For a nine-story residential building (with commercial units on the lower floors) undergoing fire protection design, which of the following practices are inconsistent with or exceed the regulatory requirements? The correct answers are ABD. (A) A mechanical pressurized ventilation system should be installed in a smoke-proof stairwell located against an exterior wall and with conditions for natural smoke exhaust. (B) The residual pressure in the vestibule equipped with mechanical pressurized ventilation should be 20 Pa. (C) Mechanical smoke exhaust should be installed in an atrium with a clear height of 15 meters. (D) A computer shop located on the second floor without conditions for natural smoke exhaust (with an area of 15 m2) should be equipped with mechanical smoke exhaust
Is BCD not compliant? ? ? ?

A) A mechanically pressurized ventilation system is installed in smoke-proof stairwells located against exterior walls and with conditions for natural smoke exhaust. Code for Building Design 9.1.1 (B): The residual pressure in the vestibule for mechanically pressurized ventilation shall be 20 Pa. Code for Building Design 9.3.3: A mechanical smoke exhaust system is required in internet cafes on the second floor of buildings that do not have natural smoke exhaust conditions (with an area of 15 m2), at a pressure of 20–30 Pa (D). Code for Building Design 9.1.3
