Hospital Door Types Explained: OT, ICU, Radiology & More
Hospitals are one of the most demanding environments for door systems. Different rooms have very different requirements — from sterile OTs and pressure-controlled ICUs to lead-shielded radiology rooms — and using the wrong door type can compromise patient safety.
Operation theatre (OT) doors
OT doors are typically hermetically sealed sliding doors with stainless steel finish, hands-free operation and full perimeter sealing. Together they form part of the OT's contamination-control and pressure-cascade design.
ICU and ward doors
ICU and ward doors emphasize hygiene, durability and ease of cleaning. Wide-leaf hinged doors with vision panels and protective bumpers are common. Acoustic upgrades are often used in ICUs to reduce alarm noise.
Radiology and diagnostic doors
X-ray, CT scan, cath lab and nuclear medicine rooms require lead-lined doors with project-specific lead thickness and matching lead-lined frames. Lead glass vision panels are used where visibility is needed.
Corridor, stair and service doors
Hospital corridors, staircases and service rooms use fire-rated steel doors as part of the building's fire-compartmentation strategy.
Frequently Asked Questions
Which door is used in an operation theatre?
Hermetically sealed sliding doors with stainless steel finish and hands-free operation are the standard for modern operation theatres.
Why do radiology rooms need lead-lined doors?
Lead lining attenuates ionizing radiation. The thickness is chosen by the radiation physicist based on equipment kV and workload to keep dose rates below regulatory limits.
Do hospital doors need to be fire-rated?
Doors on evacuation staircases, lift lobbies, electrical rooms and many corridors must be fire-rated under the National Building Code and state fire-NOC requirements.
