The two primary hazards associated with flammable and combustible liquids are explosion and fire. |
Safe handling and storage of flammable liquids requires the use of approved equipment and practices per OSHA standards. |
The determining factor in whether a liquid is flammable or combustible is its flashpoint. Flashpoint: The minimum temperature at which a liquid gives off enough vapor within a test vessel in sufficient concentration to form an ignitable mixture with air near the surface of the liquid. Remember, it is the vapors, not the liquid, that Burns! A chemical’s flashpoint is listed on the MSDS under the Fire and Explosion section. | Fish Printing Purse Deluxe Portable Receiving Koi Small Cute Bag 6q5fW

Flammable Liquid Classifications Any liquid having a flashpoint below 100 deg. F (37.8 deg. C) or higher, the total of which make up 99 percent or more of the total volume of the mixture. Flammable liquids shall be known as Class I liquids. Class I liquids are divided into three classes as follows:
|
Combustible Liquid Classifications Any liquid having a flashpoint at or above 100 deg. F (37.8 deg. C). Combustible liquids shall be divided into two classes as follows:
Class III liquids are subdivided into two subclasses:

Explosive limits involve the concentration level of the given chemical in the air. In popular jargon, a vapor/air mixture below the flammable limit is too lean to burn or explode. A mixture above the upper flammable limits is too rich to burn. Most flammable liquids are volatile, meaning they evaporate quickly, and can reach a concentration in the air that could lead to an explosion. |
