Fire doors are specially designed doors that help prevent the spread of fire and smoke between different areas of a building. They are made from materials that can withstand high temperatures, such as steel or fire-resistant wood, and are often equipped with seals that expand when exposed to heat. This helps to create a barrier, giving people more time to escape and reducing damage to property. These doors are an essential part of a building's fire safety plan and are commonly found in commercial buildings, schools, and hospitals. Proper installation and maintenance of fire doors are crucial to ensure they function effectively during a fire emergency. Regular inspections help to identify any issues that could compromise their performance.
