There is much much more than what is shown in this video. There is a lot and it varies in color from white to grey. Consider that asbestos was used for pretty much everything when this block was built. The percentage of asbestos used is unknown in the different materials, but I can guarantee that there is asbestos here in at least some of this, or more likely all of it. Even if the asbestos percentage is low (which I doubt it is) just smashing the internal walls of the flats like this is the worst possible way to remove it. Dust from everything would go everywhere, and just using an asbestos mask won’t be enough to protect you.
I feel sorry for the poor workers who were forced to do this.
