Compliant Flammable Liquid Storage
In this article US Chemical Storage analyzes flammable liquids and proper storage techniques for keeping your personnel and investments safe and compliant.
Flammable and combustible liquids are present in almost every workplace. Manufacturing facilities and industrial operations regularly handle and store large quantities of flammable liquids inside their facilities. These dangerous materials can present risks to human health and the surrounding environment if handled or stored improperly. Find out how to safely store flammable liquid storage indoors with US Chemical Storage.
A flammable liquid according to OSHA, is “any liquid having a flashpoint below 100ºF(37.8ºC) except any mixture having components with flashpoints of 100ºF(37.8ºC) or higher, the total of which make up 99 percent or more of the total volume of the mixture.”
Flammable Liquid Hazard Classifications:
- Class • Flashpoint • Boiling Point • Chemical Examples
- Class IA • <73ºF (23ºC) • <100ºF(37.8ºC) • Pentane, ethyl chloride, propylene oxide, methyl ethyl ether
- Class IB • <73ºF (23ºC) • ≥100ºF(37.8ºC) • Acetone, ethyl ketone, benzene, methyl alcohol, gasoline
- Class IC • ≥73ºF and <100ºF (23 & 37.8ºC) • All boiling points • Turpentine, xylene, isopropanol, styrene, methyl alcohol
Flammable Limits (LFL & UFL)
If flammable vapors combined with the proper proportion of air become exposed to a source of ignition, combustion or an explosion can occur. The term proper proportion is also known as the flammable range or explosive range.
The term flammable range defines all concentrations of flammable vapors or gases that are in the air, in which a fire or explosion is likely to occur or a flame will travel if the concentration is ignited.
There are minimum concentrations of vapor in the air where a fire will not occur if a source of ignition is present, as well as maximum concentrations of vapor in the air, in which a flame does not occur if a source of ignition is present. These two limits are coined, the lower and upper flammable limits (LFL and UFL).
LFL: The vapor concentration in the air for the lower flammable limit, is too “lean” to ignite or explode.
UFL: The concentration of vapor in the air, in the upper flammable limit, is too “rich” to ignite or explode.
