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 4

Who is the NFPA? NEC is directly adopted in: • • • 13 different countries Mexico Central and South America nfpa. org 5

Who is the NFPA? Over 200 translations of NFPA's codes and standards. – – – Spanish French Portuguese Mandarin Korean Japanese nfpa. org 6

South Africa Connection • In 2013 the NFPA signed a MOU with Forest Fire Association, address wildfire safety concerns in the wildland/urban interface (WUI). 7

NFPA involvement with Electric Vehicles • Electric Vehicle Safety for Emergency First Responders • Batteries reigniting 8
