Laboratory Safety-Flammable Liquids Flammable Liquids and Fire Codes for Laboratories

Laboratory Safety-Flammable Liquids Properties of Flammable Liquids Invisible Vapor is the Main Concern!

Laboratory Safety-Flammable Liquids Properties of Flammable Liquids Definitions: FLASH POINT The temperature at which a liquid gives off sufficient vapors to form an ignitable mixture with air…near the surface of the liquid.

Laboratory Safety-Flammable Liquids Properties of Flammable Liquids Definitions: Ignition Temperature The minimum temperature required to initiate or cause self-sustained combustion without ignition from an external source. Also called auto- ignition temp.

Laboratory Safety-Flammable Liquids Properties of Flammable Liquids Definitions: Upper and Lower Explosive Limits The range of concentration of a flammable gas or vapor (% volume in air) in which a explosion can occur upon ignition in a confined area.
