D divide the firewall with a fire resistance limit of 4.00h into two fire zones on average, and set up an automatic fire extinguishing system.

6. When inspecting an office building, we learned from the drawings that the building is a reinforced concrete frame structure, and the design fire resistance limits of columns, beams and floors are 3.00h, 2.00h and 1.50h respectively, and each floor is divided into two fire protection zones. The following test results, does not meet the current national fire technical standards is ().

A. Change the normally closed Class A fire door originally designed in the inner corridor into a normally open Class A fire door.

B Move the original designed second-floor firewall to the corresponding position of the middle secondary beam of the first-floor restaurant, and the fire partition area still meets the specification requirements.

8. In the following description about the installation requirements of fire hydrant pipes, the correct one is ().

A. The pipeline passes through beams, basement shear walls, pools, etc. Should pass through the embedded metal pipe.

B the pipeline installation sequence is generally riser, horizontal pipe, branch pipe, main pipe and main pipe.

C. Pipe network flushing shall be carried out in sections after passing the pressure test.

D the test point of hydraulic strength test should be located at the highest point of the system pipe network.

E. The installation method of fire riser in tube well is from bottom to top.

9. Because of the large space and many partitions, large shopping malls bring a lot of inconvenience to fire control, especially in the layout of fire emergency lighting and evacuation signs.
