What was the status of us workplace safety laws in 1900?

Absolutely horrendous. There were no Child labor laws, meaning that children would face practical slave labor and unsafe conditions while working in factories. The machines in these factories were anything but safe, and it was not uncommon for someone to lose a finger, and/or die due to an affect of the machine. There were almost no laws in place at this time to change this.  

You don’t have to names or other options up here so idk dude
