A World War II-era white phosphorus grenade was safely neutralised in Luxembourg last week after civilians discovered it and followed safety protocols, which prompted a specialised response from the Luxembourg Army.
Specifically, the civilians came across a US rifle grenade containing white phosphorus.
White phosphorus, often abbreviated as “WP” in military contexts, is a substance that ignites spontaneously upon contact with air and continues to burn as long as it is exposed to oxygen. It produces a thick, toxic white smoke that is not only highly irritating but can also cause serious burns upon contact with skin.
These types of grenades typically have a thin casing and are triggered by an internal explosive charge. Even after lying dormant in the ground for decades, such munitions can remain unstable and extremely dangerous.
Authorities stress that under no circumstances should anyone attempt to touch or move such munitions if discovered. The area should be evacuated immediately, ideally maintaining a minimum distance of 100 metres. The police or army should then be contacted.
Extra caution is advised if there are active signs of reaction, such as the release of smoke or a corrosive odour.
In this particular case, the individuals involved acted in an exemplary manner, helping to ensure that no one was injured and that the grenade could be safely neutralised.
