NFPA 1: 2018 sneak peak, revised chapter on energy storage systems. #FireCodefridays

Blog Post created by Kristin Bigda Employee on Mar 10, 2017

Back in January the NFPA 1 Second Draft Report was posted online for public review.  This report summarizes the actions of the committee from their Second Draft meeting as well as provides a complete updated draft of the Code showing all of the revisions and responses to public comments.  Internally, we are now processing any NITMAMs (notice of intent to make a motion) that were received for NFPA 1 and a report on those motions that qualify for presentation at the Association Technical Meeting in June will be posted mid-April.

 

But, why wait any longer to check out some of the new requirements coming to the 2018 edition... 

 

Chapter 52, formally titled Stationary Storage Battery Systems, is being renamed to Energy Storage Systems and is undergoing a complete reorganization and rewrite for the 2018 edition.  The purpose of this rewrite is to recognize both established battery technologies and new technologies. This rewrite reflects existing and new applications of these energy storage systems.

 

 

Newly updated Chapter 52 will be organized into two main sections. Section 52.2 will address stationary storage battery systems having an electrolyte capacity of more than 100 gal (378.5 L) in sprinklered buildings or 50 gal (189.3 L) in unsprinklered buildings for flooded lead-acid, nickel-cadmium, and valve-regulated lead–acid (VRLA) batteries or used for facility standby power, emergency power, or uninterrupted power supplies. Section 52.3 is brand new for the 2018 edition and will address additional battery technologies. Specifically, it will cover energy storage systems having a capacity greater than that indicated in the table below:

 

More specifically, Section 52.2 will cover the following issues related to lead acid and nickel-cadmium batteries:
  • safety venting
  • thermal runaway
  • location and occupancy separation
  • spill control
  • neutralization
  • ventilation
  • signage
  • seismic protection
  • detection

 

Section 52.3 will address the following topics for other battery technologies:

  • stationary storage battery systems and capacitor energy storage systems
  • location and occupancy separation
  • outdoor installations
  • means of egress
  • maximum allowable quantities
  • battery arrays
  • hazard mitigation
  • listings
  • suppression and detection
  • ventilation
  • spill control
  • impact protection

The revision to Chapter 52 represents a piece of the effort that NFPA is putting forth to develop resources for its stakeholders related to energy storage systems and newer battery technologies.  The January/February 2016 edition of NFPA Journal contains a headline story highlighting the emerging safety questions facing enforcers and first responders as energy storage systems begin to revolutionize power management.  In addition, as these systems are rapidly becoming a reality across the United States and to help the fire service handle the unique challenges presented by these new technologies, NFPA has developed the Energy Storage System Safety Training CourseNFPA 855, Standard for the Installation of Stationary Energy Storage Systems is a new standard being developed to formally address these technologies.  NFPA 1 will evaluate NFPA 855 at their next meeting to check for consistency and/or extract provisions from the standard.

 

Look for future #FireCodefriday posts about additional new requirements coming to NFPA 1, 2018!

 

Happy Friday, stay safe!
