  1. Flammable Liquids and Fire Codes for Laboratories

  2. Properties of Flammable LiquidsInvisible Vapor is the Main Concern!

  3. Properties of Flammable LiquidsDefinitions: FLASH POINTThe temperature at which a liquid gives off sufficient vapors to form an ignitable mixture with air…near the surface of the liquid.

  4. Properties of Flammable LiquidsDefinitions: Ignition TemperatureThe minimum temperature required to initiate or cause self-sustained combustion without ignition from an external source. Also called auto-ignition temp.

  5. Properties of Flammable LiquidsDefinitions: Upper and Lower Explosive LimitsThe range of concentration of a flammable gas or vapor (% volume in air) in which a explosion can occur upon ignition in a confined area.

  6. The Phenomenon of Fire Energy Source Fuel Chain Reaction Oxygen or Oxidizer

  7. Fire Codes • Who Regulates Flammables? • State Fire Marshal (NFPA, OBBC, and Ohio Fire Code) • OSHA (Occupational Safety) • DOT (Transportation) • EPA (Flammable Waste)

  8. Fire Codes-NFPA • Flammable liquids have a flash-point of less than 100°F • Combustible liquids have a flash-point of 100°F or greater

  9. Fire Codes-NFPA Flammable Liquid Classification Class IA- FP<73°F, BP<100°F Class IB- FP<73°F, BP>100°F Class IC- 73°F >FP<100°F Class II- 100°F >FP<140°F Class IIIA- 140°F >FP<200°F Class IIIB- FP > 200°F
