Describe the term "secondary ordnance" in relation to UXO.

The term "secondary ordnance" specifically refers to ordnance that may detonate as a result of contamination or when impacted by primary unexploded ordnance (UXO) during an explosion. In the context of UXO, this is a critical concept as secondary ordnance can create additional hazards beyond the initial threat posed by the unexploded devices. For instance, if UXO detonates and causes secondary ordnance to be detonated, it can lead to a more extensive explosion, increasing the danger to personnel and the environment.

Understanding this term is essential for safety protocols in dealing with UXO. It underscores the importance of careful assessment and monitoring of the area, as well as the need for appropriate safety measures to prevent triggering secondary ordnance. This distinction helps UXO specialists and teams to prepare for a range of possible explosive scenarios, ensuring a safer operation when dealing with such hazards.
