Which terms indicate that a material will burn easily?

• A. Flammable and inflammable
• B. Combustible and ignitable
• C. Nonflammable
• D. Fire-resistant

Answer: (A)

When a material will burn easily, the terms flammable and inflammable are used. They both indicate a low ignition point and that the substance can catch fire readily when exposed to heat, sparks, or flames. In safety contexts, infl ammable is treated the same as flammable, even though the word can be confusing in some usage. The other terms describe different fire-risk levels: combustible and ignitable cover materials that can burn but not as readily as flammable; nonflammable means it resists ignition; fire-resistant indicates it is designed to resist burning. So, flammable and inflammable point to easy burning, which is why they are the best choice.
