is a fixed point of reference used to locate a marked and recorded hazard or hazardous area. It should normally be located a short distance outside the hazardous area. It should be safe to walk from the Reference / Landmark to the Benchmark.

Note: {{note| A benchmark may not be necessary if the reference point / landmark is sufficiently close to the perimeter of the hazardous area.}}
