During the previous two days, the company's colleagues had been assisted in installing a fireproof door, which they had returned to triangulate and share for information and communication。
Let's start with the word "extra"
At noon, he had a chat with the head of fire safety, who said that the fire brigade had come to check earlier, without a fine, and that the “drinking table” had been changed to a deadline. Leadership: "drink is a good thing, as long as you say it beautifully, you give each other a reason to drink, you're happy, you're happy, you're happy."
The joke is a joke, and the fire doors can be effective at critical times in halting the spread of fires, keeping them in the area of fire and buying valuable time for evacuation and fire rescue。

Why does the archives need fire doors
I came back to look at the rules and didn't find a separate mandatory provision for the "archive room" to install fire doors. It may be that there is a large amount of paper in the archives and that there is a high risk of fire, which is dealt with on the basis of “critical sites”。
