-STANDARD OPERATING PROCEDURE TEMPLATE
 This SOP is for work in which flammable/combustible liquids are NOT used in operations that often generate static electricity which can act as an ignition source; including the pumping or pouring of solvents between metal containers.  Those operations require grounding and/or bonding of the containers to prevent static buildup and a different SOP template in the UCSB SOP Library should be used:   ADVANCED FLAMMABLE AND COMBUSTIBLE LIQUIDS HANDLING
 (See also these related UCSB SOPs:  “Solvent Use:  Extractions, Distillations & Still Quenching” and  “Peroxide-Forming Chemicals”)

+**HAZARD OVERVIEW**
 Flammable and combustible organic solvents are amongst the most dangerous chemicals in the lab.   A measure of how ignitable a particular solvent is the flashpoint ; defined as the lowest temperature at which a material can form an ignitable mixture with air and produce a flame when a source of ignition is present.   The lower the flashpoint, the more easily the liquid can be ignited.   Most common organic solvents in the lab are readily ignited, with the exception of chlorinated solvents like dichloromethane which require more extreme conditions to burn.
 Flammable liquids (flash point < 100oF) are divided into three classes:
-Class 	Flash Point 	Boiling Point 	Examples

-IA	Below 73°F	Below 100 °F	Ethyl Ether
