The visible information is that the fact that they WANT to demolish something and that it might potentially be dangerous to walk on the roof, hence the fences. The invisible information you can derive is that there must be dangerous materials they used in building this structure. The gas masks with complete covering suits indicate a high probability of asbestos. This also gives us the additional information that indeed the building must be old since we don't use asbestos anymore (for good reasons). We nowadays know that asbestos is bad for your health, so we can see that we now use a lot of care to clean it up. To make the urban living better we don't use these kind of dangerous materials anymore and take good care in choosing our materials before building to make sure they will not cause the same disasters as were seen with asbestos.
