There's been building work going on at our office building ever since I started. It's been dusty and noisy and I've cursed it under my breath several times (and I'm not the only one). Today, they put up some scaffolding outside the windows of my section, and then some builders came, in safety harnesses, and started doing whatever it was they needed the scaffolding for.
At one point I looked up and noticed one of the men wasn't wearing a safety harness. I didn't think anything of it, though; I just went back to work. Next thing I hear is this screech and an awful thud.
The three of us in our section sat bold upright, looking at each other uncertainly and going "Was that...?" "That sounded like..."
The ambulance was there in under 6 minutes. The man was still alive, but he'd fallen 3 storeys and landed on his head, or so the shocked security guard came and told us.
I hope he makes it.
