2012 Wind farm fire on Hawaii nfpa.org

Agenda Involvement with electrical projects Applicable NFPA standards New standard on ESS

Who is the National Fire Protection Association (NFPA)? Nonprofit Organization Standards Development Organization (SDO) Research, Training, Education nfpa.org

Who is the NFPA? NEC is directly adopted in: 13 different countries Mexico Central and South America nfpa.org

Who is the NFPA? Over 200 translations of NFPA's codes and standards. Spanish French Portuguese Mandarin Korean Japanese nfpa.org

South Africa Connection In 2013 the NFPA signed a MOU with Forest Fire Association, address wildfire safety concerns in the wildland/urban interface (WUI).
