Question

the ____ of smoke control uses mechanical fans and ventilation to create a pressure difference across a barrier such as a wall.

exhaust method
peer pressure method
pressurization method
opposed air flow method

question 36
negative-pressure systems do not remove smoke from the building.

true
false

Explanation:

Analyze the first question

Using the Smoke Management Systems knowledge point, we examine the definition of smoke control methods. The question asks for the method that uses mechanical fans to create a pressure difference across a barrier (such as a wall) to manage smoke movement.

By definition, the pressurization method uses mechanical fans to establish a pressure difference across physical barriers, preventing smoke from leaking into protected areas (like stairwells or adjacent zones). Therefore, "pressurization method" is the correct choice.

Analyze the second question

The second question asks whether "Negative-pressure systems do not remove smoke from the building" is True or False.

Negative-pressure systems work by exhausting air and smoke out of a space, creating a lower pressure inside relative to the outside or adjacent spaces. This mechanical exhaust directly pulls and removes smoke from the building. Therefore, the statement that they do not remove smoke is False.

Answer:

Question 1

• exhaust method
• peer pressure method
• pressurization method (Correct answer)
• opposed air flow method

Question 2

• True
• False (Correct answer)
