Richard D. Peacock, Jason D. Averill, Erica D. Kuligowski, Richard W. Bukowski
Historically, building egress systems have evolved in response to specific large loss incidents. Currently, systems are designed around a concept of providing stair capacity for the largest occupant load floor in the building with little or no

Stairwell Evacuation from Buildings: What We Know We Don't Know

Richard D. Peacock, Jason D. Averill, Erica D. Kuligowski
Occupant descent down stairwells during building evacuations is typically described by measureable engineering variables such as stairwell geometry, speed, density, and pre-evacuation delay. In turn, predictive models of building evacuation use these

Sensitivity of a Smoke Toxicity Test Method to Test Conditions

Nathan D. Marsh, Richard G. Gann, Jason D. Averill, Marc R. Nyden
Experiments have been conducted in the NFPA 269/ASTM E 1678 radiant apparatus to determine the sensitivity of toxic gas generation to atmospheric oxygen availability and to the conformation of the test specimen. CO and HCN generation can be dependent on
