So many issues here.

For starters, the use of bamboo scaffolding, a long tradition in China.

Then to cover the scaffolding and prevent ~things falling~ from hurting nearby people, the scaffolding was wrapped in a green mesh. That mesh should have been fire-resistant.

Also, to protect windows, a plastic foam was placed over them. Styrofoam or something like it. That also should have been fire-resistant.

There seems to be a question regarding the fire-resistance of those materials.

But my question, at this point, OK, so there may have been a fire on the outside of the building. Why did the fire seem to spread internally?

I remember my college dorm room. The wall between our room and the adjacent room was cinder block.

What are the building codes in the area regarding the prevention of fire spread within the building?
