- Abstract
- In an experimental investigation was studied the fire environment along the escape route from a basement shelter--at various fires in the building above. The escape route was through a basement compartment (floor 0), through the lower part of the staircase well and out from floor 1. The measured components of the fire environment were the gas temperature T, the optical smoke density OD and the concentration of carbon monoxide CO. In the series of 12 experiments were varied the site of the fire, the ventilation openings and the fuel. Some results were as follows. Safe escape was possible when the fire was at floor 2. Escape was not possible, when the fire was at floor 1--in an apartment adjoined to the stairwell. The fire environment in the basement was not severely impaired in any experiment.
