Fire barriers are structures designed to prevent the spread of fire and smoke within a building. They are typically made from fire-resistant materials and are strategically placed to protect critical areas, such as stairwells and exits. Fire barriers help to contain a fire, allowing occupants more time to evacuate safely and reducing damage to the property. These barriers can include walls, floors, and ceilings that meet specific fire-resistance ratings. Building codes often require fire barriers in commercial and residential buildings to enhance safety. Regular inspections and maintenance are essential to ensure that these barriers remain effective in case of a fire emergency.
