At approximately 10:30pm, the contractor was carrying a sheet cake along a sidewalk. Approximately 25 feet East of the kitchen entrance, a sump pump drain pipe had been installed across the sidewalk, at an earlier date. The contractor did not see the pipe and tripped over it.
Consider proper placement of drain lines or any other line to prevent trip hazards.
The person walking should keep eyes on path and be aware of his/her suroundings.
