The ordinary anti-theft door with a price of more than 500 yuan, a little fireproof cotton was inserted in the cat's eyes, and it turned into a "fire door" of more than 800 yuan. During the fire safety random inspection of a certain district, it was found that many entrance doors had substandard phenomena. Upon further inspection, they were surprised to find that there were actually 236 "fire doors" in the community that were "transformed" by security doors. At present, the fire department has filed a case for this matter, requiring replacement of unqualified "fire doors", and will jointly investigate and deal with dealers.

 

The "fire door" is filled with flammable honeycomb paper

 

Fire doors, as the name suggests, have the function of isolating soot, preventing the spread of fire, and protecting people's lives and property. But in order to make more money and make more money, illegal merchants risk the lives of the people. "When we inspected the buildings in this residential area, we found that many entrance doors were unqualified." Therefore, law enforcement officers took the demolition tools and called the construction unit, supervision unit and dealers. "For further inspection.

 

After removing the "cat's eye" on the door, only yellow cotton-like substance was exposed from the hole. After pulling out a small part, sticking fingers into the hole, law enforcement officers found that the filling material inside the door was cardboard. Later, law enforcement officers demolished it-the so-called "fire door" was all flammable honeycomb cardboard. The law enforcement officer lit it with a lighter and immediately burned it. "Fire doors have strict requirements on the selection, production, and installation of materials." Law enforcement officers at the scene told reporters that qualified fire doors have fire plywood, expansion seals and other components. The internal filling materials are all fire materials. This batch of " "Fire doors" are clearly problematic.

 

"Fire door" does not fire, where does the certificate come from?

 

This batch of unqualified "fire doors" has related certificates, so what's the problem? After inspection, it was found that a total of 236 "fire doors" were posing as ordinary security doors. In front of the evidence, the dealer Zhu had to acknowledge the fact that he manufactured and sold counterfeit "fire doors" and explained the source of the certificate.

 

It turned out that Zhu first contacted the manufacturer and said that relevant fire door materials were needed for bidding. After obtaining the type approval certificate and inspection report, Zhu told the manufacturer that he had not won the bid, but entered a batch of ordinary security doors to the manufacturer. After a little fireproof cotton was stuffed around the "cat's eyes" of these security doors, Zhu took the certificate and sold the door to the developer to cheat the high price difference. "The purchase price of the security door is only over 500 yuan. When the fire door is sold, it is more than 800 yuan."

 

How to identify real and fake fire doors

 

According to reports, the quality and role of fire doors cannot be ignored. In recent years, because fire doors do not meet the requirements and fail to perform fire protection, there have been many cases of fire accidents causing mass deaths and injuries, and the lessons are painful.

 

So how to identify true and false? The reporter learned that it is not difficult to distinguish the authenticity of the fire door. You can remove the "cat's eye" and put your hand into the hole to test the internal filling. You can also see whether the door frame has an "expansion seal" . In addition, it can also knock the door. Regular fire doors are generally heavier than ordinary steel doors, and there is no hollow sound when knocked.
