A smoke barrier is a type of construction feature designed to prevent the spread of smoke within a building during a fire. It is typically made of fire-resistant materials and is strategically placed to create a barrier that limits smoke movement between different areas. This helps protect occupants and allows for safer evacuation. Smoke barriers are often used in conjunction with other fire safety systems, such as fire doors and sprinkler systems. They are an essential part of building codes and regulations, ensuring that structures provide adequate protection against smoke inhalation, which can be a significant hazard during a fire.
