Where are smoke curtains required?

#### Commercial Buildings

- **Atrium Areas**: Atriums typically connect multiple floors, and to prevent smoke from spreading to other areas, smoke curtains are necessary for fire separation.

- **Large Malls and Supermarkets**: These places have large areas and high population densities. Smoke curtains help divide smoke compartments and control smoke spread, ensuring safe evacuation of people.

- **Office Buildings**: In corridors, lobbies, and other public areas, installing smoke curtains can prevent smoke from spreading into stairwells, elevator shafts, and other critical areas.

#### Industrial Facilities

- **Factories and Warehouses**: Especially in Class C and above factories and warehouses where there is a risk of fire, smoke curtains are needed to divide smoke compartments and protect both personnel and property.

- **Industrial Parks**: In common areas or connecting passages between buildings, installing smoke curtains can prevent smoke from spreading between different structures.

#### Public Facilities

- **Subway Stations, Train Stations, Airports**:"title": "Public facilities with high foot traffic", "description": "These locations require smoke curtains to effectively isolate smoke during fires, ensuring safe evacuation."

- **Hospitals, Schools, Nursing Homes**: Places with vulnerable populations need special attention to safety. Smoke curtains can help ensure that smoke does not infiltrate critical areas such as patient rooms, classrooms, and living quarters.

In addition, local building codes and regulations may specify additional requirements for the installation of smoke curtains based on the specific use of the building, its size, and occupancy levels. Always consult with local authorities or a professional fire safety consultant to ensure compliance with all applicable regulations.
