A fire curtain is a safety device designed to prevent the spread of fire and smoke within a building or other enclosed space. It is typically made of fire-resistant materials and is installed in areas where fire hazards are present, such as in theaters, auditoriums, and commercial or industrial buildings.
The main purpose of a fire curtain is to create a barrier that can contain a fire to a specific area, protecting the occupants of the building and allowing for a safe evacuation. It is usually installed above an opening, such as a stage or an entrance, and is operated by a fire alarm or manual control.
When activated, the fire curtain will descend rapidly, dividing the space into separate compartments, limiting the airflow and preventing the spread of fire from one area to another. The curtain is typically sealed at the sides and bottom to ensure a tight closure, and it may have fire-resistant glass panels to allow for visibility or to serve as emergency escape routes.
Fire curtains are essential safety features in buildings and are subject to stringent regulations and standards to ensure their reliability and effectiveness. Regular maintenance and testing are necessary to ensure that they are in proper working condition.
The etymology of the word "fire curtain" is quite straightforward. The word "fire" originates from the Old English word "fȳr" which means "fire, flame". It can be traced back to the Proto-Germanic word "fūr" and the Proto-Indo-European root "pūr" meaning "fire". The term "curtain" comes from the Middle English word "curteine", which entered the language from Old French "cortine" meaning "curtain, tapestry". The Latin word "cortina" is believed to be the root for this term. When combined, "fire curtain" refers to a fire-resistant curtain used as a safety measure in theaters, designed to descend in case of a fire outbreak to separate the stage from the audience and prevent the spread of flames.
