【 摘 要 】

During building fires is often necessary to deliver nozzles with water to the desiredpoint of intervention and the wall or ceiling must be penetrated for energy supply andthe entrance of persons. Access openings for extinguishing are created with hand tools orexplosives, but it is a very time-consuming activity and fragmented material may endangerpersons. Another possibility is the use of charges with a water layer, which absorbsthe shock wave of the explosion at the back and at the same time significantly suppressesthe fragmentation of the building element on which the charge acts. The penetrationcharge developed in two versions allows a sufficient penetration of the partition wall.
