AbstractA series of experiments at the National Fire Laboratory (NFL), measured the effects of water spray from automatic sprinklers on the temperature, pressure, oxygen, carbon dioxide and carbon monoxide levels in a building under fire conditions. The project was jointly funded by the American Society of Heating, Refrigerating and Air Conditioning Engineers, Inc.(ASHRAE) and the National Research Council of Canada.Sprinklers act quickly to extinguish fires before they become large enough to create dangerous smoke conditions in a building. In these tests, however, particular attention was paid to shielded fires, in which an obstacle prevented water spray from extinguishing the burning fuel. In an office occupancy, for example, shielded fires could develop in combustible materials stored under a table or in a closet, or in compact mobile shelving units for paper files. In shielded fires, sprinklers restrain the burning rate, prevent firespread and reduce temperatures, but are not able to eliminate the smoke hazard in the building.
