What is a fire door?

A fire door is a specially designed door that is constructed to help contain and prevent the spread of fire within a building. These doors are made with materials that are fire-resistant, such as steel, gypsum, or solid wood, and are equipped with seals around the edges to prevent the passage of smoke and flames.

Fire doors are typically installed in buildings to protect escape routes and compartmentalize the building to minimize the spread of fire and smoke. They are designed to withstand high temperatures for a specified period of time, typically ranging from 20 minutes to 3 hours depending on the door's fire rating.

In addition to their fire-resistant properties, fire doors are also required to be self-closing and equipped with a fire-rated door closer to ensure that they automatically shut in the event of a fire. They are often marked with a fire-rated label or certification to indicate their compliance with fire safety standards.

Regular maintenance and inspections of fire doors are essential to ensure their effectiveness in the event of a fire. This includes checking for damaged or missing seals, proper functioning of the door closer, and ensuring that the door closes securely. Failure to maintain fire doors properly can compromise their ability to contain a fire and protect building occupants.
