Preformed concrete barriers, bollards, or other physical barriers should be installed in such a fashion that if the barriers are impacted and knocked over, they will not strike the well head.

High visibility flags should be extended above the well head to a height that will able to be seen by mechanical equipment operators. Flags will be mounted to poles.

Blinking lights should be included on the flagpoles at night for additional visibility.
