ABSTRACT:
A safety net attached to the doors at a pumping station to cover the open well when the doors are open. The safety net has a plurality of strips in a first direction and a substantially perpendicular plurality of strips in a second direction. The strips are connected where there are intersections. The edges of the strips have attachment means for connection to the doors, or alternately for connection to the frame about the top of the well. When the doors are opened, the safety net is in place and when the doors are closed, the safety net is suspended in the open well. The safety net may also be connected to a single door for those wells which have only a single door as a cover.
