If you, as a property owner, find explosive ordnance on your property, you must immediately report this to the competent security authority or the police, otherwise you will expose yourself and other people to a high risk.

Explosive ordnance includes all ammunition or parts of ammunition intended for warfare which is explosive by nature, in particular rifle cartridges, bombs, mines, grenades, explosives and detonators.

Often ordnance is not recognizable as such. Many are rusted beyond recognition or resemble commercially available objects in appearance. The obligation to report also applies to walkers who find ammunition.
