The smoldering combustion hazards of cellulosic loose fill insulation materials fall into three categories: smolder initiation, smolder propagation and transition from smoldering into flaming. Our previous findings on the initiation problem are summerized
The burning of more than a single fuel item in a room fire has not been well characterized. The first step in describing multiple item burning is to determine if, in fact, will occur. This question has been experimentally explored from two aspects. (1) The
Ten mattress types were subjected to full-scale fire tests in the earlier part of this project. Burning behavior was determined and hazard was assessed by classifying into performance groups. In the present study bench-scale test procedures were examined
Pressurized stairwells and pressurized elevators can be used as a means of providing a smoke free exit route during fire situations. This paper describes a computer program which analyzes systems intended to pressurize stairwells or elevator shafts. The
A series of seven large-scale room burnout fire tests was conducted with a set of selected residential floor-ceiling assemblies to provide data on the performance of the assemblies; these will be compared with the results in future tests on the same
