Which statement best describes the primary objective of smoke control?

• A. To eliminate all smoke.
• B. To maximize ventilation for comfort.
• C. To limit smoke movement to keep egress paths clear and maintain tenable conditions.
• D. To increase visibility in stairwells.

Answer: (C)

Smoke control is about keeping people safe by managing how smoke and heat move through a building. The aim is to limit the spread of smoke so escape routes like stairs and corridors stay usable and the environment remains tenable long enough for occupants to evacuate and for responders to operate. It isn’t about eliminating all smoke—unrealistic in a real fire—nor about ventilating for comfort or trying to make stairwells more visible at the expense of life safety. By restricting smoke movement and protecting egress paths, tenable conditions are preserved where people need to get out and where firefighters may need access.
