3. The following statement about the division of smoke prevention zones is wrong is _______.
A. The place or part where the smoke exhaust system is installed should be divided into smoke prevention zones Smoke is discharged in time
D. The area of the smoke-proof zone is too small, the smoke storage capacity is enhanced, and the smoke is easy to spread to the adjacent smoke-proof zone.
E. The division of the smoke-proof zone should comprehensively consider the building type, building area and height, ceiling height, storage Factors such as the shape of the smoke warehouse
Answer BD Analysis: The division of smoke-proof partitions The place or part of the smoke exhaust system should be divided into smoke-proof zones and should not span fire-proof zones.When the area of the smoke-proof partition is too large, the horizontal jet protection of the flue gas will entrain a large amount of cold air and settle, which is not conducive to the timely discharge of the smoke. The division of smoke prevention zones takes into account factors such as building type, building area and height, ceiling height, and shape of smoke storage bins. Therefore, the answer to this question is BD
4. The following is an industrial building.

7. The fire of the following substances does not belong to the category D fire _______.
A.Aluminum-magnesium alloy For example, potassium, sodium, magnesium, titanium, zirconium, lithium, aluminum-magnesium alloys and other metal fires. Therefore, the answer to this question is BCDE
8. The following statement about the setting of the movie theater conforms to the specification and is ______.
A. When installed in other civil buildings, at least two independent safety exits and evacuation stairs should be set up. When arranged on the fourth floor and above, the evacuation doors of a hall or room should not be less than 2 and the construction area of each auditorium should not be larger than 400㎡. There should be no less than 2 evacuation doors for halls and rooms, and the building area of each auditorium should not be larger than 400 square meters. Construction should not exceed 2 floors. If it is really necessary to set up in other civil buildings, at least one independent safety exit and evacuation stairs should be set up and should meet the following requirements: 1. Fire partition walls and Class A fire doors with a fire resistance rating of not less than 2.00h should be used to separate them from other areas ;2. When it is installed in a building with first or second fire resistance class, the audience hall should be arranged on the first, second or third floor. If it is really necessary to be arranged on the fourth floor or above, the evacuation door of a hall or room should not be less. The building area of each auditorium should not be larger than 400 square meters; 3. It should not be arranged on the third floor or above in the building with the third-grade fire resistance; 4. If it is arranged underground or semi-underground, it should be arranged at The first basement should not be set on the third and lower floors. Therefore, the answer to this question is BCD
