Unexploded Ordnance

Unexploded ordnance (commonly known as UXO, sometimes referred to as UXB) are explosive weapons (bombs, bullets, grenades etc.) that haven’t yet exploded and which still pose a risk of detonation. In the UK, the risk of encountering UXO is mainly limited to areas that suffered wartime bombing and to land used by the military for training or to store ammunition. These sites can pose risks to future construction and must therefore be investigated carefully.
