You are Gus Gamelton. A member of Elevator Maintenance Team at Black Mesa Research Facilty. You work here for a very long time and alredy saw things. You heard that today a very important person visits BMRF but it's none of your business and today will be just another day, isn't it?
You know what might look awesome here?
How about adding tiny orange lights on the edges of the walk / drive way like on an airport. Mainly for forklift drivers so that they won't accidentally drive over the edge.
