|Edge protection: bund height markers
|At Baston Fen Quarry in Market Deeping, the problem of maintaining and checking safety bund heights has been overcome with some simple physical markers.
The minimum height markers, made by placing a tube in a 45-gallon drum and backfilling with rejected asphalt, are placed at regular intervals along the bund.
This is particularly important at Baston Fen, where lagoons exist on either side of a haul road. Should the bund level drop too low, the lagoons are in danger of flooding, potentially causing a road accident.
