Flammable Material & Storage Safety
Take the time to know what flammable liquids you're working with and what the necessary precautions are. Remember flashpoints, auto ignition temperatures, and the basic principles of air and vapor mixtures. When flammable liquid is within the explosive range, you need to take extra precautions and follow the rules. Flammable liquids are used in hundreds of thousands of processes and they're used safely every day. However, the potential for mishaps is always there. Someone forgets to do this or that or some procedure is violated.
The answer to answer flammable liquid safety is to follow company safety procedures and work rules and, of course, the information provided for the manufacturer. Each employee holds the key to safety when working with flammable liquids. Knowledge is the first step, but putting that information to work for you makes the difference in safety.
