Anyone who cleaned commercials before wfp came along, and before there was such a thing as a "Facilities Manager", will have got up to stuff like this. And, as you can see, it still happens today.
The person MOST to blame here will be the person in charge of the office he's cleaning - or the owner of the building - because you can bet your bottom dollar that when they got a flyer from the firm who install safety bolts, it got binned because it would have cost too much to install. Ooh, wafered poles, what are they? Hmm, sounds good, much safer you say? The street's going to be closed because you need to stand in the road to get to these windows? Never darken my door again, you reprobate!
If the guy was wearing a harness, would anyone have bothered? NO!
If he was walking a ledge on the ground floor, would anyone have bothered? NO!
Want to bet the daft laddie gets a bigger telling-off from HSE than the office manager who's going to get it in the neck for letting him work like that? NO!
How long do you think the job's been done like that if there's no safety anchors? From whenever the building was built, of course. Why has it just come to light now? Because somebody who should have been concentrating on their own work in the office opposite was bored, and decided to play with the camera on his mobile phone.
Oooh, I'm off for a lie-down.
