history: The building where I work is under construction and senior leadership was recently offering tours to staff members. I was a little nervous about having to walk through a live construction zone and thought I might trip on something.  I work in a building that has parts of it under construction and our senior staff is offering tours. I'm a little worried about tripping and falling on something if I take a tour through the live construction zone.  I can certainly relate to you_comma_ it could be a safety hazard.
current: I agree! I think if I do it, i need to buy some closed-toe shoes and make sure I'm wearing the correct clothing. 
next: That's a smart move, that would reduce the risk of injury.
