NFPA 12, Standard on Carbon Dioxide Extinguishing Systems, 2025 Edition Paperback

This standard covers performance requirements for emergency and standby power systems providing an alternate source of electrical power in buildings and facilities in the event that the normal electrical power source fails. Systems include power sources, transfer equipment, controls, supervisory equipment, and accessory equipment needed to supply electrical power to the selected circuits.

To ensure safer and more effective design, installation, and maintenance, it’s important to keep up with the latest information on carbon dioxide (CO2) fire extinguishing systems. NFPA 12, the Standard on Carbon Dioxide Extinguishing Systems, covers all types of CO2 systems used in industrial and marine fire protection, including total flooding systems, local application systems, hand hose line systems, standpipe systems, and mobile supply systems.

This standard provides the most recent consensus-based guidelines for designing, installing, and maintaining both high-pressure and low-pressure CO2 extinguishing systems. It also stays updated with the code references from NFPA 4, the Standard for Integrated Fire Protection and Life Safety System Testing. This information is essential for engineers, facility managers, inspectors, and fire protection designers and installers.
