Question

Horizontal ventilation can be employed effectively in a basement if the basement:

a) Has no windows
b) Is properly sealed
c) Is well-ventilated
d) Contains hazardous materials

Answer 1

Horizontal ventilation is effective in a basement that is well-ventilated to prevent hazardous gases like radon from accumulating. Special fan-and-vent systems help improve air exchange and reduce indoor pollution levels.

Step-by-step explanation:

Horizontal ventilation can be effectively employed in a basement to minimize the accumulation of radon gas, which comes from the ground and is denser than air. The correct answer to the question 'Horizontal ventilation can be employed effectively in a basement if the basement:' is c) Is well-ventilated. Basements require proper ventilation to prevent the buildup of hazardous gases like radon. Effective ventilation systems might include special fan-and-vent systems that draw air from below the basement floor, preventing it from entering the living space, and then vent it above the house's roof. These systems, along with natural and mechanical ventilation, help maintain a good air exchange rate, reducing the levels of indoor pollutants.
