Brad Keyes discusses regulations related to new construction hazardous rooms

Q: One of the units in my hospital is about to go under expansion construction and they are looking to move combustible supplies from a storage room to a room that used to be a break-room in another area on the same floor. The break-room is greater than 50-square feet and the movement of supplies would then consider it a hazardous room. Since the room/facility was built in 2006 and is now considered existing with the adoption of the 2012 LSC, can these supplies be stored in the old break-room if the room is not 1 hour rated? The break-room has sprinklers, a self-closing and positive latching door, and the walls extend from the floor to the ceiling with the ceiling also resisting the passage of smoke.

A: You need to review Chapter 43 of the 2012 LSC. This is a change is use of a room but not a change in occupancy. Section 43.7.1.2 (2) says for existing healthcare occupancies protected throughout by an automatic sprinkler system, where a change in use or a room or space not exceeding 250-square feet results in a room or space that is described in 19.3.2.1.5(7), the requirements for new construction shall not apply provided the enclosure meets the requirements of 19.3.2.1.2 through 19.3.2.1.4.

 What this means is:

•  If your entire building is fully sprinklered;

•  If the break room is not more than 250-square feet

•  If you are moving combustible supplies into that room;

• If the break room meets the requirements for existing hazardous areas (walls, doors, and ceiling that resist the passage of smoke, self-closing positive latching door)

Then yes, your break room does not have to meet new construction requirements and be 1-hour fire rated. It would be permitted to have non-rated walls and doors as long as they are smoke resistant, and the door is self-closing.
