Oxygen (O₂) and Air Supply Systems for Shelters: Compressed Air, Overpressure Control and Emergency Oxygen Generation
Introduction Maintaining suitable atmospheric conditions is an important part of operating shelters designed to remain isolated from the external environment. According to Atmas Group, shelters operating in complete isolation mode (“lock-up mode”) for extended periods require air-regeneration systems to help maintain safe levels of carbon dioxide (CO₂) and oxygen (O₂), as well as positive internal pressure. Atmas Group offers oxygen and air supply solutions, alongside systems

Continuous or portable measurement allows radiation levels to be detected and monitored in environments where exposure risks may require timely assessment. According to Atmas Group, its radiation detection portfolio includes fixed, transportable and handheld radiation detection and monitoring devices, as well as complete solutions for per
Rebound and Negative Pressure: What Happens to a Blast Door After the Initial Impact?
Explore how outward-opening shelter blast doors respond to initial pressure, rebound, and negative-phase loading, and why door construction, support conditions, and the basis of specified reverse loads matter.
Prefabricated Concrete Shelters and Bunkers: Modular Protective Structures
Prefabricated concrete shelters and bunkers provide a modular approach to creating protected spaces using pre-designed concrete precast modules and components. Atmas Group presents these solutions for both on-the-ground and underground applications, with configurations ranging from compact shelters to larger protective structures. Atmas Group The use of prefabricated elements allows protective structures to be developed according to the required application, capacity and pro
CBRN Filtration and Protective Shelter Technologies: Engineering, Equipment and Practical Demonstration
Modern civil defence shelters require an integrated approach to protection. In addition to the physical structure, protected facilities may incorporate CBRN air filtration, emergency ventilation, blast and overpressure valves, gas-tight components and other air-management systems. Atmas Group provides technologies and solutions for civil defence shelters, bunkers, safe rooms and other protected facilities, including CBRN filtration and ventilation systems, blast valves, overp

The Good Bunker is a modular underground shelter solution developed around prefabricated polypropylene modules that serve as the permanent watertight shell and formwork for reinforced concrete protective structures. According to the manufacturer, the system is designed for underground bunkers covered with concrete and/or earth
CBRN Filtration, Ventilation and Air Management in Civil Defence Shelters
Modern civil defence shelters require more than structural protection. A protected facility also needs engineered systems for ventilation, air filtration, pressure control and the management of potentially contaminated air. Atmas Group provides solutions covering these areas, including CBRN/NBC filtration systems, ventilation equipment, blast valves, overpressure valves and CO₂/CO filtration systems. Atmas Group — CBRN / NBC Filtration Systems CBRN filtration CBRN refers to C

Practical Observations on Shelter Access, Protection, Daily Use, and Long-Term Readiness
The war in Ukraine has highlighted many civil-defense questions. Repeated attacks on cities, frequent air-raid alerts, and disruptions to essential services have shown how much shelter performance relies on decisions made before an emergency occurs. Structural strength is critical, but timely access to protection is equally important. People must be able to enter shelters quickly, remain inside under acceptable conditions, and, in some cases, continue essential work. Electric
