Safety Precautions for Pre-stressing Operations

Date published: 26 August 2026

Topics: Mining and quarrying

It is important to consider the failure modes that may occur during the stressing operation. The strands of wire can be released due to the wire breaking at butt welds, at kinks in the wire, at damage points in the wire, failure of a double joiner, failure of wedges or barrels, failure of the anchorage points etc. The released wire moves at a very fast rate and can inflict serious or fatal injuries.
