What safety feature is crucial for the ventilation system regarding pressure?

It should maintain pressure levels equal to indoor pressure
It must ensure no pressure fluctuation
It must maintain pressure greater than outdoor atmospheric pressure
It should maintain pressure no less than outdoor atmospheric pressure

The correct answer is: It should maintain pressure no less than outdoor atmospheric pressure

The key safety feature for the ventilation system in relation to pressure is that it should maintain pressure no less than outdoor atmospheric pressure. This is essential because maintaining this pressure balance helps prevent backdrafts, which can introduce harmful gases and contaminants into the building. If the pressure inside is less than the outdoor atmospheric pressure, it can create negative pressure conditions, risking the infiltration of combustion gases from heating appliances or exhaust systems. In addition, having indoor pressure at or above atmospheric levels ensures proper airflow and prevents issues related to insufficient ventilation, which could lead to the accumulation of dangerous carbon monoxide levels or other hazardous materials. This safety feature helps protect occupants’ health and safety by ensuring that the ventilation system operates effectively and minimizes the risk of dangerous air quality issues.
