Interior finish can contribute to flame spread in what way?

• A. It reduces smoke production
• B. It is flameproof and neutral
• C. It may produce smoke and toxic gases contributing to life hazard and property damage
• D. It has no effect on flame spread

Answer: (C)

Interior finish materials can influence how a fire grows and the danger to occupants. When these finishes burn, they often act as fuel and release heat, smoke, and toxic gases. The smoke and toxic products create life hazards for people and responders, reduce visibility, and can cause greater property damage. Because of this, interior finishes may contribute to flame spread by generating smoke and toxic gases. It’s not accurate to say they inherently reduce smoke, are completely flameproof, or have no effect—finishes can and do affect flame spread, especially if they are not properly rated for fire performance.
