During my career, I have come across several types of wet system door openers used to open high-security doors in military and law enforcement applications. However, the solutions have been developed for specific types and security levels, which greatly limits the possibilities of their application. Even though such charges are made up of either ad hoc or standard elements, I still believe that changes could be made to the current designs. One of my goals for the near future is to investigate and create a liquid-filled filling chamber that is designed to open a variety of security-rated doors and windows. The necessity of this is that the physical protection capabilities of critical infrastructures are very different from those generally used and the challenges of opening them by blasting are known to few. In my study I will try to summarize international progress in the field of blasting and to outline new possible solutions in this area.
