  15. UL 1626: Water Distribution

  16. “This presentation most certainly does not represent the views of my company nor the views of the fire sprinkler industry.”

  17. “To date, there has never been a multiple loss of life due to fire in a structure with a properly designed, fully installed and well maintained sprinkler system”
