An analysis of the Wright Patterson full-scale engine nacelle fire suppression experiments by Anthony Hamins( Book )

4 editions published between 1997 and 1998 in English and held by 131 WorldCat member libraries worldwide

The SPGG effluent which contained a significant percentage of K2CO3 particulate was particularly effective for re-ignition protection, a scenario which dominates agent mass requirements for the compressed halogenated liquids. A number of measurements were made during the suppression tests. Measurements included gas temperatures, the re-ignition source temperature, the cold-flow agent concentrations (no fuel spray or fire present), and velocity measurements. This information was utilized to gain insight into the mechanisms of fire suppression with the different suppressant types. A simple model for SPGG delivery was developed. Assuming plug type flow, the transient average agent concentrations were calculated in the nacelle and compared to measurements. The results give reasonable agreement

Aspects of the motor vehicle fire threat from flammable liquid spills on a road surface by T. J Ohlemiller( Book )

4 editions published in 1998 in English and held by 8 WorldCat member libraries worldwide

Spills of flammable liquids, particularly gasoline, pose a significant fire hazard subsequent to a motor vehicle crash. Various considerations pertaining to making quantitative estimates of the level of hazard are discussed here. These include preliminary data on the fire point of gasoline/vehcile fluid mixes, estimates of fire size resulting from various gasoline leak rates, limited data on heat transfer from burning gasoline spills and an approximate basis for estimating the heat flux exposure time that is required to ignite the surface of atypical plastic component
Performance of home smoke alarms : analysis of the response of several available technologies in residential fire settings by Richard W Bukowski( )

4 editions published between 2007 and 2008 in English and held by 7 WorldCat member libraries worldwide

Consistent with prior findings, ionization type alarms provide somewhat better response to flaming fires than photoelectric alarms, and photoelectric alarms provide (often) considerably faster response to smoldering fires than ionization type alarms. Escape times in this study were systematically shorter than those found in a similar study conducted in the 1970's. This is related to some combination of faster fire development times for today's products that provide the main fuel sources for fires, such as upholstered furniture and mattresses, different criteria for time to untenable conditions, and improved understanding of the speed and range of threats to tenability
A framework for utilizing fire property tests by Thomas G Cleary( Book )

4 editions published in 1991 in English and held by 6 WorldCat member libraries worldwide

A complete approximate set of equations is developed to describe fire spread and its resultant energy release over a surface. Wall, floor, and ceiling orientations are considered. The needed model data are couched in terms of available test method results, e.g., Cone Calorimeter and LIFT apparatus. Several applications are presented to show how energy release rates can be predicted and how well they represent real data from full-scale and model room lining experiments

The influence of ignition source on the flaming fire hazard of upholstered furniture by Thomas G Cleary( Book )

4 editions published in 1992 in English and held by 4 WorldCat member libraries worldwide

When a detector was not present, the results from the limited number of scenarios considered confirm the importance of a low peak heat release rate and a slow rate of rise to lessen the hazard of upholstered furniture fires. No one of the ignition scenarios examined consistently yielded the greatest potential hazard for all chair types tested when ignition and sustained burning was achieved. It is recommended that the hazards of upholstered furniture for residential use be assessed on the basis of resistance to small flame and cigarette ignition combined with peak heat release rate and time to peak subsequent to ignition by a strong source such as the CTB 133 equivalent gas burner
Predicting smoke and carbon monoxide detector response in the ceiling jet in the presence of a smoke layer by William D Davis( Book )

1 edition published in 2003 in English and held by 3 WorldCat member libraries worldwide

In this paper, an algorithm for predicting smoke or carbon monoxide concentration in the ceiling jet in the presence of a smoke layer is developed. The analysis will be restricted to fires that produce turbulent plumes and can be represented by axisymmetric point sources. The predictions of the algorithm for smoke and carbon monoxide are compared with experiments. Once the smoke or carbon monoxide concentration in the ceiling jet is predicted, the activation times for detectors can be calculated using a model for detector activation
Results from a full-scale smoke alarm sensitivity study by T. G Cleary( )

Smoke alarm performance in kitchen fires and nuisance alarm scenarios by Thomas G Cleary( Book )

2 editions published in 2013 in English and held by 3 WorldCat member libraries worldwide

Experiments were conducted to assess the performance of various residential smoke alarms to kitchen fires and nuisance alarm cooking scenarios. A structure representing a kitchen, living room and hallway was constructed to conduct the experiments. Eight different residential smoke alarms types, two photoelectric models (P1 and P2), two ionization models (I1 and I2), two dual sensor photoelectric/ionization models(D1 and D2), and two multi-sensor, intelligent models (M1 and M2) were used in this study. The data gathered provided insight into the susceptibility of alarm activation from exposures to typical cooking events and alarm times for actual kitchen fires. The effects of alarm technology and installation location on the propensity of an alarm to activate were examined. In the kitchen fire experiments, all smoke alarms responded before hazardous conditions developed. An ionization alarm (I1) tended to respond first compared to other co-located alarms. Results show smoke alarms placed greater than 6 m from the kitchen range may provide less than 120 s of available safe egress time, which suggests the importance of a more central alarm location closer to the kitchen for this configuration. Experiments were conducted to determine an alarm?s propensity to activate when exposed to particulates generated from eight typical cooking activities including toasting, frying, baking and broiling. In most cases, the propensity to nuisance alarm decreased as the distance from the cooking source increased. Two alarms, I1 and D2, experienced more nuisance alarm activations across the eight cooking activities than the other alarms. The remaining alarms experienced about the same combined nuisance alarm frequency by averaging all cooking events for installation locations outside the kitchen. Experiments showed combustible materials typically found on a counter top can spread flames to overhead cabinets, and a single empty 0.6 m wide 1.0 m tall wood-framed, pressboard cabinet can produce a peak heat release rate nearly sufficient to flashover a small room. Alternatively, protective metal barrier on the bottom and side facing the range tended to limit the spread of flames to the cabinet and reduce the heat release rate
Flammability characterization of foam plastics by Thomas G Cleary( Book )

4 editions published in 1991 in English and held by 3 WorldCat member libraries worldwide

The results of a study to identify an alternative test protocol to the Steiner Tunnel Test as a measure of flammability for foamed plastic are presented. New fire test apparatus namely the Cone Calorimeter and Lateral Ignition and Flame Spread apparatus were used to more completely characterize foamed plastic flammability. Key flammability properties obtained from these apparatuses describe ignitability, flame spread rate, rate of heat release, and smoke obscuration. An extensive data set of these flammability properties for 10 selected foamed plastics was generated. The tested materials included melting foams (polystyrene foams) and charring foams (polyurethanes, polyisocyanurate and phenolic foams). The effects of melting and dripping was limited by testing the materials in the horizontal orientation

Performance of dual photoelectric/ionization smoke alarms in full-scale fire tests by Thomas G Cleary( Book )

1 edition published in 2009 in English and held by 1 WorldCat member library worldwide

While there appears to be no consensus on sensitivity setting for ionization sensors, it may be desirable to tailor sensor sensitivities in dual alarms for specific applications, such as near kitchens where reducing nuisance alarms may be a goal, or in bedrooms where higher smoke sensitivity may be a goal
