NFPA 1: Insulated Liquid Carbon Dioxide Systems, #firecodefridays

Blog Post created by kristinbigda Employee on Mar 25, 2016

One of the many new topics being discussed during this revision cycle of NFPA 1 is insulated liquid carbon dioxide systems.  The use of CO2 and other simple asphyxiants has become prevalent in restaurants, mercantile, and other non-industrial facilities that utilize these gases for beverage dispensing and other applications. There have been fatalities in some of these facilities due to asphyxiation.

 

Included in the First Draft Report is a Committee Input proposing a new Section 63.9 to address the storage, use and handling of liquid carbon dioxide systems.  Committee Inputs are developed by the Technical Committee as "trial balloons" whereas the topic can be floated out to the public for additional review.  Committee Inputs are not considered an official revision to the document and are not part of the new document unless incorporated as a Second Revision during the Second Draft meeting.

 

The new language addresses permitting issues, pressure relief devices, physical protection, vent pipe systems, pressure and level indicators, piping systems, safety measures, signage, performance based design options, seismic and structural design, and outdoor systems.  The draft language incorporates some extracted text from NFPA 55, Compressed Gases and Cryogenic Fluids Code, as well as some NFPA 1 specific language.

 

Committee inputs seek the review of the public and submission of comments.  If you are interested in this Committee Input, or other work of the NFPA 1 Technical Committee, you can access the First Draft Report on the NFPA 1 web page under the 'next edition' tab.
