Which statement best describes the safety advantage of butyrate dope over nitrate dope?

• A. It is cheaper.
• B. It is much less flammable.
• C. It cures faster.
• D. It has higher tensile strength.

Answer: (B)

The key safety benefit is the much lower flammability. Nitrate dope uses nitrocellulose, which is highly flammable and can ignite from heat, sparks, or friction, posing fire risks during application, storage, and service. Butyrate dope uses cellulose acetate butyrate, which has far fewer flammable vapors and a lower ignition risk, making handling and use safer. The other factors—cost, curing speed, and tensile strength—are not primary safety advantages, so they don’t describe the benefit as effectively.
