Regarding the design of protective ventilation for air-raid shelters, which of the following is correct? (A) Reliable airtight protection measures should be taken for ducts used for ventilation through walls. (B) In air-raid shelters that serve as storage areas during wartime, pressure measurement devices should be installed in the control rooms. (C) The rated air flow capacity of blast-proof valves should not be less than that of isolated ventilation systems during wartime. (D) The rated air flow capacity of filtering and absorption units must be greater than the air intake volume during gas filtration ventilation. The correct answer is D
I believe the correct answer to this question is D.
