Smoke control systems are required in basements in Hong Kong under certain conditions. The differences in the smoke extraction rate listed in the two versions of fire service installation codes are discussed. Empirical equations on the smoke production rate appeared in the literature are used to explain the physics behind the codes. A design graph on the number of air changes per hour and the resulted clear height is recommended for local use.
