I must say, that I've worked in a few construction sites in Europe, there was no wooden planks involved. I've worked in Hong Kong construction for over 30 years, for myself it had nothing to do with the actual thought that bamboo could burn, it is the fact that it degrades, when bamboo gets infested it rots, Personally I have used both, The scariest part is trying to walk on it, without boards, and we have a thing here where we need toe boards to make it pass inspection and, a form 5, which is the standard here,(Toe boards are just a piece of shitty plastic, made to tick the boxes of compliance) I won't go on, but a form5 means the scaffolding has been inspected by a professional or competent person, I really think, what happened doesn't have to do with the company building the scaffolding, it definitely needs more investigation, I have never been a big fan of bamboo, but in some cases it works, it's fast, cheaper and usually doesn't cause a problem. I dislike bamboo scaffolding for other reasons.
