NFPA 12, Standard on Carbon Dioxide Extinguishing Systems

This standard sets out the performance requirements for emergency and standby power systems that provide an alternative electrical power source in buildings and facilities when the usual power source stops working. These systems include power sources, transfer devices, control systems, monitoring equipment, and other necessary components that help deliver electricity to the designated circuits.

To design, install, and maintain these systems safely and effectively, it’s important to stay current with the latest information on carbon dioxide (CO2) fire extinguishing systems.

NFPA 12, the standard for CO2 extinguishing systems, covers all types of CO2 systems used in industrial and marine fire protection.

This includes total flooding systems, local application systems, hand hose line systems, standpipe systems, and mobile supply systems.

This standard offers the most up-to-date consensus guidelines for designing, installing, and maintaining both high-pressure and low-pressure CO2 extinguishing systems.
It also keeps pace with the code references from NFPA 4, the standard for testing integrated fire protection and life safety systems.

This information is crucial for engineers, facility managers, inspectors, and fire protection designers and installers.
