NFPA 99B: Standard for Hypobaric Facilities 2021 edition

Minimize the risk of fire and other dangers relating to the use of hypobaric systems with the new edition of NFPA 99B.

Initially created in response to the rise in use of hypobaric therapy in health care facilities and hypobaric chambers for space and air flight, NFPA 99B, Standard for Hypobaric Facilities, addresses the specific hazards inherent to these oxygen-enriched atmospheres.

The standard offers provisions for facility design, construction, operation, and maintenance to safeguard against fire, explosive, implosive, and electrical dangers. Additional Annexes provide everything from information on the nature of hazards and emergency response procedures to a helpful pressure table you can utilize in your work.

The 2021 edition is a must-have for manufacturers or anyone who owns, operates, or oversees facilities with hypobaric equipment.

NFPA 99B applies to all hypobaric facilities in which humans will be occupants or are intended to be occupants of the hypobaric chamber. This edition is revised to account for the latest industry knowledge and practices.

Changes to the standard include: 

  • Edited language on chamber construction to coordinate with NFPA 99, Health Care Facilities Code
  • A new requirement that electrical equipment installed in hypobaric chambers must now be listed to comply with the materials for plenums 
  • Updated references to the current editions of codes, standards, and other publications
