ABSTRACT

Coffee Break Training: Inspection Techniques: Fire-Resistive Construction Repairs   [open pdf - 390KB]

"Many residential-type occupancies employ garbage, linen, or (as pictured) laundry chutes that enable housekeeping staff to easily send rubbish or laundry materials to a terminal room where they can be processed. The model building codes typically require that these conveyances be treated as vertical shafts, and have minimum fire-resistive construction requirements of 1 or 2 hours depending upon the height of the building in which they are located. In today's example, the fire-resistive integrity of this 1-hour-rated shaft has been compromised, evidently to provide access to the plumbing utilities. These openings create a serious vulnerability to the shaft's structural integrity, and perhaps the entire building, if a fire occurred in or entered the shaft and ignited the combustible framing."
