An NHS fire door is typically tested and rated to contain fire, smoke and toxic fumes for a minimum of 30 minutes , with some higher‑risk areas using doors rated for 60 minutes or more.

Core standard

  • Most NHS hospital fire doors are specified as FD30, meaning they are tested in a lab to resist fire, smoke and hot gases for at least 30 minutes under standard test conditions.
  • In higher‑risk parts of a hospital (for example plant rooms or routes critical for evacuation), FD60 doors may be used, which are tested to perform for at least 60 minutes.

What “tested time” really means

  • The rating (FD30, FD60, etc.) comes from controlled fire tests where the complete door set is exposed to very high temperatures and observers measure how long it prevents flames and hot gases from passing through.
  • The test time is a minimum benchmark; in real use, poor installation, damaged frames, missing seals or wedges holding the door open can drastically reduce the actual protection time.

Quick Scoop: what to remember

  • If you see a question such as “How long is an NHS fire door tested to contain fire, smoke and toxic fumes?”, the expected minimum answer is 30 minutes (FD30).
  • However, hospitals also use 60‑minute (FD60) doors in certain locations, so the practical range in NHS settings is usually 30–60 minutes depending on the risk assessment.
