Closers on Doors to CT Scan

Q: Do entrance doors to x-ray rooms and CT scanner rooms have to be controlled by door closers?

A: According to the Life Safety Code, they only need closers if they are considered to be hazardous rooms (normally not) or if the door in question is also part of the smoke compartment barrier wall. However, other codes and standards may apply. Be sure to check with your state and local authorities.
