A hospital patient care suite: glass-fronted patient rooms along a short inner hallway, a staffed nurse workstation, and a pair of corridor doors at the far end

Code

Suites in health care, kept simple

Everyone seems to have their own definition of a suite. Here is what the code actually allows, and the numbers CMS still enforces.

Start the lesson

Close-up of a rated door edge and frame, scuffed and chipped from carts and traffic

LESSON / 003

Repair

Bent edge guards: a 10-minute fix

Edge guards on busy corridor pairs get twisted and stop the doors from closing. Often you can straighten them yourself instead of buying new ones.

Hardware

Fail safe vs fail secure

We see both on almost every campus, and it gets confusing. What each one does when the power goes out, and which one a fire door needs.

Start the lesson

A UL Listed Fire Door Frame label riveted to a painted steel frame, with no hourly rating

LESSON / 001

Labels

A frame label with no hours on it

The label says “Fire Door Frame” and nothing else. Is that frame good for your opening? Usually yes — with one thing to check.
