With all the basic background information collected, Section 307 of the IBC provides hazardous materials quantity limits for each physical and health hazard subcategory. separation between buildings refers to the horizontal distance between two buildings measured from the nearest point on either building wall to the nearest point on the other. Figure 2 shows an example of the SDS information available in Section 14 (4). This 1-hour rating would span all occupancy classifications and uses including office buildings. As code consultants, there are certain questions from clients that come up quite often. In general, a fire separation is defined as a containment structure that prevents the spread of fire. The occupancy classification process can provide a perspective on the inventory limits of raw materials in process materials and finished products allowed by the building and fire code. Architecture refers to a gap between two buildings that can be physical or visually significant. The CSB Factual Update mentions that the manufacturing tanks were not completely sealed. Learn about wood products and make a new contact to facilitate material fulfillment for your next project. This interpretation is confirmed by the commentary to section 707.3.10 which states: One of the alternatives available in addressing fire protection systems in many buildings is to divide the building into separate fire areas (see the definition of fire areas in Chapter 2). This maneuver allows for the withdrawal of friendly forces to be conducted in a safe and orderly manner and is often used to provide a tactical advantage when engaging a numerically superior enemy force. It appears that much of this uncertainty is related to changes in the code provisions over the years. In a typical scenario, the fire-rated separation walls dont do anything but provide fire and sound separation between the apartments or condo units in a building. In these situations, all classifications should be documented to compare against allowable quantities for the occupancy determination.
