Industrial Hazards

5 Posts authored by: sbershad Employee

Looking forward to Session T16 this morning, Inspecting Facilities for Combustible Dust Hazards, in S404d.  It will be a good follow-up to the presentation yesterday on NFPA's Combustible Dust Standards.  With the development of NFPA 652, Fundamentals of Combustible Dust, we are taking important steps to prevent combustible dust incidents.

 

See you there!

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.

The Hydrogen and Industrial Medical Gases (NFPA 2 and NFPA 55) technical committees have formed a joint task group to look at separation distances for liquid and gaseous hydrogen.  Hydrogen fueling stations for fuel cell vehicles are currently being built in California and are planned for the Northeast and the rest of the country.  Separation distances in the codes have presented a challenge for the installation of new stations.  The group is working on developing the basis for and modeling release scenarios that can be used to establish safe separation distances.  The goal of this work is to develop public input for the 2019 edition of both documents.

The next edition of NFPA 484, Standard for Combustible Metals, is open for public input until July 6th, 2015. To submit a public input using the online submission system, select NFPA 484 from the Document information pages (list of NFPA codes & standards) . Once on the NFPA 484 document information page, select the link "The next edition of this standard is now open for Public Input" to begin the process.  You will be asked to sign-in or create a free online account with NFPA before using this system.

 

The First Draft meeting for the document is scheduled for August 25th to 27th at Oak Ridge National Laboratory in Knoxville, TN.  One goal of the committee at the first draft meeting is to work towards correlating 484 with the new NFPA 652 standard, Fundamentals of Combustible Dusts.  Additional details on the meeting can be found on the document information page for NFPA 484.

NFPA 52 Reorganization

Posted by sbershad Employee Jun 17, 2015

The Vehicular Alternative Fuel Systems technical committee has been working on a complete reorganization of NFPA 52, the Vehicular Gaseous Fuel Systems Code.  This code covers both compressed and liquid natural gas fueled vehicles.  These vehicles have seen increased use over the past several years, particularly in fleet usage.  Natural gas is a clean burning fuel, creating less carbon dioxide emissions than gasoline or diesel.  The new edition, just finishing up second draft now, will be simpler and easier for the user, grouping material common to both fuels together, and then listing supplemental requirements for each fuel.  The new edition will be published in 2016.
