What is the design purpose of smoke towers in facilities?

1. To allow smoke to vent directly outside

2. To create an air passage for firefighters

3. To limit heat and smoke penetration in stairwells

4. To circulate air throughout the building

The correct answer is: To limit heat and smoke penetration in stairwells

The design purpose of smoke towers in facilities is primarily to limit heat and smoke penetration in stairwells. This function is crucial in ensuring the safety of both residents and staff during a fire emergency. Smoke towers effectively channel smoke and heat away from evacuation routes, allowing for safer passage for individuals exiting the building. By preventing smoke from infiltrating stairwells, which are often designated as primary escape routes, smoke towers enhance visibility and air quality, enabling smoother and safer evacuations. Additionally, they can help to preserve clear paths for first responders as they navigate the facility to control the fire and assist those in need. This function is a critical aspect of building design and emergency response protocol, as it directly contributes to the safety of everyone in the building during a fire incident.
