Room type code 272 "Walk-In Environmental Chamber" is a specialized laboratory room type. These chambers may control temperature, humidity, lighting, or any combination of these conditions.
Any walk-in temperature-controlled room, a refrigerator or a freezer, used to support non-laboratory space should have the appropriate service room type which matches the room it supports. The most common room type for walk-in refrigerators and freezers will be 635, Food Facility Service. Other service room types are possible.
Reach-in refrigerators and freezers are equipment and not coded as rooms.
NOTE: To make it easy to find all of your coolers or freezers, add "Walk-In Cooler" or "Walk-In Freezer" to the Brief Room Info.
Table 1 contains a list of service room types which may apply to spaces containing refrigerators or a freezers used for non-laboratory purposes.
