I am on about another cleaner being injured at work.
  when he left for work in the morning he never thought he would end his day in hospital.
  regardless of this it could affect you in the future we  all  learn from others mistakes and misfortunes.
  if all you can do is take the  micky just hope it isn't you  next time.
think of the human angle for once and try to show some  a little compassion and sympathy  three weeks in hospital   not knowing  what psychological damage or long term ill effects the poor man has suffered.
that's what I am on about

No-one has been injured. 
As Hozier says: "that's a fine looking high horse"

But it wasn't cleaning solar panels that he was injured.
