Confined Space Silo Cleaning

Confined Space Silo Cleaning using Rope Access

We were contacted by one o our long term clients to carry out some unsociable hours cleaning to a number of silo.

Risk & Method Statement were agreed along with a Safe System Of Work.

The work brief entailed entering the silo via the access hatch at the top, abseiling down the inside and de-contaminating the roof and walls and cone of the silo.

Due to the cones being fixed at the base of the silo.....and only a small hole for the excess product to be extracted from, we had to use a rescue winch which was attached to the entrant in case a rescue was warranted......we regularly practice mock rescues using this system.

Prior to entry a Peak Atmospheric reading is taken by lowering a 4 gas air monitor into the silo, once the readings are satisfactory then entry can be undertaken, our entrants all wear 4 gas air monitors whilst working in  Confined Space conditions  ......recording readings from the 4 gas air monitors every 5 minutes, these reading should be kept on file and handed over to the next company that carries out works in the confined space.
