Access a one-stop source for the safe storage of hydrogen in the new edition of NFPA 2: Hydrogen Technologies Code.

The 2016 edition of NFPA 2: Hydrogen Technologies Code consolidates the latest fire and life safety requirements applicable to the generation, installation, storage, piping, use, and handling of hydrogen in compressed gas form or cryogenic liquid form.

This single comprehensive resource benefits enforcing officials when reviewing permits for occupancies storing, handling or using hydrogen or when inspecting existing facilities. It's also essential for designers, engineers, installers, contractors, facility managers, and anyone responsible for safety around applications involving:

  • Storage of hydrogen in bulk and non-bulk quantities
  • Use of hydrogen in laboratories
  • Dispensing and fueling of hydrogen for vehicles, along with vehicle repair
  • Systems for fuel cell power and generation, such as backup power systems using polymer electrolyte membrane (PEM) fuel cells and forklifts
  • Applications involving combustion processes and special atmospheres, including electrolytic production of hydrogen

Major changes in the 2016 edition include:

  • New section on hydrogen equipment enclosures to enable the safe use of these systems
  • Updated fueling chapter with new requirements for hydrogen fuel cell vehicle repair garages
  • Updated material extracted from thema 2016 edition of NFPA 55: Compressed Gases and Cryogenic Fluids Code on hydrogen storage, which divides requirements clearly into those for different size systems

Annexes include a sample ordinance adopting NFPA 2, an example of Class C furnace operational and maintenance checklist, and supplementary information on explosion hazards and protection in laboratories. (Softbound, 207 pp., 2016)
