Resumen de Managing Health & Safety Risks: No. 61: Unexploded ordnance

The Institution of Structural Engineers' Health and Safety Panel

• Unexploded ordnance (UXO) is explosive weaponry (bombs, shells, grenades, land mines, naval mines, cluster munitions, etc.) that did not explode when it was employed and still poses a risk of detonation, sometimes many decades after it was used or discarded. Such items are unearthed fairly regularly on building sites both in the UK and worldwide.
