In a nine-story residential building (with commercial spaces on the lower floors), which of the following fire protection design practices are not in compliance with the regulations or exceed the required standards? The correct answers are ABD. (A) A mechanical pressurized ventilation system should be installed in a smoke-proof stairwell located adjacent to the 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 cybercafe located on the second floor without conditions for natural smoke exhaust (with an area of 15 m2) should be equipped with mechanical smoke exhaust
