Some companies take the initiative to lower workers comp claims and work to get rid of trip hazards while others seem to enjoy having junk laying all over to trip on. I don't enjoying tripping at work, at home, or anywhere else. I sure don't enjoy seeing the elderly trip on a hitch and eat the pavement in a stores parking lot.
I'd like to offer a little perspective on some of the issues you have touched on.
In a commercial audio environment I have worked the past 20 years in many different locations. Bars, restaurants, concert venue's, outdoor areenas, streetside locations during outdoor festivals.. etc.
In that time i have seen the following trip / fall situations ( and I see at -least- 1 trip / fall per week - yes, no joke! )
stepping up onto a curb, or off a curb onto pavement. This is the single most cause of trip fall i have ever seen at all my venue's. I see it up to 3 times a month easy.
the last step on a stairwell before a flat landing. People miss that step then fall. This one is the NEXT most common after falling at a curb. I see at least 1 per month.. sometimes 2.
spontanious falling while dancing. Yup. I'll be setting their in a sound mix position at the front of house, people dancing. and then a hole forms and someone goes down. This is another at least 1 per month thing.
Lastly, when we run cables over areas that there is foot traffic ( or car traffic ). we use cable troughs .. commonly called bumble bee's. these are black / yellow striped, have 2 sloped sides and a trough area about 1" deep for cables. they are about 8: to 10" wide, they are approved for wheel chair and walkers to go over due to the angled approach , they have a positive traction surface and raised traction to reduce slippage if wet. They have 2 primary purposes. 1, prevent cable damage... 2, prevent trip hazard.
Yep. I have seen people trip while walking over the thing that keeps them from tripping!
What I have not. ever seen..

and I'm being truthfull here.
I've never seen a trip over the tounge of a parked equipment trailer ( and we use many, many equipment trailers! ) Or the drawbar on the back of the trucks that pull those trailers, and no. I don't know a single guy on the crew that removes them, as we pull a trailer 2x per day usually.
This includes massive parking areas, the venue locations, party areas.. etc.
All the injury reports go thru management and at all outdoor locations we usually have an EMS tent or a fire rescue or ambulance vehicle on site. At indoor locations, EMS is called if a patron requests it, or unable to request it, and usually if there is blood.
Apparently stepping 'up or down' IE. lifting your feet is the big issue here.
