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.”

Code Development ProcessCodes and Standards development through consensus processTechnical Committees develop documents through public input and comment process
Balanced committee makeup – no more than one-third from each member category

5Slide6
Code Adoption Code must be adopted to be enforceableAuthority 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.

6Slide7
California Adoption 2013 California Fire Code references NFPA 55 for setback distances from storageCalifornia has adopted the 2011 edition of NFPA 2. State Fire Marshall action.
2016 edition was issued June 15
th
, 2015.
Adoption of the
2016 edition is in progress

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 enforcersStructured so that it works seamlessly with building and fire codes.
nfpa.org
8Slide9
Purpose of NFPA 2The 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.orgSlide10
Application This shall apply to the production, storage, transfer and use of hydrogen in all occupancies and on all premisesThe 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.orgSlide11
Exemption Onboard vehicle or mobile equipment components or systems including the onboard GH2
or LH
2
fuel supply
Mixtures of GH2 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.orgSlide12
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.orgSlide13
Retroactivity NFPA 2 does not apply retroactively unless
authority having jurisdiction determines that a distinct and identifiable hazard exists.

Chapter 6 – General Hydrogen RequirementsConcept 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
controlsLess than or greater than MAQ, requirements are different
nfpa.org
16Slide17
Chapter 7 – Gaseous Hydrogen2016 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.

Gaseous Hydrogen Separation Distances Separation distance table is in Chapter 7Based 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.

Parking and Repair Garages Chapters are no longer reserved in the 2016 editionParking 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
