NFPA 2 Overview Susan Bershad, Staff Liaison, NFPA Overview Who are we? What is NFPA 2? What does it cover? What has changed? nfpa.org2 Who is NFPA? Founded in 1896 Independent Mission Driven Not-for-profit (501(c)(3)) Membership Organization over 60,000 members Members in 118 Nations 11 Membership Sections Voluntary Codes & Standards Developer (SDO) ANSI Accredited Organization International Recognition (ISDO) nfpa.org3 Who is NFPA and What does NFPA do? Mission: We help saves lives and reduce loss with information, knowledge, and passion. Vision: We are the leading global advocate for the elimination of death, injury, property and economic loss due to fire, electrical and related hazards. nfpa.org4 Code Development Process Codes and Standards development through consensus process Technical Committees develop documents through public input and comment process Balanced committee makeup no more than one-third from each member category nfpa.org5 Code Adoption Code must be adopted to be enforceable Authority having jurisdiction (AHJ) enforces fire code. AHJ can be local fire department, state fire marshall, insurance company AHJ role is to review and approve installation and modifications. nfpa.org6 California Adoption 2013 California Fire Code references NFPA 55 for setback distances from storage California has adopted the 2011 edition of NFPA 2. State Fire Marshall action edition was issued June 15 th, Adoption of the 2016 edition is in progress nfpa.org7 Need for a National Hydrogen Code With the increased interest in hydrogen being used as a vehicle fuel source, the NFPA was petitioned to develop an all-encompassing document that established the necessary requirements for hydrogen technologies Technical committee formed in 2006 Focus is to address all aspects of hydrogen, storage, use and handling Draws from existing codes and standards Identifies and fills technical gaps for a complete functional set of requirements Developed for code users and enforcers Structured so that it works seamlessly with building and fire codes. nfpa.org8 Purpose of NFPA 2 The purpose of this code shall be to provide fundamental safeguards for the generation, installation, storage, piping, use and handling of hydrogen in compressed gas (GH 2 ) form or cryogenic liquid (LH 2 ) form. nfpa.org Application This shall apply to the production, storage, transfer and use of hydrogen in all occupancies and on all premises The use of hydrogen shall include stationary, portable, and vehicular infrastructure applications. The fundamental requirements of Chapters 1 through 8 shall apply in addition to the use-specific requirements provided in Chapters 9 through 20, as applicable nfpa.org Exemption Onboard vehicle or mobile equipment components or systems including the onboard GH 2 or LH 2 fuel supply Mixtures of GH 2 and other gases with a hydrogen concentration of less than 95 percent by volume when in accordance with NFPA 55, Compressed Gasses and Cryogenic Fluids Code. The storage, handling, use, or processing of metal hydride storage systems defined in Chapter 3 This code shall not apply to the following nfpa.org Equivalency Nothing in this code is intended to prevent the use of systems, methods or devices of equivalent or superior quality, strength, fire resistance, effectiveness, durability and safety over those prescribed by this code. nfpa.org Retroactivity NFPA 2 does not apply retroactively unless authority having jurisdiction determines that a distinct and identifiable hazard exists. nfpa.org NFPA Administration 2.Referenced Publications 3.Definitions 4.General Fire Safety Requirements 5.Performance-Based Option 6.General Hydrogen Requirements 7.Gaseous Hydrogen 8.Liquefied Hydrogen 9.Explosion Protection (reserved) 10.GH 2 Vehicle Fueling Facilities 11.LH 2 Fueling Facilities 12.Hydrogen Fuel Cell Power Systems 13.Hydrogen Generation Systems 14.Combustion Applications 15.Special Atmosphere Applications 16.Laboratory Operations 17.Parking Garages 18.Repair Garages Chapter 4 General Fire Safety Requirements Objectives Compliance Options Emergency Plans Prohibited Releases Personnel Training Ignition Source Controls Signage Protection from Vehicular Damage. nfpa.org15 Chapter 6 General Hydrogen Requirements Concept of MAQ (Maximum Allowable Quantity) A threshold quantity of hazardous material (per control area)in a specific hazard class that once exceeded requires the application of additional administrative procedures, construction features, or engineering controls Less than or greater than MAQ, requirements are different nfpa.org16 Chapter 7 Gaseous Hydrogen 2016 edition Chapter is reorganized. General requirements Non-bulk systems greater than MAQ and less than 5000 ft3 Bulk systems greater than 5000 ft3 New section on Hydrogen Equipment Enclosures Changes to excess flow requirements becomes emergency isolation. nfpa.org17 Gaseous Hydrogen Separation Distances Separation distance table is in Chapter 7 Based on pressure, pipe diameter, exposure type No changes from 2011 edition, additional tables added from the 2013 edition of NFPA 55. Product of joint task group between NFPA 2 and 55 committees. The basis for separation distances is being reviewed by a Joint 2/55 task group for 2019 edition. nfpa.org18 Liquid Hydrogen System Separation Distances Table in 2011 edition - Minimum Distance from Liquefied Hydrogen Systems to Exposures. Extracted from NFPA 55, basis for separation distances is being reviewed by Joint 2/55 task group nfpa.org19 Gaseous Hydrogen Fueling Major rewrite to focus solely on requirements for dispensing of hydrogen to vehicles Overpressure protection allowed to meet Dispenser PRV requirements Change in Management of Change Documentation Revisions to Integrity Tests supporting SAE J-2601 Electrical Classification of Dispenser nfpa.org20 Parking and Repair Garages Chapters are no longer reserved in the 2016 edition Parking of hydrogen powered vehicles subject to the same requirements as traditional fueled vehicles Repair garages Major and Minor repair garages Requirements depend on type of work done. H2 detection and special ventilation needed only for major repairs involving work on fuel vehicle and and on-board fuel system nfpa.org21 Questions on NFPA 2 NFPA provides advisory services for NFPA members and AHJs On-line (NFPA.org) Toll-free number Questions directed to staff liaison nfpa.org22
