Identification of fire gases in early stages of fire in laboratory scaled and full scale fire experiments
A series of reduced scale emulations of standard fires in a 2 m3 enclosure have been developed for studies at laboratory scale enabling useful comparison and correlation with full scale EN54/7 and UL268 test fires. This makes study of standard test fire conditions and products substantially more …

Predicting toxic gas concentrations resulting from enclosure fires using the local equivalence ratio concept linked to fire field models
Fire field modelling is based on the techniques of computational fluid dynamics (CFD), which provide detailed variable solutions throughout the computational domain quickly, repeatedly and cheaply compared with fire experiments. A main component of fire effluent are toxic gases and one of the main …

Radio propagation in fire environments.
Radio propagation in the presence of fire is known to be problematic to communications. In this thesis we use both experimental and theoretical approaches to examine and understand radio propagation in fire environments. Propagation is examined for three small scale fires with broadband equipment …

The transport of high concentrations of carbon monoxide to locations remote from the burning compartment
… entrainment on the transport of CO in building fires, and to develop a procedure for estimating CO levels during a building fire. Experiments were performed with an insulated 1/4-scale room connected to the side of a 1/4-scale hallway forming a L-shape. Measurements of CO, unburned hydrocarbons …

The transport and remote oxidation of compartment fire exhaust gases
… majority of deaths and injuries in compartment fires result from inhalation of the toxic gas, carbon monoxide (CO), especially in locations remote from the burning compartment. This causes the transport and oxidation of CO in burning buildings to become an important topic. Studies have been …

Practical Assessment of the Dependence of Fire Service Intervention Times on Life Safety
… human survivability during accidental dwelling fires (ADF). It also establishes a time window within which the fire service is likely to affect a rescue of the occupants from ADFs. Through a comparison of these two timelines, the likelihood that the fire service will rescue an occupant before …

Empirical and experimental studies of flashover in compartment fire
The development of enclosure fires; the essence, characteristics, hazard, prevention and control of flashover; characteristics of modem buildings and flashover in them; and distinction between backdraught and flashover were all summarized. The basic theories of flashover, major variables, research …

Burnthrough Modeling of Marine Grade Aluminum Alloy Structural Plates Exposed to Fire
Current fire induced burnthrough models of aluminum typically rely solely on temperature thresholds and cannot accurately capture either the occurrence or the time to burnthrough. This research experimentally explores the fire induced burnthrough phenomenon of AA6061-T651 plates under multiple …

Analysis of tenability, ventilation, and water application in large-scale residential fires
… presents the analysis of large-scale residential fire experiments that were performed at Underwriters Laboratories in Northbrook, Illinois. These experiments were focused on the tenability conditions within residential fire environments and the effect of ventilation and water application on the …

Computational Study of Parameters Affecting Electric Cabinet Fire Heat Release Rate
Electrical cabinet fires occur frequently in commercial and industrial facilities. However, the severity of these fire events varies widely, making it difficult to estimate the fire growth and size with certainty. This study aims to identify the significant parameters that affect electrical cabinet …
