surely there should have been more than 1 person doing that job?
If there wasn't then for whatever reason that needs looking into and resolving in the future. I have a family business that deals with transporting heavy equipment. Even if it is just smaller items like 10 6ft tables that are being sent, which could be managed by a single person, for safety two people are sent.
I'm not saying this is a fault of the poor lady and i want to stress that as i do not want it misconstrued but i hope that this incident leads to greater health and safety considerations by the company in general. It's not the first dodgy thing I've seen from DF.
My deepest condolences to the friends and family of the woman. No one should have to endure the pain this will inevitably cause for everyone involved.
