Definitions:

Flammable Liquid - a liquid with a flashpoint below 100⁰F

Class IA - flashpoint below 73⁰F and boiling point below 100⁰F

Class IB - flashpoint below 73⁰F and boiling point above 100⁰F

Class IC - flash at or above 73⁰F and below 100⁰F Combustible Liquids - a liquid having a flash point at or above 100⁰ F. Class II Combustibles - Flashpoint above 100⁰F and below 140⁰F Class III Combustibles - Flashpoint at or above 140⁰F

Subclass IIIA - flashpoint at or above 140⁰F and below 200⁰F

Subclass IIIB - flashpoint at or above 200⁰F Substitution: Relatively safe materials sometimes may substitute flammable liquids in order to reduce the risk of fires. Any substituted material should be stable and nontoxic and should either be nonflammable or have a high flashpoint.

Storage & Usage of Flammable Liquids:

Flammable and combustible liquids require careful handling at all times. The proper storage of flammable liquids within a work area is very important in order to protect personnel from fire and other safety and health hazards.

• Storage of Flammable liquids shall be in NFPA approved flammable storage lockers or in low value structures at least 50 feet from any other structure. Do not store other combustible materials near flammable storage areas or lockers
• Bulk drums of flammable liquids must be grounded and bonded to containers during dispensing
• Portable containers of gasoline or diesel are not to exceed 5 gallons
• When not in use flammable liquids shall be kept in covered containers.
