Well that is good news and certainly better. I'm very surprised they didn't take it very seriously in the beginning especially with visible injuries. It probably didn't get to the right level.

Early in my career I was the "risk manger" (the insurance guy) for a Fortune 300. The amount personal injury claims we got (mostly frivolous) were substantial. The company had constructed its a large campus and almost 3 years to the day, a flood of personal injury suits came in (being the statue of limitations in NY). Waiting until memories are hazy and people turnover is a common ploy to force settlements.

Many were ridiculous and should have been covered by worker's comp or other parties but it didn't stop the lawyers from trying. A security guard got locked in while in the process of hiding & stealing PC's and had to jump to escape, getting hurt.

Not saying its right but it costs money to file, notify insurance companies, investigate, defend, etc even when nothing real or serious happened. That's why I'm surprised the OP wasn't placated while on site, again probably, the proper people weren't notified which is also a fail.
