2018 Edition

Get a clearer picture on clean agent systems with the 2018 edition of NFPA 2001.

Everyone responsible for fire protection of IT/telecommunications equipment, high value assets, or marine vessels needs NFPA 2001, Standard on Clean Agent Extinguishing Systems to keep pace with the latest design and maintenance requirements plus complete facts on the different types of halogenated and inert gas extinguishing agents in use today.

Now featuring a reorganized, more user-friendly format, the 2018 edition of NFPA 2001 has essential requirements on how to properly purchase, design, install, test, inspect, approve, operate, and maintain engineered or pre-engineered gaseous agent fire suppression systems so they will function as intended when needed.

Revisions in the 2018 edition of NFPA 2001 help improve safety and reliability.

• Separate chapters on Installation Acceptance and Inspection, Servicing, Testing, Maintenance, and Training better define the application of inspection and testing requirements to new and existing systems.
• Integrated fire protection and life safety system testing must be conducted in accordance with NFPA 4, Standard for Integrated Fire Protection and Life Safety System Testing.
• An egress time study is required for all clean agent systems, not just those where the design concentration is greater than the no observable adverse effects level (NOAEL).
• Dirt traps must be installed at the end of each pipe run.

Other changes include:

• Updated requirements for pipe and fittings
• A new section on pipe hangers and supports
• New requirements regarding releasing panels
• New and updated definitions

A must for building or marine vessel owners, installers, maintainers, manufacturers, and AHJs.

2015 Edition

Reference the 2015 NFPA 2001 for more economical and environmentally friendly fire protection using clean agent systems.

Expanded with new coverage about environmental safety and new types of systems in use today, NFPA 2001, Standard on Clean Agent Extinguishing Systems provides essential requirements on how to properly purchase, design, install, test, inspect, approve, operate, and maintain engineered or pre-engineered gaseous agent fire suppression systems so they will function as intended when needed.

Changes in the 2015 NFPA 2001 address environmental safety, acceptance testing, and new equipment:

• NFPA 2001 now permits the use of recycled agent and sets quality standards, so installers and system owners can recharge systems more economically while reducing emission to limit environmental risks. This new coverage also gives the Authority Having Jurisdiction (AHJ) a clear set of guidelines for system approval.
• First-time coverage on how to dispose of recovered agent and reduce or eliminate non-fire-related emissions of the halocarbon agents offers greater environmental protection.
• A new acceptance report for compliance with NFPA 3, Commissioning of Fire Protection and Life Safety Systems assists building owners, contractors, and AHJs as they work to comply with the commissioning process,
• Added support data and fitting requirements for 200-bar and 300-bar IG-01 (nitrogen) systems makes it easier to use new types of systems.

Building owners, installers, maintainers, manufacturers, and AHJs will get a clearer picture on clean agent systems.

Everyone responsible for fire protection of IT/telecommunications equipment, high value assets, or marine vessels needs the 2015 NFPA 2001 to keep pace with the latest toxicity limitations plus complete facts on the different types of halogenated and inert extinguishing agents.
