Which term means not susceptible to burning violently when ignited?

• A. Flash Resistant
• B. Fireproof
• C. Flammable
• D. Nonflammable

Answer: (A)

Materials are described by how easily they ignite and how they behave when exposed to flame. The term that fits “not susceptible to burning violently when ignited” is flash resistant. This describes a material that resists ignition and does not burn violently when briefly exposed to a flame, though it may still burn if the flame is kept on it or exposed longer.

Flammable would mean it catches fire readily, which is the opposite of what the statement describes. Nonflammable implies it does not burn at all under typical conditions, which is a stronger claim than “not susceptible to burning violently” and isn’t the usual way these terms are used. Fireproof suggests complete, guaranteed immunity to fire, which is not realistically achievable in ordinary materials.
