Definition

1. Noun:
   • A fire-resistant door designed to prevent the spread of fire and smoke: A "fire door" is a specially constructed door made of fire-resistant materials. Its primary function is to act as a barrier, compartmentalizing a building to stop or slow the progression of fire and smoke from one area to another, allowing time for evacuation and for firefighters to respond.

Usage

• Fire doors are a critical component of a building's passive fire protection system. They are typically required by building codes in specific locations like stairwells, corridors, and between different occupancy areas.
• They are often self-closing or must be kept closed, and are sometimes held open by electromagnetic devices that release automatically when a fire alarm is activated.

Examples

• Noun:
  • Please ensure the fire door at the end of the corridor is never propped open.
  • The building inspector checked the rating and seals on every fire door in the new hospital wing.

  • This isn't just a regular door; it's a fire door and must remain closed at all times.
• "Fire door assembly": Refers to the entire unit including the door, frame, hardware, and seals, which together are rated for fire resistance.
  • The fire door assembly must have a certification label showing its fire-resistance rating.
