Chinese woman sawing out window openings - GIFs

Exposed blades, no visible eye or ear protection, long hair (as was mentioned earlier) — a piece of cardboard appears to be the only piece of PPE. OSHA wouldn't know where to begin. ("Are those steel-toed sneakers?") But they do manage to get things done. And, yes — that gal can swing a sledge. A regular 1-gal work crew.

Thanks, Hemmjo, glad to have that clarified. Hosie, I wonder how long that process took? If it’s one girl, she’s got 3 changes of clothing!

As Hoosiersmoker indicated, it looks like 4 clips from different job sites. However, I disagree with hemmjo's view, that concrete blades are inherently safe. A perfectly smooth disk, can grab loose clothing — especially hair — and ruin your whole day. Concrete saws have just enough bite to most assuredly grab hair and fabrics — and wrap you up in and around it. I doubt you'd survive many mistakes.

On another note, that appears to be a particularly fine aggregate and hard concrete/sand mix. Coring companies I've had occasion to rub elbows with are able to knock out some pretty big openings, in concrete walls, withing a day. Bank vault coring is generally smaller in size, but much thicker — and very hard, reinforced, concrete. But can likewise take a day, on average. The biggest delay, is probably figuring out who gets to pay, for getting locked out of the vault.

I will not argue this point, I agree you can get pulled in with loose clothing and long hair.

I do believe that these photos are however staged.
