The article above is written from a terribly biased view. As someone said, accidents can happen anywhere.
I know the workers are less experienced but they are very strongly motivated to do it , they love doing so. It is certainly not “guilt”. I met a dub the other day who is going abroad on a build . The comradery and fun is amazing .
I am sorry for the “sister” who was injured but note that she wanted to straight back.
I do hope though that safety is a first responsibility of those planning it.
