It's scaffolding. Stop being a noob Alex. Why do you need to know? Unless you are going there in which case you can see for yourself. They obviously think it's fine because they use it themselves on a regular basis.
Strange question, it would be useful to know why you need this information. My answer would be a little bit more dangerous than in Europe or North America because worker safety laws are often not enforced. So I would decide how many points you would give the U.S. or Europe and subtract 1-2 points as compared to the U.S. and 1.5-3 points as compared to Europe.
Hi there, from what I have seen I would give it a 5 on a scale 1-10, not very safe.
Are you seriously asking that question?
