What is the maximum smoke-developed index for wall and ceiling finishes?

The correct answer is: 450

The maximum smoke-developed index for wall and ceiling finishes is set at 450. This standard is established to ensure that materials used in these areas minimize the amount of smoke produced when subjected to fire. Smoke production plays a critical role in life safety during a fire because dense smoke can obscure visibility and inhibit evacuation, leading to increased risk of injury or death. By limiting the smoke-developed index to 450, the code aims to reduce the potential for smoke-related hazards and provide occupants with a better chance to escape in case of a fire. Materials that meet this requirement are deemed to contribute to a safer environment in residential and other types of buildings. The other options represent indices that exceed the maximum allowed limit for these finishes, which would not comply with safety standards designed to mitigate smoke hazards in construction.
