NFPA12

Stay informed on the latest carbon dioxide (CO2) fire extinguishing systems for safer and more efficient design, installation, and maintenance.

Coverage in NFPA 12, Standard on Carbon Dioxide Extinguishing Systems, addresses carbon dioxide total flooding systems, local application systems, hand hose line systems, standpipe systems, and mobile supplies for the full range of systems used for industrial and marine fire protection.

Up to date with code references in NFPA 4, Standard for Integrated Fire Protection and Life Safety System Testing, this standard presents the latest consensus-based rules for the design, installation, and maintenance of both high-pressure and low-pressure CO2 extinguishing systems and is essential for fire protection designers and installers, engineers, facility managers, and inspectors.

Updates to the 2025 edition of NFPA 12, Standard on Carbon Dioxide Extinguishing Systems, include:

  • A new table for extended discharge for enclosed recirculating, rotating electrical equipment
  • Added provisions to assist the user in calculating times for values not covered by the document
