Establishing and working in and at excavations can be a dangerous affair. There may be a collapse of soil in the excavation, and there may be a collapse into the excavation itself – either of personnel or material.
It is therefore important that you prepare well and constantly keep an eye on what need there is for securing the excavation, what need there is to block against driving traffic, where machines, tools, piles of dirt, etc. are placed. The following can hopefully be used as a checklist:
For all depths, tasks and the like, the following applies:
Proper access roads and escape routes to excavations must be established.
Ladders can be used as an escape route. Place it close to the work area. The ladder must stand on a stable surface AND protrude 1 meter above the edge of the excavation.
In the case of a construction pit, a permanent access road in the form of a staircase must be established. There are special requirements for such a staircase. If necessary, see “Manual – Working environment for building and construction”.
When working and driving above excavations, a secure railing must be set up around the entire excavation at a height of at least 1 meter.
Some excavations may be wider at the top than at the bottom, and therefore there may be an opening between e.g. the trench box and terrain. Solution: Fill up with soil or establish railings and access road.
Cranes, excavators and trucks are often used close to excavations. Solution: The surface must be stable and tread plates can be laid.
