Understanding NFPA and FPRF
NFPA – National Fire Protection Association• Non Profit Membership Association• Established in 1896; Approximately 65K members• Headquartered in Quincy, MA, though no geographic boundaries• Mission: Make the world safer from fire and related hazards• 300 plus “model Codes & Standards; administered by 8K volunteers
FPRF– Fire Protection Research Foundation• NFPA’s Research Affiliate: Separate non-profit research
organization• Mission: Facilitate research on behalf of the NFPA mission• Analogy: Similar to “Special Ops”, to address real-world problems

• NFPA 855: Standard for Installation of Stationary Energy Storage Systems (2020 edition)
• Standard development began in 2016.
• Final document released September 2019.
• Purpose: To establish fire protection criteria for ESS installations. — To consider and mitigate fire and life safety risks of
ESS installations
