Copyright © 2007 National Fire Protection Association®. All Rights Reserved. This edition of NFPA 2001, Standard on Clean Agent Fire Extinguishing Systems, was prepared by the Technical Committee on Gaseous Fire Extinguishing Systems and acted on by NFPA at its June Association Technical Meeting held June 3–7, 2007, in Boston, MA. It was issued by the Standards Council on July 26, 2007, with an effective date of August 15, 2007, and supersedes all previous editions. This edition of NFPA 2001 was approved as an American National Standard on August 15, 2007. Origin and Development of NFPA 2001 The Technical Committee on Halon Alternative Protection Options was organized in 1991 and immediately started work to address the new total flooding clean agents that were being developed to replace Halon 1301. A need existed for an explanation of how to design, install, maintain, and operate systems using these new clean agents, and NFPA 2001 was established to address this need. The 1994 edition was the first edition of NFPA 2001. This standard was revised in 1996, 2000, and 2004. In January 2005, the technical committees responsible for NFPA 12, NFPA 12A, and NFPA 2001 were combined into the Technical Committee on Gaseous Fire Extinguishing Systems to better address and resolve issues among those documents. This action is intended to facilitate correlation and consistency as requested by the U.S. Environmental Protection Agency. The 2008 edition has added requirements for local application systems.

protected surface. 6.5.4* Nozzles shall be located so as to be free of possible obstructions that could interfere with the proper projection of the discharged agent. 6.6* Operation. The system shall be designed for automatic operation except where the authority having jurisdiction permits manual operation.
Chapter 7 Inspection, Testing, Maintenance, and Training 7.1 Inspection and Tests. 7.1.1 At least annually, all systems shall be thoroughly inspected and tested for proper operation by personnel qualified in the installation and testing of clean agent extinguishing systems. Discharge tests shall not be required. 7.1.2 The inspection report with recommendations shall be filed with the owner of the system. 7.1.3 At least semiannually, the agent quantity and pressure of refillable containers shall be checked. 7.1.3.1 For halocarbon clean agents, if a container shows a loss in agent quantity of more than 5 percent or a loss in pressure (adjusted for temperature) of more than 10 percent, it shall be refilled or replaced. 7.1.3.2 For inert gas clean agents that are not liquefied, pressure is an indication of agent quantity. If an inert gas clean agent container shows a loss in pressure (adjusted for temperature) of more than 5 percent, it shall be refilled or replaced. Where container pressure gauges are used for this purpose, they shall be compared to a separate calibrated device at least annually. 7.1.3.3 Where the amount of agent in the container is determined by special measuring devices, these devices shall be listed. 7.1.4* All halocarbon clean agent removed from refillable containers during service or maintenance procedures shall be collected and recycled or disposed of in an environmentally sound manner and in accordance with existing laws and regulations. 7.1.5 Factory-charged, nonrefillable containers that do not have a means of pressure indication shall have the agent quantity checked at least semiannually. If a container shows a loss in agent quantity of more than 5 percent, it shall be replaced. All factory-charged, nonrefillable containers removed from useful service shall be returned for recycling of the agent or disposed of in an environmentally sound manner and in accordance with existing laws and regulations. 7.1.6 For halocarbon clean agents, the date of inspection, gross weight of cylinder plus agent Copyright NFPA
