Hazardous Rooms

Q: When dividing hazardous areas (particularly storage rooms exceeding 100 square feet), if there are several rooms in one area, is the one-hour fire rating allowed to surround the perimeter of all the rooms or does each room require a separate fire-rating?

A: There is no Life Safety Code requirement that would prohibit you from ‘grouping’ your multiple hazardous rooms together, into one large hazardous room, even though the multiple rooms are separated by non-rated barriers. So, yes, you can have the 1-hour fire rated barrier go around the outer perimeter of all the rooms and everything inside the 1-hour fire rated barrier would be considered a hazardous area.
