Help make industrial occupancies safer with the most current requirements for fire and explosion protection by deflagration venting.
NFPA® 68, Standard on Explosion Protection by Deflagration Venting, 2023 edition, reflects updated technology, evolving fire safety practices, and the knowledge and experience of experts in the field. The revised standard offers the latest information on the design, location, installation, maintenance, and use of devices and systems that vent the combustion gases and pressures resulting from a deflagration within an enclosure to minimize structural and mechanical damage.
Notable changes include:
Requirements combined for fireball and hazard distance requirements for gases and dust and moved into Chapter 6 for consistency in application
Revised partial volume calculations for both gases and dust to account for solid objects reducing the open-air volume available for mixing and for possible dust concentrations below the worst-case concentrations
Updated fundamental burning velocity values in the annex based on currently available data
Added an annex on vent sizing for hydrogen mixture
