Dutch Explosives Unit Warns of Exposed Munitions Due to Low River Levels

The Dutch Explosives Ordnance Disposal (EOD) unit is issuing a warning about phosphorus grenades and other munitions that are becoming exposed as river levels drop significantly. These items pose a dual threat: they can easily ignite, and a subsequent explosive charge could detonate. The EOD advises anyone encountering such items not to touch them, to immediately call the police, and to leave the area. The police will then investigate and involve the EOD if necessary.

Recently, in Doornenburg near Nijmegen, fishermen encountered two grenades on a dried-out riverbank along the Waal. One was identified as a standard mortar shell, but the other contained phosphorus. Upon contact with the fishermen's cart, the phosphorus began to smoke and then ignited. The fishermen alerted emergency services, leading to the EOD's intervention to safely neutralize the grenade. While the explosive charge did not detonate in this instance, the EOD highlighted that such a possibility exists.

Phosphorus was added to much World War II-era ammunition, despite current international law prohibiting it, due to its ability to cause severe burns and create smoke screens. Post-war, large quantities of this ammunition were dumped into major rivers. Over eighty years later, the porous casings of these munitions are deteriorating, increasing the risk of accidental ignition or detonation upon contact. Despite the low water levels, the number of reported incidents remains relatively low, with only a few per week, though this is being monitored closely.
