The fire extinguishing agent itself is non-toxic and non-conductive, but when released, ensure that personnel evacuate promptly—within 30 seconds—to prevent carbon dioxide levels from becoming too high and causing suffocation.

  The features of high-pressure carbon dioxide fire suppression systems primarily include the following aspects:
  Principles of Fire Extinguishing
  It primarily relies on the heat absorption and cooling effect, as well as the reduction of oxygen concentration achieved during carbon dioxide gasification, to achieve smothering fire suppression, delivering both cooling and asphyxiation effects.
  Storage Characteristics
  Using high-pressure liquid storage (typically stored at 5.17 MPa), a dedicated storage room is required, and the storage room must have sufficient structural strength as well as measures to prevent direct sunlight exposure.
  Security
  The fire suppressant itself is non-toxic and non-conductive, but when released, personnel must evacuate promptly—within 30 seconds—to prevent carbon dioxide levels from becoming too high and causing suffocation.
  Scope of Application
  Suitable for electrical fires, flammable liquid fires, solid-surface fires, and certain deep-seated fires (such as those involving cotton, linen, wool fabrics, or paper), but not applicable to fires involving oxidizers (like nitrocellulose) or reactive metals (such as potassium or sodium).
  Economic efficiency
  The fire extinguishing agent is low-cost, and the system requires minimal daily maintenance, making it ideal for locations that need frequent activation.
