Facts on Flammable Liquids and proper flammable liquid storage.Fire is a visible heat energy being released from rapid oxidation of a fuel. Something is on fire, when the exothermic release of heat from oxidation reaction reaches the visible light level. A perfect fire triangle exists when three components exist which include Oxygen, Fuel and Heat.
Air provides oxygen for combustion, the amount of heat requires various ignition characteristics. Fuel is any substance that will prolong combustion after the initial heat source. The main application is on preventing a fire from starting and removing any one leg of the fire triangle.
The characteristics of a flammable liquid is one having a flash point below 100 farenheit and having a vapor pressure not exceeding 40 lbs per square inch absolute at 100 farenheit. A combustable liquid has a flash point at or above 100 farenheit. In any liquid there is a constant movement of molecules, as temps go up molecules become faster with some acquiring energy to escape from the liquid surface. When vapor escapes from a flammable liquid into the air an explosion may occur depending on the air/vapor mixture.
Proper containment of the flammable liquid to prevent it from spreading in the event of a fire is a main function of all flammable safety storage equipment. Equipment includes
Flammable Storage Cabinets ,
safety cans, bench cans, rinse and wash tanks and other waste containers.
Dissipation of heat to prevent flammable liquid vapor from reaching its igniting temperature is built in to certain types of safety containment products. The flame arrester is common in safety cans. Closing out oxygen is another factor of safety containers. When a safety containment product is air tight is shuts off the oxygen level thus the supply for that fire to live on.
Factors that are important to look at when planning your safety fire prevention list:
Make sure the products are FM approved, products meeting these requirements have been recognized by a nationally recognized independent testing laboratory established by the insurance industry.
Control Area: A building within flammable and combustable liquids are allowed to be stored, dispensed or handled in quantities that do not exceed the maximum allowable quantity.
NFPA Code 30: The code developed by NFPA to cover the safe storage and handling of flammable and combustible liquids.
