What is the primary function of a smoke barrier in a building?

The primary function of a smoke barrier in a building is to prevent the spread of smoke during a fire incident. Smoke can travel quickly and can cause harm or disorientation to occupants, making effective management of smoke crucial for safety. Smoke barriers are designed to contain smoke within certain areas of a building, thereby protecting escape routes, such as stairwells and exits, and improving overall fire safety measures. By limiting the movement of smoke, these barriers help ensure that occupants have a clearer path to safety and that emergency responders can operate more effectively. This function is particularly important in larger commercial buildings where smoke can spread rapidly, potentially leading to dangerous conditions.
