Which statement is true about flammable terminology?

• A. Inflammable means not flammable
• B. Flammable means capable of burning
• C. All volatile chemicals are non-flammable
• D. Combustible and flammable are the same

Answer: (B)

Understanding flammable terminology means focusing on how easily a substance can catch fire. A material described as flammable is capable of burning; it can ignite and sustain combustion under typical conditions. This directly aligns with safety definitions and explains why the statement is true. Inflammable is often misunderstood because it looks like it would mean “not flammable,” but historically it has the same meaning as flammable, not the opposite. Volatility refers to how readily a substance forms vapor, which can influence flammability, but volatility alone doesn’t determine whether something is flammable. Combustible materials generally require higher temperatures to ignite than flammable ones, so they are not the same.
