step in a correct manner? 2. How is the electrical explosion protection rating for a certain tank storage area determined step by step in a correct manner? Is it first necessary to determine the fire hazard level based on the properties of the substances, then for the electrical engineering team to determine the explosion-proof zones considering factors such as ventilation, and finally to determine the explosion protection rating based on the burning temperature of the substances? ?
That’s more or less the idea: hazard zones are classified based on the properties of explosive gases, as well as their frequency of occurrence and duration of presence, and then the explosion-proof rating of electrical equipment is determined. It is recommended to consult GB50058, Code for Design of Electrical Installations in Explosive Atmospheres
First, learn the *standards thoroughly; then, hand in hand, take one step, two steps, three steps, four steps, looking up at the sky to see the stars – one star, two stars, three stars, four stars, forming a line.
If I’m not mistaken, the original poster is from Zibo.
Search for \"explosion protection rating\" on Baidu; there are detailed explanations available
Haha, there are tons of design institutes in Zibo
