The 2016 editions of NFPA 2, Hydrogen Technologies Code and NFPA 55, Compressed Gases and Cyrogenic Fluids Code, will be issued this month. NFPA 2 relies heavily on NFPA 55 for material on the safe storage and use of bulk and non-bulk quantities of hydrogen. This cycle is the first time that the two committees worked closely together to develop content, holding a joint second draft meeting last summer to review public comments on the material that is common to both documents. Major changes were made to NFPA 2 on fueling and repair garages for hydrogen fuel cell vehicles. NFPA 2 also added new material on hydrogen equipment enclosures, which are finding new uses throughout industry. NFPA 55 has revised the chapter on Carbon Dioxide, with a focus on beverage dispensing systems, and added new material on Liquid Nitrous Oxide systems. The committees have developed a new partnership, and are looking forward to working together during the next revision cycle.
