Which statement about the safety of butyrate dope is correct?

• A. It is much less flammable.
• B. It dries faster.
• C. It adheres better to fabric.
• D. It costs less.

Answer: (A)

Flammability is the safety factor in play here. Butyrate dope is formulated from cellulose acetate butyrate and uses solvents that result in a much lower fire hazard compared with older nitrocellulose dopes. This reduces the risk of ignition during application, curing, and handling, which is a major safety advantage in the workshop. While drying rate, adhesion to fabric, and cost can vary with formulation, they are not safety advantages in the same direct way, so the statement about being much less flammable best reflects the safety characteristic being tested.
