What general safety precautions should be taken upon encountering a UXO?

When encountering an unexploded ordnance (UXO), the most appropriate course of action is to alert authorities and maintain a safe distance. This approach is vital for several reasons.

First, UXOs can be extremely dangerous as they are often unstable and may detonate if moved or improperly handled. By maintaining a safe distance, individuals minimize their risk of injury. Second, alerting the authorities ensures that trained professionals who possess the necessary skills and equipment can assess the situation safely and remove or deactivate the UXO.

The other options suggest moving closer for a better view or doing nothing and waiting, which does not prioritize safety. Moving closer could lead to an accidental detonation, while waiting without alerting the appropriate authorities leaves the UXO a potential threat to others nearby. Therefore, notifying the proper channels and keeping a safe distance is the only responsible action when encountering a UXO.
