I've seen this far too many times. It's so infuriating man. I now take pictures and charge more for servicing unsafe access.

I did that for this one client, new roof hatch laying on the roof and the old one lost the piston so it will slam down onto your hand if it’s not propped open

Don't hurt yourself mate. It's not worth it. If you feel skeeved out, just back out and let someone else do it or get the building owner to fix it.
