    LOWEST TEMPERATURE AT WHICH A SUBSTANCE GIVES OFF SUFFICIENT VAPOR TO FORM AN IGNITABLE MIXTURE.
  7. WHAT IS FIRE POINT?
    TEMPERATURE SLIGTLY ABOVE FLASH POINT THAT ALLOWS FOR SUSTAINED COMBUSTION.
  8. WHAT IS IGNITION POINT?
    MINIMUM TEMPERATURE AT WHICH SELF-SUSTAINING COMBUSTION OCCURS WITHOUT AN EXTERNAL IGNITION SOURCE.
  9. WHAT IS THE FIRE TRIANGLE?
    • FUEL
