Fire doors are essential components in building safety, designed to resist the spread of fire and smoke, providing critical protection in the event of a fire emergency. These doors are constructed with materials that can withstand high temperatures, and they are equipped with intumescent seals that expand under heat, creating a barrier to prevent the passage of flames and smoke. Fire doors play a crucial role in compartmentalizing buildings, allowing occupants to evacuate safely and providing time for emergency responders to control the situation. They are strategically placed in fire-resistant walls and are often part of a comprehensive fire protection system. Regular maintenance and adherence to fire safety standards are imperative to ensure the effectiveness of fire doors in safeguarding lives and property.
