摘要:

AbstractA theoretical model of compartment fires in the post‐flashover stage is presented. The model incorporates the stirred reactor assumption and window flow approximation of Kawagoe, but treats fuel burning rates and burning regimes in a theoretical manner. The resulting formulation preserves the important features of the fire behavior but is simple enough to permit use for building fire safety design purpose

摘要:

AbstractA simple analytical model has been developed to determine the time required for a room to fill with products of combustion from a small fire. The room is assumed to be closed except for small openings at either the floor or ceiling level and the assumption is made that the leak is large enough to allow the transient pressure term in the energy equation to be neglected. Products of combustion are assumed to occupy a layer next to the ceiling and the model predicts the growth of the thickness and the mean density of this layer as a function of time. The analysis shows that times required to fill a typical room are small. For example, a typical bedroom fills with products from a 20 kW fire in several minutes. The time required to fill a room and the mean density of ceiling layer are determined in terms of fire size, room geometry, leak position, fire elevation and geometry.

摘要:

AbstractThe influence of flame retardants and stabilizers on the thermooxidative and thermal stability of polyethylene systems has been investigated. In the present study 18 polymeric composites were prepared and their stabilities investigated by static and dynamic methods; their flammability parameters were also determined.

摘要:

AbstractRelative toxicity test data on 270 materials are presented, based on test procedures developed at the University of San Francisco. The effects of chemical composition, using data on 13 types of synthetic polymers and eight types of fabrics, are discussed. Selected materials were evaluated using nine test conditions with the USF method, and using methods developed at the FAA Civil Aeromedical Institute, Douglas Aircraft Company and San Jose State University.

摘要:

AbstractFurther evidence has been obtained to suggest that the fire retardation efficiencies of several organo‐bromine compounds, as measured by the limiting oxygen index method, are independent of the type of carbon‐bromine bond, depending almost entirely upon the bromine concentration. Linear regression analysis has confirmed the linearity of the relationship between the limiting oxygen index method and the bromine concentration. The fire retardation efficiency (as measured by the limiting oxygen index method) of the organo‐bromine compounds does, however, depend to a marked extent upon the subs
